Sleep Cycles

Sleep Cycles are natural patterns of brain activity that repeat approximately every 90 minutes during the night. Each cycle moves through stages of light sleep, deep sleep, and REM (rapid eye movement) sleep, all of which play crucial roles in memory consolidation, physical recovery, and mental restoration.

Waking up in the middle of a deep sleep stage can leave you feeling groggy and unrefreshed. By timing your sleep so you wake at the end of a complete cycle, you can improve sleep quality, boost morning alertness, and start each day with more energy.
