What You'll Learn
Stop smoking and avoid other pollutants
One of the best ways to keep your lungs healthy is to stop smoking. Cigarette smoking is the leading cause of lung cancer and chronic obstructive pulmonary disease (COPD). It causes chronic inflammation and swelling in the lungs, which can lead to chronic bronchitis. Over time, cigarette smoke destroys lung tissue and may trigger changes that result in cancer. Stopping smoking can reduce your risk of at least 16 types of cancer, including lung cancer, and lower your risk of lung and heart conditions such as heart attack, stroke, and COPD.
Quitting smoking can be challenging, but it is a highly rewarding decision for your health. It is never too late to benefit from quitting. Your lungs will begin to improve once you stop smoking, as they are self-cleaning organs that can heal themselves by producing mucus to trap and remove unwanted substances. You can also seek medical advice and support to manage withdrawal symptoms. Your doctor can recommend stop-smoking medications, such as nicotine replacement therapy (NRT), which provides nicotine without the harmful chemicals in tobacco smoke. NRT is available in various forms, including nasal sprays, gums, and patches, and can be prescribed or purchased over the counter. E-cigarettes or "vapes" are another option, delivering nicotine in a vapour form without the tobacco. Combining stop-smoking treatments with specialist advice from free local smoking cessation services can increase your chances of success.
In addition to quitting smoking, it is essential to avoid exposure to other pollutants that can harm your lungs. This includes indoor and outdoor air pollution. To improve indoor air quality, ensure proper ventilation and regular cleaning of your living and working spaces to prevent the buildup of allergens, dust, and mould. Avoid using strong cleaning fluids and aerosols, and refrain from burning solid fuels like wood for heating or cooking. Regarding outdoor air pollution, check the Air Quality Index before engaging in outdoor activities and try to avoid heavy traffic when possible. Regular health check-ups are also recommended to detect any lung conditions early on, as they may go unnoticed until they become more serious.
By taking these steps to stop smoking and avoiding other pollutants, you can significantly improve your lung health and overall well-being.

Exercise regularly
Regular exercise is key to keeping your lungs healthy. Physical activity can help strengthen your heart and lungs, allowing them to work more efficiently. It may also reduce your risk of lung injury or disease. When you are physically active, your heart and lungs work harder to supply the additional oxygen your muscles demand. Just like muscles in your body, regular exercise makes your lungs and heart stronger.
You should aim to be active every day, even if it's just a small amount of movement. Start with a level that's right for you and slowly increase the intensity and duration over time. National guidelines recommend that all adults get at least 30 minutes of moderate physical activity, five days a week. This could include activities such as brisk walking, recreational cycling, or vigorous house cleaning. If you are unsure about what type or amount of activity to do, consult a healthcare professional for advice.
If you are cycling, jogging, or walking outdoors, try to maintain a safe distance from busy roads to reduce your exposure to air pollution. You can also consider exercising indoors in a gym or at home, but be mindful of potential indoor air pollutants such as cleaning product fumes and air fresheners. It is important to consider the impact of air quality on your lungs during exercise, as physical activity increases the amount of air you breathe in, allowing particles to penetrate deeper into your lungs.
Overall, regular exercise is a great way to keep your lungs healthy, but be sure to work at a comfortable pace and consult healthcare professionals if needed.

