How Does a Squirrel Sleep?
We all wonder how a squirrel sleeps, but few people understand the secret behind it. Squirrels spend up to 18 hours a day sleeping. They close their eyes to block out light, and keep them closed for that reason. Otherwise, the light would trigger them to wake up, preventing them from getting a good night’s sleep. So, what really happens when a squirrel closes its eyes to sleep?

Baby squirrels sleep in a drey
A drey is a small, round, or square box where baby squirrels sleep. It is typically constructed in a tree branch, and contains a mixture of twigs, leaves, and moss. Nests are made in tree branches that are about 30 feet off the ground. Squirrels usually build several dens in a tree, so that each one can be used for a different purpose. During the winter, squirrels often build their dens in tree trunks or in the forks of a tree.
Adults sleep 18 to 20 hours a day
Squirrels sleep between eight and twenty hours a day, but their sleeping time varies considerably. Most sleep at night while others prefer to stay up for the day. This means that the sleep time of a squirrel depends on how active the animal is during the day. During the winter, squirrels sleep for more than eighteen hours. However, if you’re interested in getting a squirrel as a pet, it’s better to know when they sleep.
Ground squirrels go into torpor to escape heat
To study how ground squirrels go into torpor, researchers examined the onset of heterothermy (heat-related physiological processes) in 13-lined individuals. These animals undergo the transition from summer to winter during the critical period of their circannual cycle. Data from implanted data loggers of 57 animals was analyzed to determine whether they were expressing torpor. The onset of torpor was defined as two consecutive data points with a temperature of 32 degC or higher.
Squirrels sleep in their dens
Tree squirrels build dens in trees, where they can store food. Unlike cavity nests, tree squirrels can conserve energy and protect their young from the elements in a den. Tree squirrels spend long winters in dens, while the drays they build in bushes and other areas of the forest are warmer. Different squirrel species sleep in different den types, depending on the climate in their area.
They nap during the day
If you want to know more about squirrels, you should read the Ultimate Guide to Squirrel Nests. There are three major types: flying squirrels, ground squirrels, and tree squirrels. All three spend more than eight hours sleeping during the day. Their sleeping habits vary based on their age. Baby squirrels tend to sleep for about six weeks before opening their eyes and spending time outside their nests.
They hibernate
If you’ve ever wondered how squirrels hibernate, you’re not alone. Many animals, including squirrels, hibernate for months or even years. Ground squirrels, for instance, need a burrow or den to hibernate. The cold temperatures can cause them to freeze to death, and they need to conserve energy by slowing down their metabolism and reducing energy-consuming activities. They build up fat stores to keep themselves warm.
They sleep with their eyes closed
Did you ever wonder why squirrels sleep with their eyes closed? The reason they do is because it helps them protect their eyes. Not only does closing their eyes protect them from light and dust, but it can also prevent insects from getting into the eye during the night. And, of course, it keeps them from waking up at the first sign of sunlight. A squirrel’s eyes are so delicate that even the smallest particles can damage the tissue.
