Exercise daily to keep your body and immune system strong. Stretch your ribs to increase lung capacity. Stand upright with your back arched and exhale all the oxygen from your lungs. Breathe in slowly, filling your lungs as much as possible and hold your breath for at least 10 seconds. Slowly exhale.
It is best to avoid eating raw or uncooked foods like salad and sushi; greasy or fried foods like chips, fries, and cheese; and pungent or heavily seasoned foods like kimchi, curries, and barbeque. No chocolate. No smoking, alcohol, coffee and cold beverages.
