One of the great things about a lung exercise device like Breathe and GO is that it is 100 percent drug-free and can be used by people of all ages, from two years to 100 years.
Now, a drug-free lung exercise device is helping to combat the deadly effects of both indoor and outdoor air pollution. The Breathe & GO lung exerciser is a hand held medical device that helps clear the lungs of mucus.
First of all, spend a reliable period of time outside of polluted city areas. Forest, sea, ocean, just not cities.
Second, pleuresy is an infection, thus what you should be focusing on is the quality of your immune system.
The immune system can be stimulated through meditation, breathing exercises, physical exercise, proper nutrition (lots of vegetables, little to no ammount of processed foods, if you must eat meat, eat lean).
I absolutely recommend you find crystallized vitamin C (100+g bottles) and soy lechithin, and mix up a spoonful of each every day (even twice a day) with some clear spring water and drink it.
In your case, DO NOT FORCE the breath. Yes, do the lung exercises, but as slowly and relaxed as possible. You don’t want to hurt yourself any further.
And I know this is 6 months old, but maybe it may still help.
Health professionals and researchers are continuing to discover the huge benefits of regular lung exercises for those who suffer from COPD and other similar respiratory lung conditions, like asthma, cystic fibrosis, bronchitis, and even sleep apnoea and the common cold and flu.
