The Concept
Sleep latency refers to how long it takes to fall asleep — not how long or how well you sleep.
The Explanation
• Sleep onset is tied to nervous system arousal
• Hyperarousal delays sleep
• The endocannabinoid system influences wake–sleep transitions
The Clarification
This explains why something can help you fall asleep faster without improving sleep quality.
Different sleep processes are controlled by different systems.
Understanding which process is affected changes expectations — and decisions.
