Sleep Cycle Calculator: What Time Should I Go To Bed?
You’ve probably heard that you need to get 8 hours of sleep per night to feel fit and rested. While it is important to get plenty of sleep, it doesn’t necessarily mean you will be more rested. The ideal time to go to sleep at night depends on when you have to wake up the next morning. This sleep cycle calculator can help you get to know your rhythm and wake up more refreshed.
Now it’s time to sleep
The sleep cycle calculator tells you when you should go to bed to wake up refreshed:
Keep in mind that this bedtime is just an estimate and that it takes an average of 14 minutes to fall asleep, so you may have to go to bed a little earlier than the time calculated by the calculator.
Maybe you’ve noticed that there is 90 minutes between each suggested bedtime. Why is that, you ask?
Each sleep cycle lasts 90 minutes
A good night’s sleep consists of five to six sleep cycles. During each cycle, our body goes through the following five sleep stages:
1. Light sleep stage
2. Light sleep stage
3. & 4. Deep sleep stage
5. Dream or REM sleep stage (REM stands for rapid eye movement. During REM sleep, your eyes move rapidly, and you experience vivid dreams).
If you wake up during one of these stages, you will feel sluggish and tired.
