How much time does a horse spend sleeping at night?
Horses typically spend anywhere from 4 to 15 hours a day in standing rest, and anywhere from minutes to several hours lying down. Only part of that time is actual sleep time, which is taken in brief naps that last a few minutes each. The daily total sleep time for an adult horse may range from a few minutes to a couple of hours. Foals and young horses, like other youngsters, sleep more, more deeply, and more often than adults.
