Breathe Easier
Support Respiratory Recovery After Illness
After a chest infection, bronchitis, pneumonia or COVID-19, a cough, tiredness and some breathlessness can linger for weeks after the worst is over, and most people can ease through this with rest, fluids, patience and a gradual return to activity. This page is about the weeks of recovery after a respiratory illness; coping with the illness itself, returning to routines and rebuilding fitness each have their own pages.
General information, not medical advice. Last updated November 1, 2026. Written by the AlternativeMed editorial team. Not medically reviewed.
Start here
- Expect a slow finish: a cough after a chest infection often takes around three weeks to settle, so give yourself time, drink plenty of fluids and rest when you need to.
- Keep smoke and vaping away from your lungs while they heal, and ask for support if you want to stop.
- Build activity back in small steps, such as short walks, and stop and rest if your breathlessness or tiredness gets worse.
Be careful with
- Do not use cough medicines to suppress a chesty cough from pneumonia: the NHS says coughing helps your body get rid of the infection. Ask a pharmacist or doctor before using any cough product.
- Do not give honey to a baby under 1 year old, and be careful with hot drinks and steam around children.
- Herbal products can interact with medicines and are mostly unstudied in pregnancy and breastfeeding; check with a pharmacist or doctor first, and never stop or replace a prescribed inhaler, antibiotic or other medicine because of something you read here.
Get help when
- Call emergency services (999 in the UK, as named by the NHS) for severe trouble breathing, being unable to speak, pale, blue or grey lips or skin, sudden confusion, or coughing up blood.
- Get urgent advice (an urgent GP appointment or NHS 111 in the UK) for chest pain that comes and goes or is worse on breathing or coughing, feeling short of breath or too unwell for daily activities, or a cough with blood-stained mucus.
- A cough that lasts more than 3 weeks and is not improving, unexplained weight loss with a cough, or breathlessness that is getting worse instead of better.
- Extra care if you are over 65, pregnant, have a long-term condition such as lung, heart, kidney disease or diabetes, or have a weakened immune system: the NHS lists these groups as needing medical advice sooner.
- Symptoms that continue for months after COVID-19 (long COVID), such as breathlessness, exhaustion or brain fog: see a GP or healthcare provider.
About Support Respiratory Recovery After Illness
What this goal means
This goal is about the weeks after a respiratory illness such as a chest infection, bronchitis, pneumonia, flu or COVID-19, when the fever has gone but the lungs and body have not caught up. It covers what is normal, what supports healing and when something else may be going on.
It does not cover treating an infection, which needs a clinician when it is serious, or long-term lung conditions such as asthma and COPD, which are managed with medical care. It also does not repeat advice on the first return to work or school or on rebuilding fitness; those are on their own pages.
1,2Common experiences
A lingering cough is the most common experience. A review of studies of otherwise healthy adults with a sudden-onset cough illness found it lasted 17.8 days on average, while people surveyed expected it to last about a week. The NHS says bronchitis usually clears up in around 3 weeks, and that a cough usually settles in 3 to 4 weeks.
After pneumonia, most healthy people recover in one to three weeks according to the American Lung Association, and the NHS says most people feel better within 2 to 4 weeks; tiredness may take longer to lift. After COVID-19 the NHS says most people improve within a few weeks, though some people take longer.
Breathlessness on stairs, a tight or sore chest from coughing, poor sleep and a flat feeling are all common while you recover. The WHO lists feeling breathless, fatigue, poor sleep and low mood among the symptoms of post-COVID-19 condition, which is the term for effects that continue after the first illness.
3,1,4,2,5,6,7What affects recovery
Recovery tends to be slower with a more severe illness, an older age, smoking, pregnancy or a long-term health condition, and the NHS asks people in these groups to seek medical advice earlier. Not resting enough, returning to hard exercise too soon and breathing smoke or irritants may also slow things, although the sources we read do not measure these effects precisely.
