About SleepSmartCalc

The Science Behind Your Best Rest

Our Mission: Sleep Optimized

At **SleepSmartCalc**, we believe that quality sleep is the foundation of a productive and happy life. Our mission is simple: to transform confusing sleep science into easy-to-use, accessible tools. We strive to help every user discover their ideal **sleep cycles** and wake up feeling truly refreshed, not groggy.

"We calculate so you don't have to worry about missing the perfect wake-up window."

The 90-Minute Sleep Cycle Method

Our calculator is based on the scientifically recognized fact that the human body sleeps in **90-minute cycles**. Each cycle involves moving from light sleep into deep REM (Rapid Eye Movement) sleep. Waking up during a deep sleep phase leads to **sleep inertia** (that heavy, groggy feeling).

**SleepSmartCalc** works by calculating your **ideal wake up time** to coincide precisely with the end of one of these 90-minute periods (aiming for 4, 5, or 6 cycles), plus a mandatory 15-minute buffer for the time it takes the average person to fall asleep. This ensures you wake up during the lightest phase of sleep.
