Learn sleep hygiene

About this idea

Adopt evidence-based habits and environmental conditions promoting consistent, quality sleep—foundation of physical health, mental wellness, and cognitive function.

Core principles: Consistency (same sleep/wake times daily—even weekends, regulates circadian rhythm), environment (dark, quiet, cool 60-67°F, comfortable mattress), pre-sleep routine (wind-down activities, dim lights), avoid: caffeine after 2pm, alcohol (disrupts sleep architecture), screens 1-2 hours before bed (blue light suppresses melatonin), large meals before bed, daytime: exercise (but not close to bedtime), natural light exposure (sets circadian clock), limit naps (if needed: 20-30 minutes before 3pm).

Sleep affects everything: immune function, weight regulation, emotional stability, memory consolidation, disease risk. Chronic sleep deprivation epidemic—intentional prioritization needed. Non-pharmaceutical intervention. Requires consistency and patience. Investment in overall health.
