10 Animals that Love Sleeping, Some Even Up to 22 Hours A Day!

Liputan6.com, Jakarta - Do you know that there are some animals that love sleeping a lot? Sleep is a way to restore oneself and replenish the energy that has been used. Some animals in the wild often sleep for a very long time, even for days, in a condition called hibernation. Hibernation allows animals to store food and save energy for months. There are also other animals that do not hibernate, but they enjoy sleeping for long periods of time, some even sleep for up to 22 hours a day!

Here are some species of animals that are very fond of sleeping, gathered from various sources, on Monday (27/4/2026).

Scientists have obtained valuable data on the sleep patterns of tree rats, which are commonly used as test subjects in research. Tree mice are fascinating creatures due to their rare habit of rarely leaving their nests at night, possibly because their eye structure is not suitable for daytime vision.

Squirrels gather food to hibernate during the winter, but they also sleep a lot outside of hibernation. Active during the day, squirrels sleep up to 15 hours every day. They also tidy up their nests for hibernation, only staying awake for 12-20 hours per week.

The fierce predator, the tiger, with its muscular body that requires a lot of energy, usually hunts at night. Despite sleeping for 16 hours a day, tigers can relax for up to 20 hours. Failing to hunt for one night can have fatal consequences, as tigers need to manage their energy efficiently.

The giant armadillo uses its hard shell to protect itself from various natural threats. They tend to hide most of the time, being able to stay in their burrows for 16-18 hours a day to search for food and rest. Researchers are still studying their sleeping patterns more closely, as giant armadillos are also active in searching for food within their burrows.

Night monkeys are active in the rainforests of Central America, where they have adapted to the dark environment by using their night vision to hunt and survive. Despite being called "owl monkeys" because of their unique ability, these monkeys are still agile and skilled at navigating the forest without light.

The python snake is one of the laziest snakes, capable of sleeping for up to 18 hours in a row. They are active at night to hunt for prey and then rest in a safe place. This long break is very important because they need a long time to digest their prey, which can take days or even weeks, depending on the size of their prey.

Small brown bats are active hunters after dusk and return to their sleeping places to rest. This rest helps them gather enough energy to survive. The small brown bat needs to consume food equivalent to half of its body weight every night, while adult bats can eat more than their entire body weight in one night of foraging. In addition, these bats also hibernate during the winter season.

Koalas, tree-climbing marsupials from Australia, suffer from chronic sleepiness due to their poor nutritional diet. Despite the tall branches protecting them from predators and providing abundant eucalyptus leaves, these leaves have little nutritional value, resulting in low competition among them. However, koalas are incredibly voracious during the four to five hours they are awake. They can consume up to one kilogram of white gum leaves every day and often store them in their cheeks to eat during their afternoon nap.

Sloths are often considered the laziest creatures in the world. While in captivity, they can sleep up to 20 hours a day, but research shows that wild sloths usually sleep less than 10 hours each night. Sloths are known for their unique habit of hanging on tree branches most of the time. Their unique body structure allows them to perform various activities such as giving birth, mating, eating, and sleeping while hanging.

Opossums do not sleep while hanging by their tails, as is often believed. Instead, they are nocturnal animals that hide in tree holes or rodent nests after finishing their hunting.
