Stress & Relaxation

Calm a Busy Mind

A busy mind, with thoughts that race, replay or loop back to the same worry, is one of the most common reasons people feel unsettled, and there are well-studied skills that can loosen its grip. This page is about racing thoughts, rumination and worry; in-the-moment calming, body tension, pressure and bedtime wind-down have their own pages.

General information, not medical advice. Last updated October 31, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.

Start here

Get the worry out of your head: write it down, then choose a short daily "worry time" (the NHS suggests about 10 or 15 minutes) and tell yourself "I'll set that aside for worry time" when it pops up.
Sort each worry into "I can do something about this" (make one specific plan: what, how, when) and "I can't" (practise letting it be and turning your attention back to what you are doing).
Practise noticing thoughts as passing mental events for a few minutes a day, and add regular movement or a walk outdoors.

Be careful with

Trying hard to push thoughts away usually backfires. Aim to notice them and let them pass, not to force them out.
Meditation and mindfulness are usually safe, but a review found that about 1 in 12 people reported a negative effect such as more anxiety or low mood. Stop or change the practice if it makes things worse, and choose a trained teacher if you have a trauma history.
Do not use alcohol, cigarettes, gambling or drugs to quieten your mind, and do not stop a prescribed medicine on your own. Supplements and herbs can interact with medicines, so ask a pharmacist or doctor first, especially in pregnancy or breastfeeding.

Get help when

Worry that is hard to control on most days for 6 months or more, together with symptoms such as restlessness, tiredness, poor concentration, irritability, muscle tension or poor sleep (the NIMH and NHS describe generalised anxiety disorder this way). A clinician can assess this; this page cannot.
Sudden attacks of intense fear with a racing heart or breathlessness, or thoughts and memories of a frightening event that keep intruding: see the panic and trauma pages and talk to a clinician.
Low mood, loss of interest or hopelessness along with the brooding. Rumination is common in depression.
Thoughts of harming yourself. In the US the NIMH names the 988 Suicide & Crisis Lifeline (call or text 988); in the UK the NHS names Samaritans on 116 123. Elsewhere, contact local emergency services.

About Calm a Busy Mind

What this goal means

A busy mind has three common faces. Racing thoughts are many thoughts moving fast. Rumination is going over the same problem or past event again and again. Worry is thinking ahead about what might go wrong. They often blend together, and all three can leave you tired and tense.

Some mental wandering is normal. In a smartphone study, people's minds wandered to something other than the task at hand almost as often as they stayed on it, and people tended to be less happy when they were wandering. This was an observational study, so it shows an association rather than a cause.

^1,2

What it can feel like

Common experiences are thoughts that will not switch off, replaying a conversation, rehearsing worst cases, difficulty concentrating, feeling mentally tired but unable to rest, and getting stuck in "what if" loops. The NHS describes how it is easy to live "in our heads", caught up in thoughts without noticing how they drive emotions and behaviour.

Researchers describe rumination and worry as "perseverative" thinking, thinking that keeps going without moving you toward a solution.

^3,4

What can feed it

Symptoms are often worse during stressful times, such as illness, exams or conflict (NIMH). Poor sleep, a lot of caffeine and relying on alcohol or other substances to unwind can make it harder to settle the mind (NHS). Avoiding what worries you can also keep worry going, which is why the NHS advises building up gradually to worrying situations rather than avoiding them.

Anxiety disorders, depression, trauma-related stress and some physical problems can all sit behind an over-active mind. Checking for these is part of good care.

^5,6

When persistent worry may be an anxiety disorder

Worrying is part of life. According to the NIMH, generalised anxiety disorder (GAD) involves worry that is hard to control on most days for at least 6 months, plus at least three symptoms such as feeling restless or on edge, fatigue, trouble concentrating, irritability, muscle tension or sleep problems. The NHS adds that most people feel anxious sometimes and that it does not always mean GAD.

Only a clinician can tell you whether you have an anxiety disorder, so this page does not try to. If your worry fits this picture, see the anxiety disorders page and consider speaking to a doctor or a talking therapy service.

^5,6

Realistic expectations

Skills such as worry time, mindfulness and CBT-style thinking exercises take practice, and the NHS says it may feel hard at first to stop thoughts returning to a worry but gets easier as the habit settles. In a review of mindfulness programmes, the improvement in anxiety was moderate rather than dramatic, and smaller at 3 to 6 months than at 8 weeks.

