Frequently Asked Questions - Sleep Calculator
Sleep cycles are approximately 90-minute periods that include light sleep, deep sleep, and REM sleep stages. Waking up at the end of a complete cycle helps you feel more refreshed and alert, rather than groggy. Our calculator times your sleep to align with these natural cycles for optimal rest quality.
Sleep needs vary by age: Teenagers (14-17) need 8-10 hours, Adults (18-64) need 7-9 hours, and Seniors (65+) need 7-8 hours. Children (6-13) require 9-11 hours. Our calculator adjusts recommendations based on your age group and provides personalized timing suggestions.
Chronotype refers to your natural preference for being active at certain times of day. Early birds naturally wake up early and feel most alert in the morning, while night owls prefer later bedtimes and peak alertness in the evening. Our calculator adjusts sleep timing recommendations to match your chronotype for better sleep quality.
Improve sleep quality by: maintaining a consistent sleep schedule, avoiding screens 1-2 hours before bed, keeping your bedroom cool (60-67°F), using blackout curtains, avoiding caffeine 6 hours before sleep, exercising regularly but not close to bedtime, and creating a relaxing bedtime routine.
Waking up tired despite adequate sleep duration often means you're waking up in the middle of a sleep cycle rather than at the end. Our calculator helps time your wake-up to align with natural sleep cycle endings. Other factors include poor sleep quality, sleep disorders, stress, or an inconsistent sleep schedule.
