What is a Sleep Cycle?

A sleep cycle is a natural pattern of sleep that your body goes through during rest. Each cycle lasts approximately 90 minutes and includes different stages of sleep, such as light sleep, deep sleep, and REM sleep.

Waking up in the middle of a cycle can make you feel tired, while waking up at the end of a cycle helps you feel more refreshed. This sleep cycle calculator helps you align your sleep schedule accordingly.

Sleep Calculation Formula Explained

The sleep calculator online works using a simple concept:

• 1 Sleep Cycle ≈ 90 minutes
• Recommended Sleep = 4 to 6 cycles
• Total Sleep Time = 6 to 9 hours

Additionally, about 10–15 minutes is added as the average time it takes to fall asleep.
