Different animals have different sleeping habits. The sleepiest animals can sleep up to 22 and 24 hours straight, while others need as little as 2 hours of sleep, for instance, the giraffe.
These sleeping patterns are typically influenced by factors such as activity, the species’ requirements, and food.
While sleep plays a vital role in human development – with too much and too little having an impact, this simply isn’t the case for some animals.
With this in mind, we have created a guide looking at the different animals that sleep the most, as well as the ones that sleep the least.
Grab your pillows and blankets, as we jump straight into exploring the sleepiest animals.
How Much Sleep Do Animals Require?
Similar to humans, animals require sleep, however, the required amount of sleep necessary depends on the species.
Some animals are nocturnal which means they sleep through the day and are active at night, while others sleep during the night and vice-versa.
Sleep is necessary for all animals, helping organisms relax, remain balanced, and recover energy – this is particularly important for a healthy metabolism.
Therefore, if you are wondering whether they are any animals that don’t sleep (see also: Animals That Don’t Sleep)at all, there simply aren’t any – all animals need to sleep.
The only difference between animal sleeping habits is the amount of sleep they require to remain happy and healthy.
15 Animals That Sleep A Lot
Here, we are going to explore the animals that sleep the most. While all animals are required to sleep, their longevity differs dramatically, as well as how they sleep.
For instance, some animals tend to hibernate (see also: Animals That Hibernate)during the winter months to survive the colder and longer periods when resources are scarce and to help conserve energy.
However, today we aren’t focusing on hibernating animals, instead, we’re focusing on animals that sleep the most during the day.
Koalas, otherwise known as Phascolarctos cinereus, are categorized as herbivores – belonging to the marsupial family. You’ll most likely see these adorable creatures high up in the trees since they find it difficult to move around on the ground.
In addition to this, koalas are known as the sleepiest animal species, known to sleep around 22 hours a day! With their remaining two hours of the day, they use this time to feed and perform basic requirements.
You may be wondering why koalas sleep so much, well; the answer lies in their diet. Since their diet consists mainly of eucalyptus leaves, which are low-nutrient plants, most of their energy is focused on digesting this food properly.
Fun Fact: Koalas love to eat. Per day, they can feed on up to one kilogram of eucalyptus!
Sloths belong to the suborder, Folivora, and are able to sleep up to 20 hours a day!
Among the different animals, sloths have one of the most interesting sleeping habits, too. Whereby they can be found hanging onto a tree sleeping or curled into a ball.
Moreover, domesticated sloths are known to sleep even longer – up to 23 hours a day. This is primarily due to the fact that they aren’t responsible for finding their own food.
