What are the best ways to breathe?

Answer 1

We are told at school to breath through your nose, hold it for 3-5 seconds, and exhale through your mouth. This way it brings oxygine through the lungs, and blood to your brain. You don't necessarily need to hold your breath for 3-5 seconds. Whatever feels more comfortable for you. When running or exercising it is always best to breath in your nose and out the mouth.
