Looking After Your Lungs: Everyday Prevention and When to Get Checked

Your lungs work every minute of every day, and most of the time you do not have to think about them. But lung health can decline quietly over many years, and the habits you build now make a real difference later in life.

Many of the biggest risks to your lungs can be reduced. Stopping smoking, staying active, getting vaccinated and recognising symptoms early all help.

This page brings together practical steps to protect your lungs and explains which symptoms should be checked by a GP.

Why lung health matters

Healthy lungs help you stay active and independent and recover more easily from infections. Lung conditions are one of the main causes of ill health in the UK, and many develop slowly. Common long-term lung conditions include:

asthma
COPD
bronchiectasis
lung cancer

Many of these are easier to manage when they are recognised early, which is why persistent symptoms are worth checking.

The biggest risks to your lungs

Smoking is the most important avoidable cause of lung disease in the UK. Other risks include second-hand smoke, air pollution, dusts and fumes at work, and repeated chest infections.

Some risks, such as family history or inherited conditions, cannot be changed. But reducing the ones you can control lowers your overall risk.

Everyday steps to protect your lungs

Small, consistent habits add up:

Do not smoke

Stopping smoking is the single most effective step for lung health, at any age. Avoid second-hand smoke where you can.

Keep active

Regular activity that leaves you a little out of breath helps keep your heart and lungs fit.

Get vaccinated

Flu, COVID-19, pneumococcal and RSV vaccines help protect against serious chest infections, if you are eligible.

Reduce indoor pollution

Ventilate your home, especially when cooking, and deal with damp and mould.

Protect yourself at work

Use the protective equipment provided if you work with dusts, fumes or chemicals.

Limit outdoor pollution

On high pollution days, consider quieter routes and less strenuous outdoor exercise, especially if you have a lung condition.

GP advice on lung symptoms not to ignore

Symptoms you should not ignore

See a GP if you notice:

a cough that lasts more than three weeks
breathlessness that is new or getting worse
repeated chest infections
wheeze or chest tightness
unexplained weight loss or tiredness

These symptoms often have a simple cause, but it is important to get them checked, especially if you smoke or used to smoke.

Online GP discussing urgent breathing symptoms

Urgent symptoms

Some symptoms need prompt or urgent attention:

coughing up blood
chest pain
sudden or severe breathlessness

Call 999 or go to A&E if you have severe breathlessness or chest pain, cannot speak in full sentences, or your lips look blue. Coughing up blood should always be assessed urgently.

Vaccines and lung health

Vaccines are one of the simplest ways to protect your lungs. Depending on your age and health, you may be offered:

the yearly flu vaccine
COVID-19 vaccines
the pneumococcal vaccine
the RSV vaccine, for some older adults and in pregnancy

Eligibility can change from year to year. Your NHS GP practice or pharmacy can tell you which vaccines you are due.

Exercise and breathing

Being active is good for your lungs, even if you have a lung condition. It helps to:

build up gradually
choose activities you enjoy, such as walking, swimming or cycling
follow any advice in your asthma or COPD plan about exercise

Feeling a bit out of breath during activity is normal. If you are much more breathless than you would expect, or it is getting worse, speak to a GP.

NHS lung health checks

The NHS in England invites some people aged 55 to 74 who smoke or used to smoke for a lung health check, as part of targeted lung cancer screening.

you will be contacted if you are eligible
the check starts with a conversation about your lung health
some people are then offered a low-dose CT scan

If you are invited, it is worth taking part. If you are not eligible but have symptoms, do not wait for a check: see a GP.

Living with a lung condition

If you already have a lung condition, staying well means:

taking your treatment as prescribed
having regular reviews
knowing your personal action plan
seeking help early when symptoms change

Our guides to asthma in adults, COPD and inhaler technique explain more.

Frequently asked questions

How can I improve my lung health?

Not smoking, staying active, getting vaccinated when eligible, reducing exposure to pollution and dust, and getting symptoms checked early are the most effective steps.

When should I see a GP about a cough?

See a GP if your cough has lasted more than three weeks. Seek urgent advice if you are coughing up blood, have chest pain or are increasingly breathless.

Does exercise help your lungs?

Regular activity improves fitness and helps your heart and breathing muscles work more efficiently. It is beneficial for most people, including many with lung conditions.

Which vaccines protect the lungs?

Depending on your age and health, the flu, COVID-19, pneumococcal and RSV vaccines can help protect against serious chest infections.