The aim is not an empty mind. NHS guidance on mindfulness says it is not about making thoughts go away but seeing them as mental events that come and go.

^2,7,3

Who this applies to

Adults whose main difficulty is racing, looping or worried thinking. If you are mainly dealing with tension in the body, a sense of too much to do, pressure at work or trouble sleeping, see the linked goals. Children and teenagers may worry about different things and need age-appropriate support from a clinician or school.

A manageable starting plan

An educational starting point, not a personal prescription. Adjust it to your own situation and any advice from your clinician.

Your first actions

Choose a daily worry time (10 to 15 minutes, not near bedtime) and a notebook; postpone worries to that slot.
At worry time, sort each worry into "can act" (write one specific step and when) or "cannot" (note it and let go).
Practise 5 to 10 minutes of mindfulness daily, returning attention each time the mind wanders.
Move your body most days, ideally with some time outdoors.

Optional additions

Try a reflective journal entry (thoughts, feelings, next step) after a stressful event.
Explore an evidence-based online or group programme for worry or rumination.
Cut caffeine back gradually and keep meals regular.

What to track

How many hours a day your mind feels busy, and what sets it off.
Whether worry time and postponing are getting easier.
Sleep, caffeine, alcohol and any new supplement or medicine.

When to reassess

Give the skills a few weeks; mindfulness studies measured effects at around 8 weeks. If your mind is not calming, if worry is hard to control on most days, or it has gone on for months, speak to a doctor or therapist; they can assess for an anxiety disorder, depression or other causes and talk through talking therapies.

When to seek professional support

See a doctor if worry is hard to control on most days for 6 months or more, or if it affects work, relationships or sleep.
Seek urgent help for thoughts of harming yourself.
Talk to a friend, family member, health professional or counsellor about how you feel.

What helps

Ordered by how well the research supports each step. Evidence strength is shown on every card; precautions sit next to the advice.

Start here

Write your worries down

Low certainty

Addresses: Gets thoughts out of your head so they can be looked at one at a time

Why it may help: The NHS suggests writing worries on paper or in a notes app to clear your mind and make it easier to work through concerns one by one. A large meta-analysis of 146 randomized studies of writing about personal topics found a small average benefit (r = 0.075), so treat it as a helpful habit rather than a cure.

How to apply it: Spend a few minutes writing down what is on your mind, without editing. Then close the notebook. Try to move from "what if" to "what could I do about it".

Who it may suit: Anyone who lies awake or loops over worries during the day.

Precautions: Writing only about painful feelings, over and over, may not help; see the journaling item below. If writing about a traumatic experience brings strong distress, stop and talk to a clinician.

^2,8

Relax Before Bed →

Set a daily "worry time"

Low certainty

Addresses: Contains worry to a set slot so it takes up less of the rest of the day

Why it may help: The NHS suggests a short daily period, say 10 or 15 minutes, to write worries down and look for solutions, and recommends telling yourself "I'll set that aside for my worry time" when a worry appears at other times. In a randomized trial of 53 people with high trait worry, two weeks of a daily 30-minute worry period held at a set time and place reduced worry, anxiety and insomnia symptoms more than a comparison group, though not depression. The authors called the results preliminary.

How to apply it: Pick the same time and place each day, earlier than bedtime. During that time, write down worries and any next steps. Outside it, gently postpone new worries until the next session.

Who it may suit: People whose worries spill across the whole day.

Precautions: Studied over two weeks in a small group; larger and longer trials are needed. If worry feels unmanageable or the exercise raises distress, speak to a clinician.

^2,9,10

Sort worries with the "worry tree" and make one specific plan

Low certainty

Addresses: Separates problems you can act on from "what ifs" you cannot control

Why it may help: The NHS describes a worry tree that helps you tell solvable problems from hypothetical worries beyond your control. For solvable ones it advises a specific plan: what would you do, how, and when. For worries you cannot do anything about, it advises acknowledging this, accepting it and moving on. A systematic review of 19 studies found that cognitive behavioural and mindfulness-based approaches may reduce both rumination and worry.

How to apply it: Ask: "Is there anything practical I can do?" If yes, write the first small step and when you will do it. If no, name it as outside your control and turn your attention to something you can do now.

