Lung capacity is one of the most important measures of our health, and one that tends to decline with age. It is usually at its peak in our mid-twenties, and decreases slightly each decade after that. However, there are things you can do to foster better lung capacity. Here are a few tips to improve your respiration.

Assess your air quality

In some ways, your lungs are only as good as the air they breathe. Assess the quality of air around you, both at work and at home. Things like excessive perfume, mold and dust can reduce air quality. See if you can use an indoor air filter if reducing these pollutants is not possible.

Eat right

Antioxidant-rich foods help bring more oxygen to the lungs. Try adding more of them to your diet. Tasty options include berries, dark chocolate, plums and nuts .

Exercise

Lungs function better when they’re given a regular “workout.” This can include anything from a brisk hike to running a marathon. Increase your exercise habits according to your fitness level, and you may notice you become less breathless over time.

Quit smoking

Smoking instantly reduces lung capacity, and can lead to lung diseases over time. If you smoke, make an effort to quit, and try to avoid secondhand smoke.