Anxiety about breathing, poor sleep and low energy can feed each other. Doctors treat these as part of recovery rather than as something to push through.
1,2,7Related conditions
Pneumonia, bronchitis, flu, COVID-19 and long COVID are the illnesses this page follows on from. Persistent tiredness has several possible causes, including ME/CFS, anemia and thyroid problems, and is covered on its own page. We do not diagnose; a clinician can say what is behind symptoms that do not settle.
8,7Realistic expectations
Most people get back to normal with time, not with a special product. A short list of habits (fluids, rest, smoke-free air, gentle activity) has the best support. Some people have symptoms that last for months; the CDC describes long COVID as a chronic condition present for at least 3 months, and its advice is to talk to your healthcare provider if symptoms last for months.
Setbacks are common. If activity brings back symptoms, going back a step and building up more slowly is a sensible response rather than a failure.
9,8Who this applies to
Adults and older children recovering from a chest or respiratory infection who are otherwise healthy. People with asthma, COPD or another lung condition, people who needed hospital care, babies and young children, and anyone who is pregnant or has a weakened immune system should follow the advice of their own clinician, which may differ from the general steps here.

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
- Rest as needed, drink plenty of fluids and keep away from smoke and vaping.
- Note your start date and check in at 1, 2 and 3 weeks against the warning signs.
- Take short, easy walks and slowly add time, stopping if breathlessness or fatigue worsens.
Optional additions
- Warm honey drink for a cough (not for babies under 1).
- Sit upright and breathe slowly through your nose if you feel breathless.
- Ask a pharmacist which vaccines are recommended once you are well.
What to track
- Cough: better, same or worse; any blood or colored mucus.
- Breathlessness at rest and with activity.
- Energy, sleep and what makes symptoms better or worse (the NHS suggests a simple diary).
When to reassess
If your cough lasts more than 3 weeks without improving, breathlessness is getting worse, or you are still unwell after a few weeks, see a clinician. For symptoms that last months after COVID-19, ask about long COVID.
When to seek professional support
- Urgent care or emergency services for the warning signs above.
- Ask your GP about pulmonary rehabilitation or a long COVID service if symptoms linger.
- Ask about quit-smoking support if you smoke or vape.
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
Rest, fluids and giving it time
Moderate certaintyAddresses: Supports the body while the infection clears
Why it may help: The NHS advice for bronchitis and pneumonia is to rest, drink plenty of fluids and stay home if you have a fever or cannot manage normal activities. Cochrane reviewers also found that the natural course of an acute cough is longer than most people expect (17.8 days on average in one review), which is why patience is part of the plan.
How to apply it: Aim to drink enough that your urine is pale, rest when tired, and avoid judging recovery against the first week.
Who it may suit: Most people recovering from a short respiratory illness.
Precautions: Drinking a lot of fluid is not advised if a doctor has limited your fluids (for example with heart or kidney disease). Ask your clinician.
1,2,6,3Stay hydrated for daily wellbeing → Support recovery from common illness →
Smoke-free air (no smoking, no vaping, avoid smoke)
Moderate certaintyAddresses: Gives the airways a chance to heal
Why it may help: The NHS pages for bronchitis and pneumonia both say not to smoke during recovery, and the American Lung Association links quitting smoking to lower pneumonia risk.
How to apply it: Avoid smoking and vaping, and stay out of smoky rooms. Ask about quit support; there is a separate page for that.
Who it may suit: Anyone who smokes or vapes, or lives with someone who does.
Precautions: Stopping smoking is best done with support; never shaming. Talk to a pharmacist or doctor about options.
1,2,5Know the normal timeline and the red flags
Moderate certaintyAddresses: Avoids both needless worry and delay in getting care
Why it may help: Knowing that a cough often lasts about three weeks, and that the NHS asks you to seek advice for a cough lasting more than 3 weeks, blood in mucus, chest pain, breathlessness or severe symptoms, lets you recover calmly and still spot a problem.