Who it may suit: Anyone whose worries are mostly about real-life problems.

Precautions: Self-help tools are not a substitute for care if worry is severe or lasts for months.

^2,4,11

Therapy for anxiety and stress →

Step back: notice and name your thoughts

Low certainty

Addresses: Helps you see thoughts as events passing through rather than facts you must follow

Why it may help: NHS mindfulness guidance suggests silently naming thoughts and feelings, for example "Here's the thought that I might fail that exam" or "This is anxiety", and asking "Is trying to solve this by brooding about it helpful, or am I just getting caught up in my thoughts?" This is the everyday form of what therapists call defusion or decentring. The tip on its own has not been tested in isolation in the sources read; it comes from mindfulness and acceptance-based approaches that have been studied as full programmes.

How to apply it: When a loop starts, pause, label it ("worrying", "planning", "replaying"), take a slower breath and bring your attention to what you can see, hear or feel right now.

Who it may suit: People who get pulled into thought loops.

Precautions: If noticing thoughts brings up distressing memories or panic, stop and seek support from a trained teacher or therapist.

^3,12,5

Meditation and mindfulness →

A short, regular mindfulness practice

Moderate certainty

Addresses: Builds the skill of noticing a busy mind and returning attention

Why it may help: A meta-analysis of 47 randomized trials (3,515 participants) rated the evidence that mindfulness meditation programmes improve anxiety as moderate. Another meta-analysis found mindfulness-based therapy moderately effective for anxiety and mood symptoms, with effects similar to CBT in nine comparisons. NCCIH says much mindfulness research has been preliminary and may have been interpreted too optimistically.

How to apply it: Start with 5 to 10 minutes a day: sit comfortably, rest attention on the breath, and each time the mind wanders, notice it and come back. Guided audio can help. In the meta-analysis, benefits were measured at about 8 weeks and again at 3 to 6 months.

Who it may suit: Adults who can set aside a few minutes a day and want a non-drug skill.

Precautions: Adverse effects are not rare in the research (see Evidence & Safety). Choose a trained teacher and tell them about any trauma history or mental health condition.

^7,13,14,3,15

Meditation → Mindfulness and meditation for stress →

Additional options

Regular exercise

Low certainty

Addresses: Gives the mind something else to do and may ease anxiety symptoms

Why it may help: A meta-analysis of six randomized trials (262 adults with anxiety or stress-related disorders) found exercise reduced anxiety symptoms more than control conditions, with a moderate effect. The NHS lists regular activity such as running, walking, swimming and yoga as ways to reduce anxiety and stress. NHS mindfulness guidance also notes some people find an over-busy mind easier to cope with while doing gentle yoga or walking.

How to apply it: Choose something you enjoy and build up gradually. Gentle walking counts.

Who it may suit: Most adults.

Precautions: Only six small trials in the meta-analysis. Check with a clinician before starting if you have a heart or lung condition or are pregnant.

^16,6,3

Yoga → Tai chi → Movement, yoga and tai chi for stress →

A walk in nature

Low certainty

Addresses: May quieten rumination

Why it may help: In an experiment with healthy volunteers, a 90-minute walk in a natural setting reduced self-reported rumination and activity in a brain area linked to rumination, while a walk in an urban setting did not.

How to apply it: Choose a park, trail, garden or waterside walk. Notice what you can see, hear and smell rather than replaying thoughts.

Who it may suit: People who tend to brood and have access to green space.

Precautions: One experiment in healthy people; it is not known how long the effect lasts or whether it helps people with an anxiety disorder.

¹⁷

Journaling that includes reflection

Low certainty

Addresses: Helps make sense of a stressful event rather than just reliving it

Why it may help: In a trial of 122 students writing for a month about a stressful event, those who wrote about both thoughts and feelings gained a greater awareness of the positive aspects of the experience than those who wrote only about emotions or about neutral media events. Those writing only about emotion reported more severe illness symptoms during the study. Across 146 randomized studies, the average benefit of such writing is small.

How to apply it: Write for 10 to 20 minutes about what happened, what you think about it, and what you might learn or do next. If it feels like going round in circles, switch to planning or stop for the day.

Who it may suit: People who replay a specific stressful event.

Precautions: Study participants were students. Writing about traumatic events can stir up distress; do not push through, and talk to a clinician if it is overwhelming.

