Stay Away From Smoke
Cigarette smoke can make your symptoms worse. So stay away from others who light up. And if you smoke, this is the time to quit. Smoking makes you more likely to get pneumonia or other lung problems in the future. Another tip: Even though a warm fireplace might feel cozy, you should avoid it and any other areas where the air might not be clean.
Exercises for Your Lungs
Breathing exercises can give your lungs a boost as you get over pneumonia. Take five to 10 deep breaths, then cough forcefully two or three times. That should push some mucus out of your lungs. Or just take slow, deep breaths. Another exercise to try: Blow through a straw into a cup of water.
