Another question from this newbie. I've been reading about the pursed lip breathing technique and realise it's something I've been doing for quite a while (months before I was diagnosed).
I read you should breathe in through your nose - 1,2, and breathe out through your mouth - 1, 2, 3, 4.
Is it important that you should breathe in through your nose? I tend to breathe in through my mouth and during this cold weather I usually have a scarf wrapped round my mouth so the air I breathe in isn't very cold.
