What time should I wake up?
The best wake time is the one you can hold consistently every day, including weekends, that gives you 7–9 hours of sleep. The exact clock time matters less than the regularity.
Consistency beats clock time
Research increasingly links regular sleep timing to better health: in a study of more than 60,000 UK Biobank participants, sleep regularity predicted mortality risk more strongly than sleep duration (Windred et al., 2024). A consistent 7 AM is better than alternating 5 AM weekdays and 10 AM weekends.
Match your chronotype
Late chronotypes have the largest gap between workday and free-day sleep, which creates social jet lag and sleep debt on workdays (Wittmann et al., 2006). Pick a time that aligns with your natural tendency where possible.
Total sleep matters
Hirshkowitz et al. (2015) recommend 7–9 hours for adults. Back-calculate your wake time from your latest reliable bedtime + 7–9 hours.
