Your circadian rhythm is the internal 24-hour clock that governs when you feel sleepy and when you feel alert. When it falls out of sync — due to travel, screen time, or irregular schedules — sleep quality suffers and daytime focus drops.
Light is the most powerful lever you have. Getting 10–20 minutes of natural light within an hour of waking anchors your clock for the day, while dimming screens and overhead lighting in the evening signals your body to wind down.
Consistency matters more than duration. Going to bed and waking at the same time every day — even on weekends — trains your system to release melatonin and cortisol at the right moments, making both sleep and wakefulness feel effortless.
