Hi all, I'm new here and wondered if anyone could answer a question for me.
I've had problems sleeping for many years so when I heard about breathing techniques guaranteed to get you to sleep.... well I had to try one! It worked and I was asleep within minutes. But what's worrying me is that they work by cutting down the volume of oxygen in the blood and as a copd sufferer my normal level of oxygen is only 94% I'm wondering if reducing it further could be dangerous for me.
Does anyone know the answer to this? I do hope it's ok and won't hurt my remaining grey matter!
