Asthma: Prevention

Vaccinations

Due to the increased risk of complications, people with severe asthma are recommended to receive vaccinations for influenza (flu) and pneumococcal (a bacterium that can cause pneumonia, meningitis and infection of the blood).

Smoking     

If you are a smoker and you have asthma, you should stop smoking. This will significantly reduce the severity and the frequency of your symptoms. Smoking can also reduce the effectiveness of asthma medication. Your doctor or pharmacist will also be able to provide you with help and advice. If you do not smoke and you have asthma, you should still avoid exposure to tobacco smoke.

Avoiding triggers

It is important that you identify triggers where possible, by making a note of any worsening symptoms or by using your peak flow meter during exposure to certain situations. Some triggers, such as air pollution, viral illness or certain weather conditions, can be hard to avoid. However, it may be possible to avoid other triggers, such as dust mites, fungal spores or pet fur.

Weight, diet, and exercise

Maintaining a healthy weight will help you to control your asthma more effectively. The key to maintaining a healthy weight is having a healthy diet and taking regular exercise. A low fat, high fiber diet is recommended, including plenty of fresh fruit and vegetables (five portions a day) and whole grains. Thirty minutes of moderate exercise a day, three times a week, is also recommended. The exercise should be vigorous enough that it leaves your heart beating faster and you should feel slightly out of breath. Examples of moderate exercise are going for a brisk walk and Curves program.

If your asthma is well managed, moderate exercise should not normally cause any problems. However, see your doctor if you experience symptoms of asthma during or after exercise.