How to apply it: Note the day your illness started, check in on day 7, 14 and 21, and compare symptoms with the warning signs above.
Who it may suit: Everyone, especially older adults and people with long-term conditions.
Precautions: If you are in a higher-risk group, seek advice earlier.
1,4,3Honey for a cough
Moderate certaintyAddresses: May ease cough in the first days
Why it may help: A Cochrane review of 6 trials with 899 children aged 12 months to 18 years found honey probably reduces cough frequency better than no treatment or placebo, with moderate certainty, mostly over the first days. A meta-analysis of 14 trials in upper respiratory tract infections found honey improved cough frequency and severity compared with usual care, but the trials comparing honey with placebo were mixed. The NHS suggests honey in a warm drink and says not to give it to babies under 1.
How to apply it: Stir honey into a warm drink and sip it. Studies used honey for a few days to a week; benefit beyond about three days was not shown against placebo in children.
Who it may suit: Children over 1 year and adults with a cough from a recent infection.
Precautions: Never for babies under 1 year. Contains sugar; consider if you have diabetes. It does not replace medical care for severe or lasting cough.
11,12,4,1Additional options
Sit upright and breathe slowly when breathless
Low certaintyAddresses: May make breathlessness feel easier to settle
Why it may help: The NHS COVID advice for breathlessness is to sit upright, lean slightly forward and breathe slowly through your nose. It is practical self-care advice rather than a trial result.
How to apply it: Sit on a chair, lean slightly forward with your arms resting, and breathe slowly in through your nose. Stop and seek help if breathing does not settle.
Who it may suit: Mild breathlessness during recovery.
Precautions: Breathlessness that is severe, sudden or does not ease is an emergency; do not rely on positioning.
6Gentle, graded activity
Low certaintyAddresses: Rebuilds stamina and eases fatigue
Why it may help: The NHS long COVID page suggests keeping a regular sleep and wake time and moving around or taking short walks if you can, stopping if symptoms appear. The WHO says energy conservation can help and activity should be reduced temporarily during a flare-up of symptoms.
How to apply it: Start with short, easy walks around the home or street, add time slowly, and rest when symptoms appear.
Who it may suit: People who are over the worst of the illness and have no new warning signs.
Precautions: The NHS says not to restart exercise for long COVID before speaking to a GP or specialist. People with chest pain, fainting or fast heartbeat should get urgent advice.
8,7Return to your routine after illness → Rebuild activity after illness →
Pacing and energy conservation
Low certaintyAddresses: Reduces setbacks when symptoms flare with effort
Why it may help: The WHO fact sheet says education about rest, sleep and energy conservation can help manage post-COVID symptoms. The NHS long COVID page notes symptoms can worsen with increased activity or stress. We did not find a trial of pacing for ordinary respiratory recovery.
How to apply it: Plan the day with rest breaks, spread out heavier tasks, and keep a diary of what makes you better or worse.
Who it may suit: People with lasting fatigue or breathlessness.
Precautions: If effort reliably brings on a crash lasting a day or more, ask a clinician about post-exertional malaise.
7,8Pace activity without overdoing it → ME/CFS and post-exertional malaise →
Vaccines when you are well again
High certaintyAddresses: May lower the chance of another chest infection
Why it may help: The NHS lists pneumococcal, flu, RSV and COVID-19 vaccines as ways to reduce the risk of infections that can cause pneumonia, with eligibility depending on age and health. The American Lung Association likewise says staying up to date with recommended vaccines such as flu and pneumococcal helps prevent pneumonia.
How to apply it: Ask your clinician or pharmacist which vaccines are recommended for you and when to have them after an illness.
Who it may suit: Adults and children who are eligible under local guidance.
Precautions: Timing after illness and eligibility should be confirmed with a clinician or pharmacist.
