Why do we sleep, and what is actually happening inside the brain while we’re unconscious?

This video explores the fascinating science of sleep — from the discovery of brain waves, REM sleep, and the different stages of sleep to circadian rhythms and the biological pressure that makes us tired. We also look at how sleep supports memory, emotional processing, brain maintenance, and the essential processes that help restore the brain and body each night.    Pasted markdown
A slow journey through one of biology’s biggest mysteries — why we need sleep and what happens when we don’t get enough.
