Understanding Why Do Horses Sleep Standing Up

Estimated reading time: 6 minutes

The horse is the only towed hoofed animal that sleeps while standing upright.

The relation between humans and horses can be traced back to 5000 years. A male horse is popularly known as a stallion, whereas a female horse is usually called a mare. When we look at them, standing in stables and shades, we pause to ponder about their standing style and how they can sleep while standing.

Usually, animals sit down at a leveled surface, make a comfortable posture, and then relax and sleep, but it is different with horses.

Horses are large animals weighing over 500kgs; their body and organs require a steady flow of blood circulation, which is only possible while standing.

Can you think of the possible poses they make while sleeping? Or how do they itch or roll over during sleep?

Why Do Horses Sleep Standing Up?

Horses usually stand upright when they are ready to ride or move. While standing in stables, they lock their joints, ligaments, and aligned tendons to maintain a decent posture.

Horses are adaptable to changes around them and can rest standing up and lying down. Like humans, horses also enjoy their sleeping routine and develop deep and regular sleeping habits in any environment where they feel more calm and relaxed.

Horses always fear tripping over and damaging their foot muscles; to avoid them, they prefer to sleep while standing.

Horses develop mutual trust and understanding when they are standing with their partners. If they are standing in an unprotected environment, they would coordinate with their partners and then sleep.

How do Horses Lay down and Rest?

Like many other animals, horses have developed muscles, limbs, and joints, which help them lay down compactly.

Horses prefer lying down completely when they are sleep-deprived and feel the need to rest.

Horses go Rapid Eye Movement sleep (REM) when they find a leveled surface and hard ground, they back themselves to completely lay down against the support. This specific action helps them in reducing their muscle activity and muscular strain.

During this position, the neurological activity is increased, whereas muscles remain relaxed. It is observed that a horse only spends one hour in REM sleep position.

While staying on the ground, horses exert their weight over the firm surface and place their chin towards the ground.

Why Is Stay Apparatus Found Inbuilt in Tall Animals?

Stay apparatus is something that is mainly associated with horses. It refers to the coordinated arrangement of tendons, ligaments, and muscles to accommodate the standing position in an animal without the need for any muscular effort.

Horses activate their stay apparatus while they want to relax and sleep while standing. When a horse feels dizzy or tired, its muscles and brain coordinate to activate the Stay apparatus, which locks the foot muscles rigidly and holds them in place.

The stay apparatus is formed by the combination of muscular contractions, ligaments, and tendons. Horses need to feel comfortable and attached to a firm ground before they prepare themselves to sleep.

Stay apparatus activates the light sleeping mode of horses, in which their limbs are stabilized, and they can sleep while standing. The hammock system of muscles locks their legs muscles, where the horse can relax without bending over.

What Helps Baby Horses to Sleep?

Just like every baby animal, baby horses (foals) spend half of the day sleeping. Biological research and studies show that foals are more concerned about sleeping and resting until the age of four months.

During the early days, foals regularly take a nap during the day until they can stand firmly and surefootedly. An adult horse sleeps for three hours on average, whereas foals can have a variable timetable and sleeping habits.

A comfortable space with a standing partner, a parent to look after it, and safeguard against any uncertain danger helps a baby horse sleep calmly.

What Conditions Can Affect the Pattern of Daily Sleep in Horses?

Change in the surrounding, ground conditions, and light intensity may affect the sleeping pattern of horses. Like every animal, horses need to feel confident and secure before they want their bodies to rest. Change in partners and shift in position in stables may affect the sleeping pattern of horses as they won’t feel much comfortable and at ease.

Extreme weather conditions can affect their sleeping space and make them uncomfortable while sleeping or holding their ground. Like every living organism, horses need a standard time to rest in any position and recharge their muscular strengths.

For How Many Hours a Horse Can Experience a Deep Sleep?

It might be just for an hour that a horse will experience a deep sleep and make its body fully stretched on the ground.

But again, if they stretch out, do horses rest standing up? Or they just tend to relax?

You cannot tell by just looking if a horse is actually sleeping or resting while standing. Adult horses sleep for two to five hours on average, in any posture or position depending upon their surrounding conditions.

The sleeping hours and patterns evolve with their age and living conditions. If a horse doesn’t get ample sleep, it will get more tired during field activities, and its pace would reduce with time.

It is essential to monitor the sleeping pattern of horses and their overall wellbeing to keep them healthy and fit over a long period.

Do Horses Snore?

Yes, it is common for horses to snore while sleeping. Most horses do not make a lot of noise when they snore, however, this does not have to be like this for all horse breeds. Some horses tend to be a little loud when they snore, so it varies from breed to breed.

How Do Horses Sleep in the Wild?

Horses in the wild can sleep the way they like; they can sleep while standing up, or they can lay down as per their comfort. The most preferred position to sleep in most horses is standing upright. They can easily sleep for many hours in this position, however, they sleep while laying down only for a few minutes.

You would rarely find horses in the wild laying down for several hours as this position does not come naturally to them.

Conclusion! Horses are among the most cherished animals, thanks to their stunning good looks, authoritative demeanor, and loyalty towards their owners. Like any other living being, horses have their preferences for various habits.

The sleeping mechanism in horses is different from many other animals, and this is what makes them unique. Most horses like to sleep while standing upright, as this is how their body is naturally designed to sleep.