^18,8

Acceptance and defusion skills

Moderate certainty

Addresses: Changes your relationship to thoughts rather than fighting them

Why it may help: Acceptance and commitment therapy (ACT) teaches nonjudgmental acceptance of thoughts and engagement in meaningful activity. A meta-analysis of 39 randomized trials (1,821 patients) found ACT outperformed control conditions and did not differ significantly from established treatments such as CBT. The NIMH says there is a growing body of research on ACT for generalised anxiety disorder. The defusion exercises within ACT have not been isolated in the studies read here.

How to apply it: Try treating thoughts as "I'm having the thought that...", and ask whether acting on a thought serves what matters to you. A therapist or structured self-help programme can guide this.

Who it may suit: People who feel pushed around by their thoughts and want a skill-based approach.

Precautions: Best learned with a trained practitioner if you are dealing with an anxiety disorder or past trauma.

^12,5

Still being studied

Attention bias and interpretation training (computer exercises)

Very low certainty

Addresses: Meant to retrain automatic attention and interpretation habits

Why it may help: A network meta-analysis of 85 randomized trials found consistent but small benefits for anxiety from cognitive bias modification, with the clearest signal for interpretation bias modification. The authors said heterogeneity and risk of bias undermine reliability, and prediction intervals included no effect. Only four trials had low risk of bias.

How to apply it: These are usually computer tasks used in research settings.

Who it may suit: Mainly of interest in research for now.

Precautions: Not an established self-help method. Do not use in place of therapy for an anxiety disorder.

¹⁹

Guided online programmes for rumination and worry

Low certainty

Addresses: Offers CBT or mindfulness-based skills with less cost and travel

Why it may help: In a systematic review of 19 studies, both internet-delivered and face-to-face mindfulness-based and cognitive behavioural treatments looked useful for reducing rumination and worry. The review covered studies from 2002 to 2012 and called for more research.

How to apply it: Look for programmes that are structured, evidence-based and from a reputable health service, university or clinic.

Who it may suit: Adults who prefer to work at their own pace.

Precautions: Quality varies widely between apps and programmes; this review did not test any specific product.

⁴

Food & nutrition

Steady eating and caffeine

The NHS advises eating a healthy diet with regular meals to keep energy levels stable and limiting lots of coffee, tea, cola and energy drinks because caffeine can disrupt sleep and make anxiety harder to control. These are general recommendations from a health service for anxiety, not proven treatments for a busy mind.

In a meta-analysis, caffeine at roughly five cups of coffee induced panic attacks in about half of patients with panic disorder and increased anxiety in healthy adults at those doses. Less is known about smaller amounts.

^6,20

Alcohol

The NHS advises against using alcohol to relieve anxiety, because it can contribute to poor mental health. If you drink, avoid using it as a way to switch your mind off.

⁶

Foods and drinks that have not been proven

No food has been shown to quieten racing thoughts. L-theanine, an amino acid found in tea, has been studied as an isolated supplement, not as tea, and the reviewers said studies that include it in the regular diet are still needed. A warm, caffeine-free drink such as chamomile tea can be a pleasant pause, which is a habit rather than a treatment.

^21,22

Remedies & supplements

Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.

Chamomile

Low certainty

Studied form and route: Tea or standardised extract

Intended outcome: Anxiety and sleep quality

Human evidence: A meta-analysis of 12 trials found a small improvement in generalised anxiety scores at 2 and 4 weeks, and improved sleep quality, but three trials of state (situational) anxiety showed no clear difference. NCCIH says two studies suggest a chamomile supplement might help generalised anxiety disorder but they are preliminary.

Traditional use: Widely used as a calming evening tea.

Limits: Small trials, mixed results, and extracts differed from tea.

Interactions and precautions: NCCIH lists headache, dizziness and digestive or muscle problems as reported side effects. Check with a pharmacist if you take medicines.

^22,23

Chamomile → Chamomile tea →

Lavender (oral lavender oil)

Low certainty

Studied form and route: Standardised oral capsule (a specific proprietary product was studied)

Intended outcome: Anxiety symptoms

Human evidence: NCCIH says studies of an oral lavender oil product suggest it might help anxiety, but no definite conclusions can be reached because of small studies; a 2019 analysis of 65 randomized trials suggested oral lavender may help but was limited by low study quality. A meta-analysis of five placebo-controlled trials (1,213 adults) of the proprietary product Silexan found greater reduction in anxiety scores than placebo over ten weeks.

