The two types of sleep

There are two types of sleep.

Sleep involves cycles of two different types of sleep: rapid eye movement and non-rapid eye movement sleep. We can measure these using Electroencephalography (EEG).

In this video we look at the different physiological changes that occur during both rapid eye movement and non-rapid eye movement sleep. We also highlight the importance of sleep for young children.
