Understanding sleep cycles

OK, so there are two teams in our sleep league: REM (Rapid Eye Movement) and NREM (Non-REM), and they play games that last all night. Then you have the four stages, which are the halves of each match.

Each team plays differently. NREMs clean up your brain, while REMs are the storytellers of your wildest dreams.

How long is a sleep cycle?

A complete cycle? Think of it a bit like the complete set of a good quality series, generally it takes 90 to 110 minutes. But be careful, as the number of seasons can vary from one series to another, the length of your cycle depends on factors like your age and your habits.
