Weekends, stress and sleep debt: the three biggest triggers

Sleep debt: after short nights the brain compensates with REM rebound, packing more REM into the next sleep. More REM, more overlap opportunities.
Key idea
Stress and anxiety: cortisol fragments sleep and increases brief awakenings. It is the fragmentation, not the worry itself, that creates the opening.
Sleeping on your back: episodes are reported far more often when supine, likely because of airway sensations and how the body senses pressure while immobile.
Alcohol, late caffeine, irregular hours and screens in bed all work through the same route: fragmented, shifted REM.
Protect a regular wake time.
Try side sleeping for two weeks.
