Repeat if necessary. If you have an abnormal amount of mucus and are having trouble getting the mucus up, there are other methods, beside learning to cough effectively, to help you. First, drink 8-10 glasses of water every day. Water will thin out the mucus and therefore make it easier to cough up. After several days of drinking extra water, you'll be ready for postural drainage.
Postural drainage is a method that used gravity and body positioning to help remove secretions.
Do this at least twice a day and more often if you can. Try to do it before meals and before bedtime. Wear light clothing because it can hurt if it is done over bare skin. Check with your doctor before using postural drainage and chest physical therapy.
