When the alarm clock wakes us up suddenly from deep sleep or interrupts the REM phase, our body doesn't appreciate it. Usually each cycle takes about 90 minutes. Interestingly enough, while your brain waves frequency is much higher than it was when you were in the deep sleep phase, it's even harder to wake you up.Īfter some time in the dreaming REM phase you fall back into deeper sleep and the cycle repeats. Your body is more or less paralysed, but your eyes move rapidly. REM stands for Rapid Eye Movement and describes the dreaming phase of your sleep. This is when the magic happens and you switch from NREM to REM sleep. Your brain doesn't stay in the deep sleep for long - within 90 minutes it speeds up back to theta and then to alpha waves. This means it's more difficult to wake up someone who's in the Slow Wave Sleep.

in stage 3 of NREM, your brain oscillates much slower and is less perceptible to stimuli like light or sound. These are three NREM (Non-REM) stages of sleep. Brain waves frequency goes down from what we call alpha (8–13 Hz) to theta (4–8 Hz) and finally delta (1–4 Hz) frequency bands.