Limits: Results come from one proprietary product; independent confirmation was not checked. This is not the same as lavender tea or essential oil used on skin.

Interactions and precautions: Do not swallow ordinary essential oils. Ask a pharmacist before use with other medicines, and in pregnancy or breastfeeding.

Dose, only as reported in studies: Studied: 80 mg a day for ten weeks of the proprietary product in the meta-analysis. This describes what was studied, not advice to take it.

^23,24

Lavender → Lavender oil →

Ashwagandha

Low certainty

Studied form and route: Root extract capsules

Intended outcome: Stress and anxiety scores

Human evidence: A meta-analysis of nine randomized trials (558 people) found lower perceived stress, anxiety scores and serum cortisol than placebo. Four trials reported mild to moderate side effects.

Traditional use: Described in the meta-analysis as an adaptogenic herb used to prevent and treat psychosomatic disorders.

Limits: Small trials, varied products; the authors say long-term safety needs more information. It is not specific to a busy mind.

Interactions and precautions: Ask a clinician or pharmacist first, especially with other medicines, existing health conditions, pregnancy or breastfeeding.

²⁵

Ashwagandha →

L-theanine

Low certainty

Studied form and route: Amino acid supplement (not tea)

Intended outcome: Stress and anxiety in people under stress

Human evidence: A systematic review of randomized trials suggested that L-theanine supplementation may help reduce stress and anxiety in people exposed to stressful conditions. The reviewers said longer and larger studies are needed to justify its use as a therapeutic agent.

Limits: Short trials, mostly in stressful situations rather than a chronic busy mind.

Interactions and precautions: Check with a pharmacist if you take medicines.

Dose, only as reported in studies: Studied: 200 to 400 mg a day in the review. This describes what was studied, not advice to take it.

²¹

L-theanine →

Passionflower

Not enough evidence

Studied form and route: Herbal extract or tea

Intended outcome: Anxiety

Human evidence: NCCIH says a small amount of research suggests passionflower might help reduce anxiety, including before a dental procedure, but conclusions are not definite.

Limits: Little research; not specific to rumination.

Interactions and precautions: NCCIH considers it safe when taken by mouth; check with a pharmacist if you take sedating medicines or are pregnant.

²³

Passionflower →

Valerian

Not enough evidence

Studied form and route: Root extract or tea

Intended outcome: Anxiety

Human evidence: NCCIH says there is not enough evidence to draw conclusions about whether valerian helps anxiety, and that it is generally safe for short-term use by most adults while long-term safety is unknown.

Limits: Not enough evidence.

Interactions and precautions: May add to drowsiness from alcohol or sedating medicines; ask a pharmacist.

²³

Valerian →

Kava (not suggested)

Evidence against

Studied form and route: Supplement

Intended outcome: None advised

Human evidence: NCCIH says kava may have a small effect on anxiety, but supplements have been linked to a risk of severe liver damage.

Limits: The safety concern outweighs the modest evidence.

Interactions and precautions: Avoid unless a clinician specifically advises it.

²³

Kava →

Therapies & care

Established care for persistent, hard-to-control worry starts with talking therapies, usually cognitive behavioural therapy (CBT); the NHS and NIMH also describe medicines that a doctor may discuss. This page does not recommend medicines or doses, and you should not stop a prescribed medicine on your own. In England, adults can refer themselves to NHS talking therapies without seeing a GP first.

Cognitive behavioural therapy (CBT)

High certainty

Talking therapy CBT helps you notice automatic, unhelpful ways of thinking, question them, understand how they affect emotion and behaviour, and change patterns that keep worry going. The NIMH calls CBT the "gold standard" psychotherapy for anxiety and says it is commonly used for generalised anxiety disorder. The NHS says one of the main treatments a GP may offer is CBT, with a therapist or in a group.

Who it may suit: Adults with persistent worry or anxiety that affects daily life.

Precautions: It takes time and homework between sessions; ask about wait times and online options.

^5,6,11

Therapy for anxiety and stress → Anxiety disorders →

Acceptance and commitment therapy (ACT)

Moderate certainty

Talking therapy ACT encourages nonjudgmental acceptance of thoughts and engagement with meaningful activities, using mindfulness and goal setting. A meta-analysis of 39 randomized trials found it did not differ significantly from established treatments such as CBT, and the NIMH notes growing research for GAD.

