DozeClock publishes general information from population studies. It is not medical advice and does not replace a clinician who knows you.

The sleep-duration ranges, cycle lengths, nap timings and caffeine figures on this site are averages and consensus recommendations for broad age groups. They do not account for health conditions, medications, pregnancy, shift work, sleep disorders or individual metabolism. If you have persistent trouble falling or staying asleep, feel unrefreshed despite enough time in bed, or are concerned about caffeine or sleep and a medical condition, talk to a doctor or a sleep specialist.

This site does not discuss medication, supplements or treatments, and nothing here should be read as a recommendation to start, stop or change any of them.