2,5Still being studied
Pulmonary rehabilitation after a flare-up of lung disease
High certaintyAddresses: Improves quality of life and may cut readmission in COPD
Why it may help: A Cochrane review of 20 trials (1,477 people) found rehabilitation after a COPD flare-up reduced hospital readmissions (moderate-quality evidence) and improved health-related quality of life (high-quality evidence), though effects on deaths were unclear. The NHLBI describes pulmonary rehabilitation as a supervised program of exercise, breathing techniques, education and counselling.
How to apply it: Usually arranged by a clinician as weekly sessions over several weeks. Not something to start alone after a simple cold.
Who it may suit: People with COPD or another chronic lung condition who have had a flare-up or hospital stay.
Precautions: Needs referral and supervision. Evidence is for COPD, not for recovery from a one-off infection in healthy people.
13,10Pulmonary rehabilitation for long COVID
Low certaintyAddresses: May improve exercise capacity, breathlessness and fatigue
Why it may help: A 2025 meta-analysis of 37 studies (3,363 people) found rehabilitation improved walking capacity, lung function, quality of life, fatigue, breathlessness and anxiety in long COVID, with 4 to 8 week programs combining breathing and multicomponent exercise looking most effective. An earlier review rated the certainty of evidence as very uncertain.
How to apply it: Programs are delivered by rehabilitation teams, often through a GP or long COVID clinic.
Who it may suit: People with symptoms lasting months after COVID-19.
Precautions: Study quality was mixed and many trials were small. Exertion can worsen symptoms in some people, so supervision is wise.
14,15,10Inspiratory muscle training
Low certaintyAddresses: May ease breathlessness after COVID-19
Why it may help: In a randomized trial of 281 adults about 9 months after COVID-19, 8 weeks of inspiratory muscle training did not change the main quality-of-life score but improved breathlessness scores, chest symptoms, respiratory muscle strength and estimated fitness. Many people withdrew.
How to apply it: Uses a hand-held device with a trained clinician's guidance.
Who it may suit: Adults with lingering breathlessness after COVID-19.
Precautions: One trial with a waitlist comparison, not a sham device. Not suitable for everyone, so ask a clinician first.
16Breathing exercises, yoga and qigong-style practices
Not enough evidenceAddresses: May ease breathlessness, anxiety and stress
Why it may help: A review of rehabilitation after COVID-19 found respiratory exercises and yoga seemed to reduce anxiety and depression, and qigong or acupressure programs seemed to reduce breathlessness, but the overall certainty was very uncertain.
How to apply it: Slow, gentle breathing practices taught by a qualified instructor or physiotherapist.
Who it may suit: People whose breathlessness has a tense or anxious component.
Precautions: Stop if you feel dizzy or breathless. Not a replacement for assessment of persistent breathlessness.
15Food & nutrition
Eating and drinking while you recover
The NHS advises drinking plenty of fluids when recovering from bronchitis, pneumonia and COVID-19 (enough to keep urine pale), and the NHS long COVID page suggests eating a balanced diet. We did not find in the sources we read any food shown to speed lung recovery.
Warm drinks can soothe a sore chest and throat. The NHS suggests honey and lemon drinks for a cough, with limited evidence of benefit, and honey is not for babies under 1. The NHLBI lists nutritional counselling as part of pulmonary rehabilitation, which can include meal planning and weight management for people with chronic lung disease.
1,6,8,4,10Foods and drinks that have been studied
Honey is the one food with human trials for cough in respiratory infections; see the What Helps tab.
Honey in warm drinks
Moderate certaintyAddresses: May ease cough over the first days
Why it may help: Cochrane review of 6 trials (899 children) and a meta-analysis of 14 trials in upper respiratory tract infections found honey improved cough compared with no treatment or usual care; trials against placebo were few and mixed.
How to apply it: Studied as honey given for a short time, from a few days to a week.
Who it may suit: Children over 1 year and adults with a cough.
