Zzzzzzz..
Zzzzzzz...
We humans may need our eight hours of sleep a night to keep our brains functioning, but that's not the only duration, or reason, why animals sleep. Bats sleep for 20 hours out of the day while giraffes snooze for less than two hours a day. And while humans completely conk out, oblivious to the world, other animals have very different modes of sleeping. For example...
Dolphins and whales have the ability to sleep with only one-half of their brain at a time. This prevents them from drowning in their sleep.
Sea Otters will sometimes hold hands when they sleep so they don't drift away from each other.
Giraffes can go weeks without sleep. Being large and rather slow animals, they're constantly vulnerable to attacks from predators, and therefore cannot sleep for long periods.
Migrating birds can sleep whilst flying. Some species of birds fly for 6 months straight migrating, drinking and sleeping whilst airborne. Scientists have found that migrating birds can fly for 200 days straight, eating and sleeping while soaring through the sky.
Cows like to sleep close to their families, and sleepng arrangements are determined by individuals' rank in the social hierarchy.
The variety of ways animals sleep is staggering, and researchers are only beginning to make a dent in understanding the inner workings and purpose of sleep among different species. A clear conscience is a great sleep aid for us humans. Think how soundly you can sleep at night if you've not been eating other animals!
Do the compassionate thing, have your next meal at a http://KindMeal.my partner, and sleep like a baby tonight.
