What REM means?
rapid eye movementWhen you get your ZZZs, you cycle between REM and non-REM sleep. REM stands for rapid eye movement. During REM sleep, your eyes move around rapidly in a range of directions, but don't send any visual information to your brain. That doesn't happen during non-REM sleep.

Which sleep stage is most restorative?
Stage 3 / N3Stage 3 / N3 The brain activity during this period has an identifiable pattern of what are known as delta waves. For this reason, stage 3 may also be called delta sleep or slow-wave sleep (SWS). Experts believe that this stage is critical to restorative sleep, allowing for bodily recovery and growth.

This means if you don't get enough REM sleep, you can throw off your circadian rhythm which can cause all types of sleep problems.
Which part of the brain produces melatonin?

What are the traces of REM sleep?
REM Sleep. Numbering the traces from top to bottom, 1 & 2 are electroencephalograms (EEG) of brain activity; 3 is an electrooculogram (EOG) of movement in the right eye; 4 an EOG of the left eye; 5 is an electrocardiogram (ECG) trace of heart activity. 6 & 7 are electromyograms (EMG) of activity in the laryngeal (6) and neck (7) muscles.
What is the purpose of an electroencephalogram?
An electroencephalogram (EEG) uses electrodes to read small electromagnetic waves from the human brain. Graphic_BKK1979 / iStock / Getty Images Plus. The major portions of the brain activated during REM sleep are the brainstem and the hypothalamus.

Why is REM considered a paradoxical state?
REM sleep is often described as a “paradoxical” sleep state due to its increased activity after non-REM sleep. The three prior stages of sleep, known as non-REM or N1, N2, and N3, occur initially during the sleep cycle to progressively slow bodily functions and brain activity. However, after the occurrence of N3 sleep (the deepest stage of sleep), ...