Improve indoor air quality
Improving indoor air quality is essential, as the air we breathe indoors can be even more polluted than outdoor air. Here are some ways to improve the air quality inside your home:
Ventilation and Fresh Air
Opening doors and windows for at least 10 minutes daily can help improve indoor air quality. This simple, no-cost solution allows fresh outdoor air to dilute indoor pollutants, making it healthier to breathe. However, if you live near a busy road, factory, or other sources of outdoor air pollution, opening windows may not be advisable. In such cases, consider using a portable mechanical HEPA air purifier to capture pollutants.
Regular Cleaning and Dusting
Keeping your indoor space clean is crucial for improving air quality. Vacuuming carpets and rugs at least once or twice a week with a HEPA filter vacuum can effectively reduce dust, allergens, and pet dander. Additionally, use a microfiber or damp cloth for dusting to trap dust particles and prevent them from becoming airborne. Regular cleaning can also help prevent the buildup of mold and mildew, which can be triggered by humidity.
Avoid Indoor Allergens and Irritants
Indoor plants, while aesthetically pleasing, can foster the growth of mold and trigger allergies. If you are sensitive to allergens, it is advisable to keep greenery outdoors. Similarly, avoid using strong cleaning fluids and aerosols, as these can release fumes that contribute to indoor air pollution.
Change Air and Appliance Filters
Changing the filters in your forced-air heating system and other appliances regularly is essential for trapping dust, allergens, and other airborne irritants. Electrostatic filters are particularly effective in capturing these particles and preventing them from recirculating in your indoor space.
Reduce Exposure to Combustion By-Products
Burning fuel for cooking, heating, or drying clothes can release harmful emissions, such as carbon monoxide and benzene. Ensure that your appliances are properly installed and vented to direct these combustion by-products outdoors. Additionally, avoid burning solid fuels like wood, as this can contribute to indoor air pollution.
By implementing these measures, you can significantly improve the indoor air quality and create a healthier living environment for yourself and your family.

Adjust your diet
While it is important to avoid exposure to harmful pollutants, it is also crucial to adopt a healthy diet that can help your body cope with the adverse effects of air pollution on your lungs. A well-balanced diet can provide your body with the necessary tools to fight against these pollutants and keep your lungs functioning optimally.
Firstly, focus on including a variety of vitamins and nutrients in your meals. Vitamins A, C, D, and E are essential for maintaining lung health. Vitamin E, in particular, is considered a powerful defence mechanism against various pollutants, helping to prevent injuries to human tissues caused by air pollution. Vitamin C, found abundantly in plant-based cooking oils like rice bran oil, sunflower oil, olive oil, and canola oil, is another crucial component of your diet. Consuming almonds and sunflower seeds will also provide you with these essential vitamins.
Additionally, incorporate anti-inflammatory foods into your meals. Spinach, kale, methi, mustard greens, and other leafy greens are excellent choices. These vegetables are rich in Beta carotene, a beneficial nutrient that safeguards your body from harmful air pollutants that can damage your lungs. Radish and carrots are also recommended for their ability to protect your body from the impact of air pollution on your heart and lipid profile.
Nuts and seeds, such as chia seeds, flaxseeds, and walnuts, are also beneficial additions to your diet. These provide a good source of Omega-3 fatty acids, which have anti-inflammatory properties. Including fish in your meals can also contribute to reducing inflammation in the body.
While adjusting your diet, it is essential to avoid certain foods that can have adverse effects on your lungs. Processed or cured meats, excessive alcohol consumption, sugary drinks, and an excess of salt are some of the dietary choices that may negatively impact your lung health.

Get vaccinated
Vaccines are an effective way to protect yourself from respiratory diseases and keep your lungs healthy. Vaccines work by imitating an infection, which causes your immune system to produce antibodies, helping your body to recognise and fight the real disease. This reduces your chances of getting sick and prevents the spread of the disease to others.
Getting vaccinated is especially important for people with lung conditions or other health conditions, as they may be at a higher risk of developing serious lung infections. It is recommended that individuals with lung disease, such as asthma or COPD, stay up to date with their vaccinations to protect themselves from vaccine-preventable diseases.
There are several vaccinations that are important for maintaining lung health. These include:
- COVID-19 vaccine: This vaccine protects against severe COVID-19 illness, which can cause respiratory complications.
- Influenza vaccine: Getting a flu shot every year protects against seasonal flu, which is a respiratory infection.
- Pneumococcal pneumonia vaccine: This vaccine protects against the most common type of bacterial pneumonia, which can cause lung infection.
- Pertussis (Whooping Cough) vaccine: This combination vaccine also protects against tetanus and diphtheria, and can help prevent respiratory complications.
It is important to consult with a healthcare professional to determine which vaccines are recommended for you and when you should receive them. Staying up to date with vaccinations is a crucial step in maintaining lung health and preventing the spread of infectious diseases.
