- What is a Sleep Cycle?
To put it simply, a sleep cycle is what your brain does while you’re getting your zzz’s. As you sleep, your brain goes through various patterns of activity. These patterns are based on distinct eye movements and muscle activity. In fact, sleep scientists have tracked these movements and found two main sleep cycle categories: rapid-eye-movement (REM) sleep and non-rapid-eye-movement (NREM) sleep.
Your natural sleep cycle lasts about 90 minutes. During this time your brain moves through five different stages.
1. Your brain begins to slow down. You are lightly sleeping, drifting in and out.
2. Your eye movement stops and the brain begins to relax. This is a period of light sleep before you enter a deep sleep.
3. Your brain waves begin to slow even more. They are preparing for the deepest stages of sleep.
4. This is the deepest stage of sleep. It's important for you to reach this stage for a good night's sleep and it’s also important that you are not awoken during this stage. That will make for a very grouchy morning.
5. This is the rapid-eye-movement (REM) stage of sleep. Most of your dreaming occurs during this time. Again, make sure you are not awoken during this stage because you will likely feel disoriented.
- How Many Sleep Cycles Should You Get Each Night?
A typical night's sleep consists of about 5-6 full sleep cycles. But each of these sleep cycles is different from one another. During the first 2-3 sleep cycles, you spend most of the time in a deep NREM sleep. In the final 2-3 sleep cycles, you will spend more time in REM sleep and stage one light sleep. By using a Sleep Cycle App, you can time your alarm to go off during your lightest sleeping period.
- How long is a REM Cycle?
The REM stage of sleep is unique because it's when you have your most vivid dreams. 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. Your brain is also converting experiences into memories. Furthermore, it enhances your ability for creative problem-solving. These are all important reasons to make sure your alarm doesn't wake you up during this crucial stage of sleep.
