Answer 1

One thing that hasn’t been mentioned about why you should breath through your nose and not your mouth.
Hyperventilating.
You can breath much more air faster through your mouth. Which would be good except in a panic attack.
Every breath out you get rid of carbon dioxide. Which is good if you have too much because of exercise. But it’s acidic when in your blood. But you need some to help keep your blood acidity in balance.
When you panic breath through your mouth it blows out too much CO2 and screws up your blood chemistry. Which is then also bad for you.
