eli5: why do most, if not all, breathing techniques specify ‘out through the mouth’?

1.12K views

i can understand in ‘through the nose’, since dust and other bits can be blocked by the nose hairs and mucus, and apparently the air is more likely to warm up when passing through the nose first, reducing irritation of the throat.

but what difference, if any, does exhaling through the mouth make?

Oxygenation and muscle engagement.

Breathing in through your nose in addition to all the benefits you listed, also increases the amount of oxygen you get by like 20%. When you exhale through your mouth it encourages engaging your diaphragm more than through your nose.

These things together, activating muscle groups and oxygenating your blood, prepare your body for physical activity. For some reason our brains also tend to increase focus and reduce drowsiness for it as well.

Short deep breaths, long focused breaths, pulsed breathing, they’re all looking for a response to breathing patterns present in other activities

Along with what others have said, it can help you exhale more CO2. We do this a lot with our COPD patients where we have them inhale through their nose and exhale through mouth like they’re blowing through a straw. This slows down the rate of exhalation allowing more CO2 to diffuse out of the bloodstream.

So, I usually breath in and out through my nose. Should I make a habit of exhaling through the mouth?
