How do they stand it?By Connie Orcutt • Published: November 1st, 2013

Horses are on their feet virtually all the time, which seems physically impossible. They can even sleep standing up!
Horses can lie down to sleep, but they usually choose not to. As prey animals, that would make them vulnerable to predators. Therefore, any horse that lies down to snooze really feels at ease.
Fortunately, horses have developed an ingenious anatomical feature that allows them to sleep standing up while exerting almost no effort. Called the stay apparatus, this complex array of tendons and ligaments supports an upright posture while keeping a horse’s muscles completely relaxed. These efficient equines also take advantage of the stay apparatus during waking hours to avoid getting tired.
So it would appear that our super steeds have found a way to stand the pressure.
