WHAT IS REM SLEEP?
• REM (Rapid Eye Movement) sleep is a stage in the sleep cycle when you dream and your brain is most active. Deep sleep and light sleep alternate in cycles, and REM is known for vivid dreaming and brain activity.

• Waking up at the end of a REM sleep cycle (usually every 90 minutes) helps you feel more refreshed and less tired in the morning.
