Which Animal Sleeps The Most

Which Animal Sleeps The Most? Find Out Below

No matter the species, animals are made to sleep. Sleep is essential for their well-being, as it helps them stay healthy and energetic. It also allows them to rest and digest food. But how do they spend their day sleeping? Which animal sleeps the most?

The animal that sleeps the most is the koala. Koalas are sleeping for about 18 to 20 hours a day. They sleep so much because they have a very low metabolic rate, which means that they don’t need to eat as often or as much as other animals.

The animal that sleeps the least is the camel. Camels only sleep for 2-3 hours a day because they have such a high metabolic rate. They need to eat more frequently than other animals and therefore can’t afford to be sleeping all day long!

Do All Animals Also Need 8 Hours Sleep As Humans?

Apart from asking which animal sleeps the most, people also ask about the amount of sleep animals need. While the average human needs a minimum of 7-8 hours of sleep, the number of hours that an animal needs depends on its species and behavior.

For example, horses are among the most active animals in the world during the day and can be seen grazing on grass or running around at full speed. They spend less than 3 hours in their resting state and have been observed to sleep for only 2-3 hours per day.

In contrast, cats spend more than half their time sleeping away from their human companionship, while dogs are more likely to sleep with their owners. Other animals that need less than 8 hours of sleep include bats (3-4 hours), cows (2-3 hours), sheep (2-3 hours), goats (2-3 hours), and chickens (1-2 hours).

Which Animal Sleeps The Most?


Koalas sleep for 18-22 hours a day, which is more than any other mammal. They sleep so much that they only need to drink water once every few days. This has led scientists to believe that koalas are actually hibernating. The animals’ body temperatures drop during the night, and their metabolism slows down significantly.

Koalas live in eucalyptus trees in Australia, where it’s hot and dry most of the year. They also eat mostly eucalyptus leaves, which contain high amounts of water and fiber but very little energy or nutrition. As such, koalas need to conserve their energy as much as possible—which means sleeping almost all day long!

Little Brown Bats

Little brown bats are some of the world’s longest-sleeping mammals, and they spend nearly 19 hours a day sleeping. They even sleep during the day—which is unusual for mammals—so that they can be active at night when it’s cooler outside.

These little guys are not only the longest-sleeping mammals in existence; they also have one of the best senses of smell out there. They use their sense of smell to hunt insects, which makes up most of their diet.

European Hedgehogs

The European hedgehog is a small creature with a lot of personality. They’re known for their quirky faces, prickly fur, and long snouts. But did you know that they sleep for 18 hours every day?

In fact, hedgehogs are among the most common animals to be kept as pets in Europe. They’re also easy to care for and can be trained to walk on leashes! But who knew that these cute little critters needed so much rest? It’s not just because they’re lazy—it’s because they have very thin skin that can tear easily if they run around too much or get into fights with other hedgehogs. So when they’re not out patrolling their territory (which is typically around one acre), they’ll often retreat into their dens to sleep.

Giant Armadillos

Giant armadillos sleep for 16-18 hours a day. They are omnivores and eat insects, small animals, fruit, and plants. Giant armadillos are not endangered or threatened by humans in any way. Their biggest threat is being killed as pests by farmers who think they will eat their crops or livestock.


When people ask which animal sleeps the most, they probably assume it’s the sloth. However, sloths sleep for about 14-16 hours a day, which is why they are rarely seen. The sloth’s long and slow digestive process is also responsible for their sluggish nature. They have very long intestines that break down food slowly, requiring them to digest their food over a period of several days.

The sloth’s body temperature varies with the ambient temperature, so they are most active when it’s warmest and sleep when it’s coldest. They are not as active in rainy weather because they can’t hang upside down on wet branches without slipping off. Sloths also have an extremely low metabolic rate which means they need less food than other animals of similar size.

It takes a sloth approximately five minutes to move from one tree to another and descend from the top of one tree to the bottom of another. Sloths can descend at speeds of up to 60 feet per minute and climb at about 25 feet per minute.

Is Animal Hibernation Different From Sleeping?

The answer is yes. Animal hibernation and sleeping are two very different states of being, but they do share some similarities. Both are characterized by a reduced metabolic rate, meaning that the animal’s body is using less energy than it would normally need to sustain itself.

However, there are several key differences between the two states. In order for an animal to go into hibernation, it must be able to lower its body temperature significantly enough to enable it to survive the colder temperatures of winter without expending too much energy. In contrast, when an animal sleeps, its brain does not need to slow down its activity as much as when it goes into hibernation.

This means that it can essentially “switch off” parts of its brain when it sleeps and still remain conscious; however, when an animal hibernates, its brain activity becomes so slow that it may not even be able to wake up if something happens around them while they’re asleep!

Do All Animals Hibernate?

Not all animals hibernate. Hibernation is a state of decreased metabolic activity during which animals enter torpor, a state of deep sleep. Hibernation is characterized by reduced body temperature and metabolic rate, which prevents the animal from using as much energy as it would otherwise need to stay awake and active. Some animals, such as bears, bats, and ground squirrels, are known to hibernate in order to survive the winter months when food is scarce.

Some animals do not hibernate. These include fish, amphibians and reptiles that live in warmer climates where food is available year-round or who can find sources of food any time of year. Some birds also do not hibernate because they migrate south for the winter months. In addition, insects do not hibernate because their bodies would dry up if they did so.


All in all, it’s amazing just how complex a topic of sleep can be. It can be studied from a variety of different angles, from the biological to the psychological. And depending on what you’re researching, you might uncover some fascinating facts. For example, did you know that there’s a type of bird that takes on a different type of nesting behavior when they’re sleep deprived? Or that humans are among the most sleep-deprived mammals out there? Who knew?
