Frequently Asked Questions
Adults need 7-9 hours of sleep per night. Teenagers need 8-10 hours, school-age children need 9-12 hours, and toddlers need 11-14 hours including naps.
A sleep cycle lasts about 90 minutes and consists of 4 stages: light sleep (N1), deeper sleep (N2), deep sleep (N3/slow-wave), and REM sleep. Most adults go through 4-6 cycles per night.
To wake up refreshed at 6 AM, ideal bedtimes are 9:00 PM (6 cycles), 10:30 PM (5 cycles), or 12:00 AM (4 cycles). Allow 15 minutes to fall asleep.
Waking in the middle of a deep sleep cycle can cause grogginess. Try adjusting your wake time by 15-30 minutes. Other factors include poor sleep quality, sleep apnea, stress, or inconsistent sleep schedules.
Short naps (20-30 minutes) can boost alertness and performance. However, naps longer than 30 minutes or taken after 3 PM may interfere with nighttime sleep quality.
