Your circadian rhythm is your internal 24-hour clock governing alertness, sleepiness, and biological processes. When aligned with your lifestyle, sleep comes naturally. When misaligned, no amount of willpower can fix it.
Artificial light after sunset, irregular sleep schedules, jet lag, shift work, chronic stress — all throw your clock out of alignment.
Morning Light: 10 to 30 minutes of bright natural light within the first hour of waking. Evening Light Reduction: Dim lights two to three hours before bed. Consistent Timing: Fixed wake-up and bedtime for at least two weeks. Timed Melatonin: A small dose 30 to 60 minutes before target bedtime.
Yu Sleep provides both the melatonin circadian signal and the nervous system calming (GABA, L-Theanine) needed to fall asleep when your body thinks it should be awake. Learn how the formula supports circadian alignment or order today.
