Sleep Cycle Optimizer
Find the optimal times to sleep and wake based on 90-minute sleep cycles and your circadian rhythm. Get personalized recommendations with circadian scoring.
Applications
Perfect for anyone who wants to optimize their sleep schedule. Whether you're a night owl trying to fix your schedule, a parent optimizing your child's sleep, or a fitness enthusiast timing sleep for recovery.
Circadian Rhythm Scoring
Sleep cycles are 90 minutes each. This calculator adds a buffer for falling asleep and scores recommendations based on your circadian rhythm. Sleep before 10pm is 'Optimal', between 10pm-midnight is 'Good', midnight-2am is 'Late', and after 2am is 'Very Late'.
Fun Fact: Your circadian rhythm is primarily set by light exposure. Blue light from screens can trick your brain into thinking it's still daytime, making it harder to fall asleep at the optimal time.
