📋 Sleep Hygiene & Circadian Summary

Medical recommendations for restful sleep

The 10-3-2-1-0 Golden Sleep Rule:
10 Hours Before Bed: No more caffeine (tea/coffee)
3 Hours Before Bed: No heavy food or alcohol
2 Hours Before Bed: No stressful work or tasks
1 Hour Before Bed: Turn off all mobile & TV screens

💡 Why 90-minute sleep cycles matter:

Waking up in the middle of deep sleep (slow-wave sleep) causes “sleep inertia,” leaving you feeling exhausted and dizzy even after 8 hours. Waking up at the end of a full cycle ensures effortless awakening.