Precautions: Not for babies under 1 year. Contains sugar.
11,12,4Remedies & supplements
Traditional use, laboratory findings and human trials are kept apart. "Natural" does not mean safe.
Honey
Moderate certaintyStudied form and route: Stirred into a warm drink
Intended outcome: Easing cough
Human evidence: A Cochrane review found honey probably reduces cough frequency in children over 12 months compared with no treatment or placebo (moderate certainty), and a meta-analysis found it improved cough and combined symptom scores versus usual care in upper respiratory infections.
Limits: Benefit beyond about three days was not shown against placebo in children. Placebo-controlled trials in adults were few.
Interactions and precautions: Never give to babies under 1 year. Contains sugar, which matters for diabetes. See a clinician if cough lasts over 3 weeks.
11,12,4Pelargonium (Pelargonium sidoides) extract
Low certaintyStudied form and route: Liquid herbal preparations, mentioned by the NHS as an option
Intended outcome: Easing symptoms of acute bronchitis
Human evidence: A Cochrane review found low-quality evidence that pelargonium extract may relieve symptoms in acute bronchitis in adults and children, with liquid preparations showing benefit and tablets not. Adverse events were more common with the extract, none serious.
Limits: Trials were small, investigator-initiated and there was suspicion of publication bias. Studies were of acute illness, not of recovery after it.
Interactions and precautions: Check with a pharmacist if you take other medicines, are pregnant or breastfeeding, or are treating a child. Products vary.
17,4Therapies & care
Established care for respiratory recovery starts with a clinician for anything severe or lasting: assessment of symptoms, treating infection when needed, checking whether follow-up is appropriate, and referral to rehabilitation or a long COVID service. Asthma and COPD care continues as prescribed.
GP or clinician review
High certaintyMedical assessment The NHS asks people to see a GP if a cough lasts more than 3 weeks, if they are losing weight for no clear reason, or if symptoms suggest long COVID. The clinician can check for causes other than the infection.
Who it may suit: Anyone with a lingering cough, breathlessness or worrying symptoms.
Precautions: Urgent symptoms should not wait for an appointment; use urgent or emergency care.
4,8,1Pulmonary rehabilitation
High certaintySupervised exercise and education program The NHLBI describes supervised exercise training, breathing techniques, education and counselling for people with lung disease. Evidence is strongest after COPD flare-ups.
Who it may suit: People with chronic lung disease, and some with long COVID.
Precautions: Needs referral and supervision; the NHLBI notes risks are few, such as rare muscle or bone injuries.
10,13,14Physiotherapy-led breathing training
Low certaintyBreathing and respiratory muscle training Breathing control and inspiratory muscle training have been tried for post-COVID breathlessness, with small improvements in breathlessness in one trial and mixed certainty overall.
Who it may suit: Adults with lingering breathlessness.
Precautions: Stop and seek advice if symptoms worsen.
16,15Long COVID services and rehabilitation
Moderate certaintyClinical care The WHO says rehabilitation can manage many symptoms and functional limits after COVID-19, and the CDC advises people with symptoms lasting months to see a healthcare provider to make a personal management plan.
Who it may suit: People whose symptoms last months after COVID-19.
Precautions: Access varies by region.
7,9What 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
Smoking and vaping during recovery
Moderate certaintyWhy: The NHS says not to smoke when recovering from bronchitis or pneumonia, and quitting lowers pneumonia risk over time.
Who it applies to: Anyone who smokes or vapes, or is around smoke.
Try instead: Ask about quit support and keep smoke away from your home.
1,2,5Ignoring red-flag symptoms
High certaintyWhy: Severe breathing difficulty, blue or grey lips, sudden confusion, coughing blood and persistent chest pain need urgent care.
Who it applies to: Everyone, especially older adults and those with long-term conditions.
Try instead: Use the warning signs on this page and call emergency services when they apply.
