When I was in my early 20's my GF at the time discovered I wasn't breathing for lengthy periods. She said she counted slowly to 30 and could stand it no longer so she moved or figgeted or jigged and I would take a deep breath. I think I did snore too.
This happened to be early in the night and I was just falling asleep, right on the cusp. So for a few nights I was unimpressed with her antic's
I didn't think anything of it as work was physically hard and I was generally active anyway- cycling(daily), bushing walking (with the dog, so regularly), visiting the beach (with my young cousins) were some of the norm's. Diet was usually good. I just figured my body was relaxing.
I honestly don't know if I still do anything like that during sleep, the wife hasn't said anything
I think stuff like this has always been around, possibly more so nowadays with the easy life (unhealthy lifestyes) and also with doctors and the big pharma's coming up with more ways to make people think they are unwell (don't take offence to that). What surprises me most is you people that have just posted come across like you are active and healthy, so why do you have sleep apnea? Is it really just age related?
