Horses sleep in three different positions: standing, semi-recumbent, and fully recumbent.
Each of these positions allow the horse to reach different levels of sleep.
1. Standing, which is the safest position for a prey animal, offers the lightest level of sleep.
This allows the horse to wake and run away quickly if in danger.
2. Semi-recumbent, as shown in the picture, is where the horse lays down, but with their legs underneath them.
This allows for a deeper sleep than standing, but their legs are still underneath them for a quick stand up and run away.
3. Fully recumbent is where a horse is laid flat out on their sides. This is the only position in which a horse can get to REM sleep - deep, restful sleep.
However due to the horse's body size, they can only lay fully out for 45 minutes a time or risk crushing internal organs.
In total, horses need anywhere from 30 min to 3 hours of REM sleep a day.
What happens if a horse doesn't get enough sleep? In the next post we'll go over common symptoms of a sleep-deprived horse.
