“…breathing underlies intrinsic coordination of sleep oscillations in humans. Brain rhythms during sleep coordinate activity across different neural systems, as part of memory consolidation processes.”
Don’t have sleep apnea, obviously. I wonder about the effect of nasal breathing during sleep.

My best and deepest sleeps are always when my breathing rate is lowest per my Oura ring
Has someone ever reduce the respiratory rate? Mine doesnt move
I lowered mine via nasal breathing at night (mouth tape, at first) plus co2 tolerance drills (exhale breath holds 3x30 seconds with 1 breath between reps) and shallow breathing to hold spo2 <90% for 3-5min. CO2 tolerance training might (or not) have other benefits but don’t do these near water or anywhere where passing out would be dangerous.
