Lock Wake Time First
A stable wake time anchors circadian rhythm better than chasing perfect bedtime. It improves nighttime sleep pressure naturally.
Morning sunlight within one hour of waking is a high-return intervention.
Cut the Biggest Sleep Disruptors
Late caffeine, alcohol near bedtime, and hot sleep environments are common causes of fragmented sleep. Remove these before buying gadgets.
Keep your room dark, cool, and quiet.
Track Recovery Signals
Use daytime energy, mood stability, and training recovery as primary outputs. Wearables are helpful, but your daytime function matters most.
If snoring and daytime sleepiness persist, screen for sleep apnea with a clinician.