1,6Personal triggers to check
Pushing hard exercise too early
Low certaintyWhy: The NHS long COVID advice is to be cautious with exercise and to speak to a GP or specialist before restarting it; the WHO says to reduce activity temporarily during a flare-up. Symptoms may worsen with increased activity.
Who it applies to: People with lingering breathlessness, fatigue or long COVID.
Try instead: Build up in small steps and stop when symptoms appear.
8,7Smoke, fumes and dust while healing
Not enough evidenceWhy: We did not find a study on irritants and recovery speed in the sources we read, but the advice to avoid smoke during recovery is consistent across the NHS pages.
Who it applies to: People with a cough or breathlessness.
Try instead: Choose fresh air, and see the irritants and indoor air pages.
1Reduce exposure to respiratory irritants → Improve indoor air quality →
Products that need caution
Cough medicines for a chesty cough from pneumonia
Moderate certaintyWhy: The NHS pneumonia page says to avoid cough medicine because coughing helps your body get rid of the infection. A Cochrane review of over-the-counter cough medicines in children and adults found limited evidence of benefit.
Who it applies to: People recovering from pneumonia or chest infections.
Try instead: Talk to a pharmacist; honey in a warm drink is a gentler option.
2,18Heated humidified air or steam as a cure
Low certaintyWhy: A Cochrane review found no clear benefit or harm for heated, humidified air in the common cold, and some people reported nose irritation.
Who it applies to: Anyone tempted by steam or inhalers.
Try instead: If you like it for comfort, take care with hot water, especially around children.
19Unsupported claims
Claims of lung detox or cleansing
Not enough evidenceWhy: We did not find a human trial in the sources we read showing that a supplement, tea or product detoxes or cleans the lungs after illness. The lungs clear themselves, and the NHS advice centers on fluids, rest and smoke-free air.
Who it applies to: Anyone offered a lung detox product.
Try instead: Spend effort on proven basics and ask a pharmacist before buying products.
2,1Common mistakes
Expecting the cough to vanish in a week
Moderate certaintyWhy: Surveyed adults expected a cough to last about a week, but studies found it averaged 17.8 days.
Who it applies to: People recovering from acute cough illness.
Try instead: Plan for about three weeks and see a clinician if it lasts longer.
3,1Stopping prescribed antibiotics or inhalers early
High certaintyWhy: The NHS says to finish a prescribed antibiotic course even if you feel better and to contact your doctor if you have not improved after 2 to 3 days. Never stop an inhaler or other medicine without asking your prescriber.
Who it applies to: Anyone on prescribed treatment.
Try instead: Take medicines as prescribed and ask the prescriber or pharmacist if you have concerns.
2Giving honey to infants
High certaintyWhy: The NHS says not to give honey to babies under 1 year old.
Who it applies to: Parents and carers.
Try instead: Ask a pharmacist or doctor about a cough in a baby; a floppy or unresponsive baby is an emergency.
1,4Evidence & safety
What the research shows
Health agencies agree on a few basics for respiratory recovery: rest, fluids, no smoking, patience about how long a cough lasts, and knowing the warning signs. Honey has the best trial evidence for cough, pelargonium has low-quality evidence, and rehabilitation has good evidence after COPD flare-ups and uncertain evidence after COVID-19. Most other natural options have little or no human evidence for recovery.
Limits of the evidence
- Many trials studied the acute illness, not the recovery period afterwards.
- Rehabilitation trials after COVID-19 were mostly small, varied in design and rated as uncertain.
- Cough duration figures come from otherwise healthy adults and children and may not apply to people with lung conditions.
Precautions and interactions
- Herbal products can interact with medicines; ask a pharmacist, especially if you take prescribed treatment.
- Do not stop or replace prescribed inhalers, antibiotics or other medicines because of anything on this page.
- Hot drinks and steam can scald; keep them away from small children.