Who it may suit: People who want an approach based on accepting thoughts rather than arguing with them.

Precautions: Look for a trained therapist.

^12,5

Therapy for anxiety and stress →

Mindfulness-based programmes (MBSR, MBCT)

Moderate certainty

Group or guided training Structured programmes that teach mindfulness meditation alongside discussion and strategies for applying it to stressful experiences (NCCIH description). A meta-analysis of 209 studies (12,145 participants) found moderate effects overall and no difference from CBT in nine comparisons. NCCIH notes mixed results for anxiety disorders and few long-term effects beyond 2 months in the trials followed up for longer.

Who it may suit: Adults wanting a structured group or guided programme.

Precautions: About 8% of participants in a review reported adverse effects, most often anxiety or depression. Tell the teacher about any trauma history or mental health diagnosis.

^{13,7,26,14,15}

Meditation → Mindfulness and meditation for stress →

Metacognitive therapy

Low certainty

Talking therapy Focuses on beliefs about thinking itself, such as "worry is uncontrollable" or "I must keep ruminating". A meta-analysis (16 studies, 9 controlled, 384 participants with anxiety or depression) found large effects and better results than waitlist and CBT, but the authors cautioned about small samples and few active comparisons.

Who it may suit: People who feel trapped by worry about their worry.

Precautions: Fewer trained therapists; the evidence base is smaller than for CBT. The NHS and NIMH pages read did not cover it.

²⁷

Therapy for anxiety and stress →

Relaxation, breathing and gentle movement

Low certainty

Self-help and mind-body practice The NHS lists calming breathing exercises and activities such as yoga or pilates for GAD. NCCIH says relaxation techniques are generally safe but CBT may be more helpful for at least some anxiety disorders, and that yoga evidence for anxiety disorders is inconclusive.

Who it may suit: People who find body-based calm helps settle thoughts.

Precautions: Occasionally relaxation can increase anxiety or intrusive thoughts; stop if that happens.

^6,23

Breathing exercises → Relaxation techniques → Yoga →

Checking for other causes

Moderate certainty

Clinical assessment A clinician can ask about your symptoms, how long they have lasted and how they affect life, and may do a physical exam to make sure an unrelated physical problem is not behind them. Anxiety often occurs with depression or other conditions, and treatment can be planned for all of them.

Who it may suit: Anyone with persistent worry, poor sleep or concentration problems.

Precautions: Do not self-diagnose.

What to avoid

Habits, products and claims that can get in the way. Never stop a prescribed medicine without talking to the professional who prescribed it.

Risks that apply to most people

Trying to force thoughts out of your mind

Low certainty

Why: In the classic "white bear" experiments, people asked not to think about a white bear mentioned it about once a minute. A review of thought control strategies found that those with promise mostly involve accepting and engaging with unwanted thoughts rather than suppressing them.

Who it applies to: Anyone with intrusive or looping thoughts.

Try instead: Notice the thought, label it and redirect attention; schedule it for worry time.

^10,3

Alcohol, cigarettes, gambling or drugs to quieten the mind

Moderate certainty

Why: The NHS advises against using these to relieve anxiety because they can contribute to poor mental health.

Who it applies to: Anyone using substances to unwind or switch off.

Try instead: Try the calming skills on this page, and ask a clinician for support if you feel you rely on a substance.

⁶

Long periods of rumination while "solving" the problem

Low certainty

Why: NHS mindfulness guidance suggests asking whether brooding is actually helping you solve something or whether you are just getting caught up in thoughts.

Who it applies to: People who go over past events or hypothetical futures for hours.

Try instead: Write the problem down, decide on one concrete next step, and set a time to act.

^3,2

Personal triggers to check

Lots of coffee, tea, cola and energy drinks

Moderate certainty

Why: The NHS says caffeine can disrupt sleep and make anxiety harder to control. A meta-analysis found that caffeine at doses roughly equivalent to 5 cups of coffee triggered panic attacks in about half of people with panic disorder and increased anxiety in healthy adults too.

Who it applies to: People who feel jittery or keyed up, and anyone with panic or an anxiety disorder.

Try instead: Cut down gradually (sudden cuts can cause headaches) and shift caffeine to the morning.

