Quality sleep is fundamental to physical and mental health, yet many people struggle with sleep disorders. During sleep, the brain processes memories, removes toxins, and regulates hormones. Chronic sleep deprivation increases risks for obesity, heart disease, and depression.

The circadian rhythm, our internal biological clock, regulates sleep-wake cycles. Blue light from screens disrupts this rhythm, making it harder to fall asleep. Experts recommend maintaining consistent sleep schedules and creating dark, cool sleeping environments.

Emerging research on sleep stages reveals why both REM and deep sleep are essential. While sleep needs vary by age, most adults require 7-9 hours nightly for optimal functioning.
