Why Sleep Cycles Matter

Understanding Sleep Cycles

Sleep cycles diagram

Sleep consists of multiple 90-minute cycles, each containing REM and non-REM stages. Waking up at the end of a cycle (after 6, 7.5, or 9 hours) helps you feel refreshed.

Frequently Asked Questions

How does the sleep calculator work? +

The calculator uses the science of sleep cycles (each ~90 minutes) to determine optimal wake-up or bedtime. It adds/subtracts multiples of 90 minutes to find times when you'll be in lighter sleep phases.

Why 90-minute cycles? +

Research shows sleep progresses through stages (light, deep, REM) in roughly 90-minute cycles. Waking between cycles (after 6, 7.5, or 9 hours) reduces grogginess compared to waking mid-cycle.

How accurate is this calculator? +

It provides estimates based on average sleep cycles. Individual variations exist, so experiment to find what works best for you. The "best" time is usually after 5 full cycles (7.5 hours).

What if I don't feel rested? +

You may need more cycles (try 9 hours) or should evaluate sleep quality factors like stress, diet, or sleep disorders. Consistency is key—stick with a schedule for at least a week.
