Sleep
The Sleep pillar documents what controlled research has actually found about cannabinoids and sleep — including polysomnographic human data for CBD that makes this one of the better-evidenced areas in the archive. The relationship between stress and sleep disruption runs through both this pillar and the Stress & Anxiety pillar.

Sleep Architecture and CBD: What Polysomnographic Research Shows
Sleep isn't one continuous state — it moves through distinct stages, and researchers have used lab measurements to study how CBD affects that cycle.
Tier 1 · Polysomnographic data
REM Sleep Behavior Disorder and Cannabinoids
A serious neurological sleep condition where the body acts out dreams — what it is, why researchers are studying cannabinoids in relation to it, and what the early evidence shows.

Anxiety, Stress, and Sleep: Understanding the Research Overlap
Anxiety disrupts sleep and poor sleep amplifies anxiety — why these two problems are biologically entangled, and what that means for reading cannabinoid research in both areas.
The Circadian System and the ECS: Rhythm, Sleep, and Endocannabinoid Tone
CB1 receptors in the suprachiasmatic nucleus and diurnal ECS tone fluctuation position the endocannabinoid system inside circadian regulation — what research has established.