^6,20

Caffeine, alcohol and sleep →

Avoiding the situations you worry about

Moderate certainty

Why: The NHS says not to avoid situations that make you anxious; slowly building up time in worrying situations can gradually reduce anxiety.

Who it applies to: People whose worry is tied to particular situations.

Try instead: Break the situation into small steps and do them gradually, with support from a therapist if it feels too big.

⁶

Too little sleep

Low certainty

Why: The NHS notes enough sleep helps you cope with difficult feelings, and tiredness is part of how worry feels. A busy mind at night is covered on the sleep pages.

Who it applies to: People who are over-tired and ruminate more at night.

Try instead: See the sleep goal pages for wind-down and falling asleep.

⁶

Fall Asleep Faster →

Products that need caution

Kava supplements

Moderate certainty

Why: NCCIH reports that kava may have a small effect on anxiety but has been linked to severe liver damage.

Who it applies to: Anyone considering kava, especially with liver disease or alcohol use.

Try instead: Choose lower-risk options and speak to a clinician first.

²³

Kava →

Supplements bought on the strength of an "anxiety" or "focus" label

Moderate certainty

Why: NCCIH says dietary supplements may have side effects or interact with medicines, and that a label saying "standardized" or "certified" does not guarantee quality or consistency.

Who it applies to: Anyone taking medicines, and people who are pregnant or breastfeeding.

Try instead: Ask a pharmacist before starting, and use the interaction guide.

²³

Medicine interactions →

Unsupported claims

"Meditation means emptying your mind"

Moderate certainty

Why: NHS guidance says mindfulness is not about making thoughts go away but about seeing them as mental events that come and go.

Who it applies to: Anyone who thinks they are "bad at meditating".

Try instead: Expect the mind to wander; the practice is noticing and returning.

"Natural calming supplements are proven"

Moderate certainty

Why: NCCIH describes the evidence for chamomile, lavender, passionflower, valerian and others as preliminary, limited or inconclusive.

Who it applies to: Product labels and social media.

Try instead: Treat supplements as an optional extra to discuss with a pharmacist, not a replacement for skills or care.

²³

Supplements, teas and adaptogens for stress compared →

Common mistakes

Waiting for months with worry that is hard to control

Moderate certainty

Why: The NHS says to see a GP if you think you might have GAD or if treatments are not helping; the NIMH describes GAD as worry that is hard to control on most days for at least 6 months along with other symptoms.

Who it applies to: Anyone whose worry affects work, relationships or sleep.

Try instead: Book an appointment, or use a self-referral talking therapy service if one is available where you live.

^6,5

Anxiety disorders →

Treating a skill as a quick fix

Low certainty

Why: Worry time, mindfulness and thinking skills need repetition. A mindfulness review found smaller effects at 3 to 6 months than at 8 weeks, and the NHS notes the habit of postponing worry gets easier with time.

Who it applies to: Anyone who tries a technique once and gives up.

Try instead: Give a technique a few weeks and track whether it helps.

^7,2

Journaling that only vents

Low certainty

Why: In one trial, writers focusing on emotions alone reported more severe illness symptoms than writers who also processed thoughts.

Who it applies to: People who write mostly about distress.

Try instead: Add reflection and next steps, or move on to planning.

Evidence & safety

What the research shows

Health agencies and reviews agree that CBT-style worry skills, acceptance-based approaches and mindfulness can help with worry and rumination, with the strongest and best-established evidence for CBT. Mindfulness programmes show moderate benefits for anxiety, though effects are smaller later and some people report negative effects. Single self-help tips such as worry time, writing and nature walks have small or preliminary studies. Herbs and supplements have limited, low-certainty evidence.

Limits of the evidence

Several trials were small, short or used healthy volunteers or students.
Mindfulness trials often compare against waiting lists or education and may be interpreted too optimistically (NCCIH).
Reviews of rumination and worry treatments covered studies up to 2012 and mixed different methods.
Computer-based attention training has small, unreliable effects.
Supplement products vary in strength and quality, and a lavender product was studied in a proprietary form.
Study numbers on this page come from abstracts and agency pages, not full texts.

Precautions and interactions

Check supplements and herbs with a pharmacist if you take any medicine.
Do not stop a prescribed medicine without speaking to your prescriber.
Meditation can occasionally bring on anxiety, low mood or unpleasant thoughts; stop and seek advice if that happens.

