I've been doing abit of research on the net and I've found that to breath properly and for breathing to be more beneficial for your body you should breath in and out through your nose and rarely through your mouth. Is this true?
When I was a child I used to get quite bad nose bleeds and so would get wary about breathing through my nose, so if you are meant to breath through your nose, I've been doing it wrong all my life.
I've had a go at breathing in and out through my nose just and it makes me go slightly light headed? Is this because I'm getting more oxygen than what I'm used too?
I would be grateful if someone could give me more information on breathing properly and so tips for doing so.
