Do Horses Sleep Standing or lying down? Why?

Question

In God's Creations, there are some mysteries. One such mystery animal is this horse.

Does it sleep in a Standing position as it is commonly believied to do?

A scientific approach to this issue with some humor is welcome!

Answer 1

Horses have a unique system of interlocking ligaments and bones in their legs, which serves as a sling to suspend their body weight without strain while their muscles are completely relaxed. Thus, horses don't have to extent any energy consciously to remain standing - their legs are locked in the proper position during sleep.

Most horses do most of their sleeping while standing, but patterns differ. Veterinarians we spoke to said it was not unusual for horses to stand continuously for as long as a month, or more. Because horses are heavy but have relatively fragile bones, lying in one position for a long time can cause muscle cramps.

While one can only speculate about why the horse's body evolved in this fashion, most experts believe that wild horses slept while standing for defensive purposes. Wayne O. Kester, D.V.M., executive director of the American Association of Equine Practitioners, told us that in the wild, the horse's chief means of protection and escape from predators was its speed. "They were much less vulnerable while standing and much less apt to be caught by surprise than when lying down".

the big question: How does a horse sleep standing up? The answer lies in a system of tendons and ligaments that work together with the knee cap. Animal experts call this the "stay apparatus." It's a pretty clever design, really. At any time, a horse needs only to relax the muscles on his front legs, and the stay apparatus will kick in. For the back legs, a horse must rotate its hips to activate the built-in locking mechanism.

Over a period of 24 hours, a horse will be drowsy for about two hours, sleep lightly for two hours, and sleep deeply for less than an hour. But these are totals. Each day, the horse has several drowsy and sleep periods of only a few minutes each. Of course, the horse can sleep lying down if it so chooses, but God has designed this magnificent animal to get forty winks on four legs.

Answer 5

A horse sleeps standing up because of its natural instincts from past generations that lived in the wild. Horses slept standing up so they could flee from any predator that tried tocome upon the herd.

Answer 6

They sleep lying down when they feel completely safe. However they are able to doze for long periods standing up. That is not a restful sleep.

Answer 7

they need to sleep standing up, otherwise their insides get all tangled up and they can die. cows can sleep lying down 'cause their stomachs are divided, but it can be really dangerous for horses. my grandpa actually had a horse that died because of that (among other things).
