i'm a newbie that's interested in exploring breathwork for the main purpose of optimizing my sleep. I need help from the community of experienced people in the art of breathing. I want to practice a suitable type of breathwork that will: 1. Get me to fall asleep faster, possibly by reducing stress/anxiety; 2. Reduce the amount of time I wake up during the night; 3. Get me more oxygen while I was asleep, thereby reducing snoring / sleep apnea; Other bonuses such as better mood, cognitive functions, athletic performances, trauma healing are welcomed, but not the main priority. I may want to try other types of breathwork(s) for these purposes, but optimizing my sleep is really paramount here (at least for me).
