You can take steps to make sure you are not in an environment that adds stress to your lungs.
Avoid anything that irritates your lungs, nose, mouth, larynx or windpipe. These include tobacco smoke, ozone, sulphur dioxide, nitrogen oxides, paint fumes, automobile exhaust, some cooking odors and perfumes, hair spray, dust, cold air, and extremely humid or dry air.27
Keep the humidity level in your home at 40% to 65%. Change furnace and air conditioner filters frequently.28
Wear a soft scarf or a cold air mask (available from a pharmacy) over your mouth and nose to warm the air as it enters your lungs. Breathe through your nose because it helps warm up the air as it travels to your lungs. It also prevents spasms of the bronchial passages.
Get a pneumonia vaccination as advised by your doctor and an annual flu shot. Avoid direct contact with people who have a cold or the flu. Make sure that you and your caregivers wash your hands often. Most infections are spread by hand contact.10
