"Let's answer the question: How long can someone sleep for? A normal sleep-wake cycle follows your body's natural circadian rhythm. To find out what would happen if there were no time cues, like sunlight and environmental noise, scientists have performed studies on test subjects kept in isolation, letting them set their own sleep-wake cycle. These studies found a wide variation in sleep duration and that it largely depended on the subject's body temperature, which also rises and falls following the circadian rhythm. If they went to sleep near the peak high temperature, which typically happens during the daytime, they slept for longer periods. In some instances, their sleep-wake cycles lengthened to up to 50 hours, with them sleeping for up to 20 hours at a time. On the less extreme side, there is a sleep disorder called hypersomnia, where people can sleep for up to 12 hours a night."
