How We Calculate Your Sleep

Our sleep cycle is a pattern that repeats itself while we sleep. It has different stages, mainly rapid eye movement (REM) sleep and non-rapid eye movement (NREM) sleep.

During these stages, our body rests, repairs, and grows. REM sleep is when we have vivid dreams and our brain is very active, helping us remember things and deal with emotions. Overall, sleeping is immensely important for your health.

Knowing your sleep cycle is essential to figure out the best time to go to bed. That’s why we developed this sleep calculator. Most people feel best when they wake up after 5 or 6 complete sleep cycles, and the average sleep cycle is 90 minutes. You should also allow for 15 minutes to fall asleep.

By understanding your sleep cycle, you can choose a bedtime that allows you to wake up feeling refreshed and ready for the day. If you wake up feeling groggy or tired, you might need to adjust your bedtime to align better with your sleep cycle.