Life-stage considerations
- Babies and children: honey is not for babies under 1 year; a baby who is floppy, unresponsive or struggling to breathe needs emergency care.
- Pregnancy and breastfeeding: the NHS lists pregnancy as a reason to seek medical advice early; herbs and supplements are mostly unstudied, so ask a clinician.
- Older adults and people with long-term conditions or weakened immunity: seek medical advice sooner and do not self-manage a worsening cough.
Warning signs
- Severe breathing difficulty, unable to speak, pale, blue or grey lips or skin, or sudden confusion.
- Coughing up blood or blood-stained mucus, or chest pain that comes and goes or happens with breathing or coughing.
- A cough lasting more than 3 weeks, unexplained weight loss, or breathlessness getting worse.
- Low mood or anxiety that is hard to cope with: speak to a doctor.
Claim checks
Honey is as good as medicine for post-infection cough
Moderate certaintyHoney probably helps cough over a few days compared with no treatment or placebo in children, but evidence against placebo in adults is limited and it is no replacement for medical care.
11,12Steam inhalation clears chest infections
Low certaintyA Cochrane review found no clear benefit or harm of heated humidified air for the common cold; we did not find evidence it treats chest infections.
19A herbal tea or supplement will detox your lungs
Not enough evidenceWe did not find human trials showing lung detox effects in the sources we read.
2Cough medicine helps pneumonia coughs
Moderate certaintyThe NHS advises avoiding cough medicine in pneumonia because coughing helps clear infection.
2,18Exercise is always good during recovery
Low certaintyGentle movement is encouraged, but the NHS and WHO advise caution, stopping when symptoms appear and reducing activity during flare-ups.
8,7Questions people ask
How long does a cough last after a chest infection?
A review of studies in otherwise healthy adults found a cough lasted 17.8 days on average. The NHS says bronchitis usually clears up in about 3 weeks, and see a doctor if a cough lasts longer or is not improving.
Is it normal to feel breathless while I recover?
Mild breathlessness with effort can be part of recovery, and the WHO lists feeling breathless among post-COVID symptoms. Severe or worsening breathlessness, or being unable to speak, needs urgent care.
When should I see a doctor?
The NHS advises seeing a doctor for a cough lasting more than 3 weeks, chest pain, coughing blood, feeling short of breath or too unwell for daily activities, or if you are over 65, pregnant, or have a long-term condition or weak immunity.
Does honey really help a cough?
A Cochrane review found honey probably reduces cough better than no treatment or placebo in children over 12 months, mainly over a few days. Do not give it to babies under 1 year.
Should I take cough medicine after pneumonia?
The NHS says to avoid cough medicine with pneumonia, because coughing helps your body clear the infection. Talk to a pharmacist or doctor.
When can I go back to exercise?
Start with short, easy walks and build slowly, stopping if symptoms appear. For long COVID the NHS says to speak to a GP or specialist before restarting exercise. See our pages on returning to your routine and rebuilding activity.
What is pulmonary rehabilitation?
The NHLBI describes it as a supervised program of exercise, breathing techniques, education and counselling for people with lung disease. Evidence is strongest after COPD flare-ups; ask your doctor if it suits you.
Are herbs or supplements useful for lung recovery?
Pelargonium has low-quality evidence for acute bronchitis symptoms; most other options have little human evidence for recovery. Check with a pharmacist, especially if you take medicines or are pregnant.
Does smoking or vaping matter while I recover?
The NHS says not to smoke when recovering from bronchitis or pneumonia. Support is available if you want to stop.
What if symptoms last for months after COVID-19?
The CDC describes long COVID as present for at least 3 months and advises talking to a healthcare provider. The WHO says rehabilitation can help many symptoms.
Can vaccines help?
The NHS lists pneumococcal, flu, RSV and COVID-19 vaccines as ways to reduce the risk of infections that can cause pneumonia, subject to eligibility. Ask a clinician or pharmacist what is recommended for you.
