What to do
Go to bed before 11 PM. Log your bedtime. The habit is the timing, not just the duration.
Why it works
Early bedtime is associated with better sleep quality, deeper REM sleep, improved mood, better cognitive function, and reduced risk of metabolic disorders. Consistent early bedtimes strengthen circadian rhythm.
Research backing
Sleep researcher Matthew Walker's synthesis of circadian science shows that consistent sleep timing strengthens the body's internal clock, improving sleep architecture and next-day cognitive performance more reliably than sleep duration alone.
