6 animals that can sleep standing up without falling – Horses

Next time you pass by a Gaushala or a village farm, keep a close eye on the cows. They spend much of their day “napping” while standing, while lying down to relax or falling into a deep sleep. They are quite stable on all fours and can experience light sleep states without losing their balance. But just like us, they eventually need to lie down to dream, but for a quick recharge, a standing position works just fine.
