Find out when you should go to bed, and when you should wake up in order to get the best night’s sleep with the Sleep cycle calculator.
During your first cycle of sleep, it starts about 90 minutes after you fall asleep and last only 10 minutes. Each cycle after that, your REM sleep gets longer and longer. In the final cycle is may last up to an hour. During your REM sleep cycle, your eyes are darting around and “seeing” different things.
The calculator is designed to help you wake up during Stage 1, the lightest rest. There are three ways to use this calculator to generate your custom bedtime duration. The first option is to input the time you need to wake up. The tool will then provide you with recommended bedtimes. The second option is to input that you’d like to go to bed right now, and the calculator will show you when to wake up. Thirdly, you can choose to input when you’d like to go to bed later that night, and the tool will give you recommended wake-up times.
Each stage accumulates to REM (rapid eye movement) sleep, and then restarts, completing one cycle. The first stage through REM takes about 90 minutes to complete, and adults typically need to complete at least four or five sleep cycles per night, or 6 to 9 total hours of sleep.
In a typical night, a person goes through four to six sleep cycles. Not all sleep cycles are the same length, but on average they last about 90 minutes each.
“The window of 10 pm to 4 am mostly correlates with a major part of the circadian rhythm of sleep for most individuals. This window can be anywhere between ten in the night to eight or nine the next morning. Hence following that can help your sleep as well as allow the circadian rhythm to function properly.
These groups currently recommend seven to nine hours of nightly sleep for healthy adults. The National Heart, Lung and Blood Institute recommends seven to eight hours, including the elderly. Most current guidelines say school-age children should get at least 10 hours of sleep a night, and teenagers, nine to 10.
People who go to bed late and wake up late can often experience health problems because their body clock does not align with the regular rhythms of modern society. However, a new study suggests that a few easy routine adjustments could go a long way for night owls.
Getting a healthy amount of sleep is a key part of a good sleep pattern. The National Sleep Foundation recommends that most adults get between 7 and 9 hours of sleep each night and that older adults over 65 years of age get between 7 and 8 hours.
