Horses are polyphasic sleepers, which means they have multiple, discrete sleep episodes in a 24-hour period. Time budgets show that horses spend one to three hours (adding up all sleep episodes) in a 24 hour period lying down, in both sternal (upright) and lateral (flat on side) recumbency. Differences are seen according to feeding and turnout management (horses tend to lie down less in constant turnout).
Registered: 3-2011. There is a very old horse at the barn where my daughter boards. He cannot get up on his own. Lately he has been falling/going down and staying down for hours. He has been down more than once for as long as 16 hours before he was able to get up with help.
