ELI5:Why is it beneficial to "breath in through your nose and out through your mouth"
gpt
It is a good way of psychologically getting someone to clam down.

You would actually lower youre heart rate faster by breating in and out through you're mouth slowly, (you wouldn't see an athlete attempting to breath in nasally near the end of a race it would have no benefit) but by telling someone to breath in through nose and out through mouth, you're easily getting them to concentrate on their breathing which can help calm them down, and thus feel better if they were previously in a paniced state!
