I find it easier to use the mouth to breathe both in and out
Is there a difference?
Thanx

Yes. Open mouth breathing makes it easier for the opponent to knock you out, break your jaw, and make you bite your own tongue.

Breathing through your nose is more efficient and healthier than breathing through your mouth. Not to mention you won't look like a fish out of water.

It takes a while to get used to breathing through the nose if you're naturally a mouth breather, but it's worth it.

Breathing through the nose also allows the hairs to properly filter the air and the blood vessels/mucous membrane to properly moisten the air and get it to the right temperature. It prevents respiratory infection and bronchitis.

I didnt know any of that.

cool.

If you breath out of your nose during cold season you end up with snot all over your face:)
More important -where are you brething from-the chest or the belly?

..the lungs I think lol

More amazingly you can dramatically increase your cardiovascular endurance through nose breathing.

Choose an exercise eg running or cycling and only breathe through your nose. When you get to a point where you feel you need to breathe through your mouth then SLOW DOWN to a point where you need only breathe through your nose again. Gradually you will find you can go faster and faster nose breathing only and more quickly than you think you will be exercising at the same intensity you used to with a major difference - your perceived exertion will be much lower ie you will find that you can run at your old speed with virtually no apparent effort. Instead of puffing away it will seem like a walk in the park.

Nose breathing rules ok.
