Your body doesn’t like being disrupted during the deep sleep phase, so if you don’t time your alarm to match your internal clock, you may wake up feeling groggy and tired. It’s at this stage that you’re most likely to dream. Once you reach the REM stage, your body will be in a deep sleep for the rest of the 90-minute sleep cycle. During NREM sleep, you can easily be awoken by a slight disturbance, but as you cycle through these phases, your brain waves begin to slow down, in preparation for deep sleep. This is the time your body goes into NREM, also known as the light stages of sleep. The first 2 to 3 stages of the sleep cycle occur shortly after you drift off. Each sleep cycle lasts approximately 90 minutes, and consists of two main categories: Rapid Eye Movement (REM) and Non Rapid Eye Movement (NREM).

While you sleep, your brain goes through a series of 5 to 6 sleep cycles that enable your body to rest and recover from the day. Whether you’re an early riser or like to sleep in, maintaining a regular sleep schedule can help you to keep your rhythm in check. But for night owls and shift workers, this circadian rhythm can change. Most of us start getting sleepy when the sun goes down and alert when the light leaks into our bedrooms in the morning.
This internal rhythm is triggered by hormones in the brain, but it also relates to the light we receive throughout the day.
Just like the hours of the day, humans run on an internal clock that tells us when we should go to sleep each night and wake up each morning. But before we get into it, let’s review the basics of sleep biology. Which is exactly why we’ve created the ultimate guide to building a better sleep schedule to fit your daily routine. Mornings can be tough, especially when we’re not getting the sleep we need.
