Take a deep breath and hold your breath for more than 10 seconds. If you complete it successfully without coughing, without discomfort, stiffness or tightness, etc., it proves there is no Fibrosis in the lungs, basically indicates no infection. In critical time, please self-check every morning in an environment with clean air.
Serious excellent advice by Japanese doctors treating COVID-19 cases: Everyone should ensure your mouth & throat are moist, never dry.Take a few sips of water every 15 minutes at least. Why?

If you don'tdrink enough water more regularly, the virus can enter your windpipe and into the lungs.
