Sleep Cycle Calculator

The Sleep Cycle Calculator is a free tool designed to help you get better sleep every night. To do this we track the body's natural 90-minute sleep cycle, and calculate the best times to go to sleep and wake up. This prevents you from waking up in the middle of deep sleep, which can make you feel tired and dazed.

Using this calculator can be a huge benefit to your day, as it is best to wake up during light sleep to feel refreshed. So, if you need to wake up early or want to take a nap, this tool can help you align your sleep with your body’s natural rhythms for better sleep.

What is a sleep cycle calculator?

A sleep cycle calculator is an online tool that enables you to determine the best times to wake up or sleep based on your sleep's natural cycles. Human sleep consists of different stages, including light sleep, deep sleep, and REM sleep, and a single sleep cycle would typically last around 90 minutes. By aligning your sleeping habit with these cycles, a sleep cycle calculator helps you wake up more alert and refreshed, by attempting to have you wake at the end of a cycle rather than during the middle of deep sleep.

How does a sleep cycle calculator improve my sleep?

The use of a sleep cycle calculator can improve your sleeping by optimizing the timing of when you sleep or wake up. By sleeping in complete cycles, you reduce the chances of waking up in deep sleep, which makes you feel disoriented and groggy. This synchronization can enhance the quality of sleep, boost morning energy, and make it easier to maintain a consistent sleeping schedule, which is beneficial to both mental and physical health.
