Eat light meals and keep your environment clean. Wash your hands often. It is best to avoid eating uncooked and cold foods like salad, sushi, smoothies, and ice cream; greasy or deep fried foods like chips, fries, and cheese; and pungent or heavily seasoned foods like kimchi, curries, and barbeque. No shrimp and shellfish. Avoid chocolate. No smoking, alcohol, and coffee.
Exercise daily to keep your body and immune system strong. Practice deep breathing using your nose not your mouth. Wear clothing that covers your chest to protect your lungs especially if it is windy and cold.
