The two phases of sleep are broken down into four cycles. The first three cycles take place in non-REM, and the last stage happens during REM sleep. During these stages, a person’s body goes through multiple physiological changes that are vital for physical and cognitive health4. Non-REM ...

On average a person will have around 4-5 slow-wave cycles. It’s extremely hard to wake someone up once they have entered the slow-wave cycle of their sleep but the body is movable. Delta sleep lasts only for a few minutes before the next stage takes over. ...
Below, we’ll go over everything you need to know about sleep cycle stages, what sleep cycles are, and how to get a good night’s sleep—every day of the week. Why Do We Need Sleep? Before we dive into the various stages of sleep and sleep cycles, it’s essential to know why we...
Instead of focusing on the exact number of minutes you spend in each stage, learn about the fluctuation between sleep stages and what the typical cycles look like for you. While you sleep, your body cycles through the different sleep stages, usually spending the most time in light sleep (...
