Like humans and other animals, horses need sleep, but their sleeping habits are quite different from ours. As prey animals naturally live on the plains, horses have evolved to be constantly alert for predators. This raises the question: How Do Horses Sleep? Let’s explore how horses sleep.

Do Horses Sleep Standing Up?
Yes, horses do sleep standing up, but they don’t sleep deeply this way. It’s a bit more complex than it seems.
Horses nap or snooze while standing but do not achieve deep REM sleep in this position. Lying down can be dangerous for a horse because it takes time for them to get up, making them vulnerable in the wild.
Horses, like other large prey animals, have a ‘stay apparatus’—a system of tendons and ligaments that lock their major joints. This allows them to remain standing without muscular effort and prevents them from falling over while sleeping. A horse often rests a hind leg by taking the weight off it and distributing its weight over the other three legs during sleep.
During this dozing sleep, horses can easily wake up and be ready to flee if a threat arises. Additionally, lying down for too long can restrict blood flow and put excessive pressure on their internal organs, making prolonged lying down impractical.

Deep Sleep in Horses
Dozing while standing does not allow horses to enter deep REM sleep, which is necessary for their well-being. REM sleep requires full muscle relaxation, which can only be achieved while lying down, thus putting them at risk. Consequently, horses only lie down for short periods of about 20 minutes to achieve REM sleep.
In a stable, horses maintain this pattern, sleeping in short bursts and grazing in between. When outdoors in a herd, horses may take turns lying down to sleep deeply while others stand guard. This cooperative behavior helps ensure the safety of the group.
How Long Do Horses Sleep?
Unlike humans, who need about eight hours of sleep, horses only need around three hours of sleep in 24 hours. These three hours are spread out in short bursts throughout the day and night.

How to Tell When a Horse Is Sleeping
When a horse is in deep sleep, it will be lying down, and you might see its legs twitch if it’s dreaming.
When a horse is dozing, it can be harder to tell, but there are signs. A dozing horse will typically lock one of its hind legs while resting the other, which will be slightly raised with the hoof tip touching the ground, giving the appearance of leaning on one hip. The horse’s eyes will be closed, its head will droop, its ears will be relaxed, and its lower lip may droop as well.
In summary, horses have unique sleeping habits adapted to their needs as prey animals. They doze while standing, using their stay apparatus to stay upright and alert, and only lie down for brief periods to achieve the necessary deep REM sleep.
