Disclaimer: I am not advising anyone on how to treat their problems. This is purely an FYI on how to treat some people with these issues.
Postural drainage is done by positioning your body so that your head is lower than your chest. This allows mucus to drain better from the bottom of your lungs. Postural drainage is one way to help treat breathing problems due to swelling and too much mucus in the airways of the lungs. Chest physical therapy or postural drainage and percussion, uses gravity and percussion (clapping on the chest and/or back) to loosen the thick, sticky mucus in the lungs so it can be removed by coughing. Unclogging the airways is key to keeping your lungs healthy.
With ongoing flu and emerging virus, most deaths are from infected mucous filling lungs. Nearly a hundred years ago, physical therapists began using gravity to help clear lungs, saving lives from flu & pneumonia, and helping other COPD issues. Simply position yourself to orient bronchial tubes to gravity-drain. Pic above shows simplified method…
During this, perform a few pursed-lip blows: inhale only to just half-fill lungs, then purse lips as if blowing out a candle and exhale. As long as you can to totally empty lungs.
Do three of these. Spend 2-3 minutes in each position. Junk will gravity-flow high enough to cough up… and it can be a mess (you want that).
