Definition of Sleep.

"Zzz...what's that? If you thought of sleep, you're absolutely right! Sleep constitutes a natural and recurring state of rest essential for both the mind and body.

REM vs. Non-REM Sleep.

REM sleep is characterized by vivid dreams, faster respirations, and increased brain activity, while non-REM sleep is the deep and restful phase of the sleep cycle associated with slowed breathing, muscle activity, heartbeat, and brain waves. REM and non-REM are like the bread and butter of sleep, complementing one another.

How Sleep Affects the Brain and Body.

Have you ever woken up with a new solution to a problem? That's because when you are sleeping, your brain  performs many functions from memory consolidation to muscle recovery.