Life-stage considerations

Pregnancy and breastfeeding: talk to a clinician before using any herb or supplement. The NIMH notes anxiety can occur during pregnancy and after birth, and the NHS says a midwife, doctor or health visitor can help.
Children and teenagers: worries often focus on school, friendships and the future; talk to a paediatrician, GP or school counsellor rather than self-treating with supplements.
Older adults: more likely to take several medicines, so check interactions before any herb or supplement.

Claim checks

You can stop unwanted thoughts by pushing them away

Low certainty

In the classic experiment, people told not to think of a white bear mentioned it about once a minute. A review of thought control research found the more promising strategies mostly involve accepting thoughts, postponing them or shifting attention.

¹⁰

Mindfulness works as well as CBT

Mixed findings

A large meta-analysis found no difference in nine comparisons, but NCCIH notes mixed results in anxiety disorders and that only some mindfulness approaches matched CBT. CBT remains the best-established first-line therapy.

^13,23,5

Meditation is risk-free

Moderate certainty

A review of 83 studies found about 8% of participants reported adverse effects, most often anxiety and depression.

^15,14

Brain-training apps will fix racing thoughts

Very low certainty

A network meta-analysis found small, unreliable benefits from attention and interpretation training, with high risk of bias.

¹⁹

A busy mind means I have an anxiety disorder

Moderate certainty

Occasional worry is normal. The NIMH describes GAD as hard-to-control worry on most days for at least 6 months plus other symptoms; only a clinician can diagnose.

^5,6

Calming herbs and supplements are proven

Low certainty

NCCIH describes most evidence as preliminary, limited or inconclusive, with safety concerns for kava.

Questions people ask

Why can't I stop my thoughts?

Minds wander a lot; in one smartphone study they wandered nearly as often as they stayed on task. Trying to push thoughts away tends to make them return, so skills focus on noticing, postponing or accepting them instead.

What is the difference between worry and rumination?

Worry looks ahead at what might go wrong; rumination goes back over past events or problems. Both are repetitive thinking that does not lead to a solution. Many people experience both.

What is "worry time" and does it work?

The NHS describes a short daily period, say 10 or 15 minutes, to write worries and look for solutions, postponing worries at other times. In one small trial of 53 people, a daily 30-minute worry period over two weeks reduced worry and anxiety more than a comparison group; the authors called it preliminary.

Does mindfulness really help a busy mind?

A meta-analysis of 47 trials found moderate evidence of improved anxiety, and a review of treatments for rumination and worry suggested mindfulness-based and cognitive behavioural approaches may help. Effects were smaller at 3 to 6 months and not everyone benefits; the NHS says it can make some people feel worse.

Can meditation make anxiety worse?

It can for some people. A review of 83 studies found about 8% reported negative effects, most often anxiety or depression. If this happens, stop and speak to a teacher or clinician.

Does exercise help with racing thoughts?

A meta-analysis of six trials found exercise reduced anxiety symptoms in people with anxiety or stress-related disorders, and one experiment found a 90-minute nature walk reduced rumination in healthy volunteers. Evidence for racing thoughts in particular is limited.

Will journaling help?

Writing about stressful experiences has a small average benefit across 146 randomized studies. In one trial, writing about both thoughts and feelings was better than writing only about emotions. Add reflection and next steps, and stop if it makes you feel worse.

Is persistent worry an anxiety disorder?

It might be. The NIMH describes generalised anxiety disorder as worry that is hard to control on most days for at least 6 months, with other symptoms such as restlessness, fatigue or sleep problems. Only a clinician can diagnose it, so see a doctor if this sounds like you.

What kind of professional help is there?

The NHS and NIMH both describe CBT as a main treatment for generalised anxiety disorder, and the NIMH also describes acceptance and commitment therapy. Doctors may discuss medicines too. In England adults can refer themselves to NHS talking therapies.

Do herbs or supplements quiet the mind?

Evidence is limited. NCCIH says chamomile and lavender have preliminary results, passionflower has little research and kava has been linked to severe liver damage. Ask a pharmacist before trying anything, especially with medicines.

Does caffeine make my mind busier?

The NHS says caffeine can disrupt sleep and make anxiety harder to control. A meta-analysis found large doses (about five cups of coffee) triggered panic attacks in many people with panic disorder and raised anxiety in healthy adults.
