My friends & familyhave for a number of months keep pointing out that my breathing has become really bad.

I have been told that I have very shallow breaths & when I'm eating my friends & family keep pointing out that I am strugling to breath so much when I am eating food that I have to stop chewing & open my mouth to catch a breath.

My friends & family also keep pointing out that I am always huffing & puffing & that I seem to be always out of breath where ever I go.

Lastly my girlfriend doesn't like spending the night at mine as when I am a sleep I snore really loudly & during the course of the night if often sounds like I choking & gasping for air & she keep thinking I'm going to die.

My girlfriend bought me a box of nose strips that widen your nostrils. I have tried these but they have not really helped at all.

So I was wondering if any user on here knows;

1. Any methods or exercises that increase the depth of breath when breathing.

2. Any methods or exercises that help increase the size of ones lung capacity.

3. Any methods or exercises that improve the lungs performance in its ability to asorb more oxygen with each intake of air.

4. Any methods or exercises to improve lungs strength & stamina.

5. Any methods or exercises that help you hold your breath longer.

6. Anything that can help improve breathing when one is a sleep.

Many Thanks
