Is Nasal Breathing Your First Line of Defense
* The mechanism of Covid-19 remains unknown and it is not known if breathing through the nose can inhibit this virus.
* However, it is logical to breathe only through the nose given that the primary defense to airborne viruses is in the nose and not the mouth, that breathing through the nose can support the body’s natural resistance to infection.
* Breathe through your nose, especially in public places- traveling on bus, train, exercising in the gym, etc.
* Be aware of your breath-hold time during rest. During a head cold, lower respiratory tract infection or respiratory symptoms, a breath-hold time during rest is reduced. To test, exhale through the nose, hold breath and time how long it takes for you to experience the first definite desire to breathe. If it is less than 10 seconds, then respiration is labored.
