What is the difference between winter sleep and hibernation

This is a physical phenomenon in which an animal lowers its metabolism and body temperature so they can survive through months of cold weather. For example, during hibernation, a ground squirrel will drop to a body temperature of 28 degrees F. Other animals, like frogs or snakes, have a naturally occurring antifreeze that flows through their system to help avoid freezing—in the same way, our vehicles operate in winter months.

In terms of slowing metabolism rates, a bat can lower its heart rate to 11 beats, down from an awe-inspiring bpm when they are in active mode.

Hibernation can be achieved for a month or two, or for half the year, depending on the species and habitat. In order to avoid starving to death during hibernation, animals must store excess body fat that is burned off while in hibernation mode. Another interesting fact: if an animal is woken up while in hibernation, they can die due to the sudden change in body functions. We all know that bears hibernate, but actually, not all bears hibernate. Earth Rangers says that only four types of bears actually hibernate: brown bears, polar bears, Asiatic black bears, and the American black bear.

By the way, brown bears include grizzly bears, so these too are hibernators. But what about other types of animals that hide out for the winter months? During sleep most of the body's systems are in an anabolic state, that heals the muscular, skeletal and nervous systems.

A well-known feature of sleep is the dream which resembles waking life while in progress. Sleep is a vital process that maintains mood, memory and cognitive functions, and plays a large role in the function of the endocrine and immune systems.

In sleep, humans perceive fewer stimuli, also 'sleep' helps to restore energy. As discussed earlier sleep is divided into two broad categories- rapid eye movement sleep and non-rapid eye movement sleep. REM sleep, also known as paradoxical sleep, is a smaller portion in your good night's sleep; it is the primary occasion for dreams or nightmares.

Hibernation is a physiological response that can be seen in endothermic animals, especially during winter, characterized by low-body temperatures, slow breathing and heart rate and low metabolic rate for limited resources. Hibernating animals can drop their body temperature nearly to 0 o Celsius. These animals are under a state of torpor and cannot be aroused easily. Hibernation, like sleep, begins with a non-REM stage.

The equivalent of hibernation in the summer months is aestivation. Obligate hibernators such as ground squirrels, rodents, mouse lemurs, go to hibernation spontaneously regardless of ambient temperature and access of food.

Well, maybe we should have been born as bears. Bears are the most notorious animals for taking season-long snoozes every winter, but a surprising number of animals also have some interesting winter slumber styles, too.

Animals do this to survive the winter because the weather is cold and food is scarce. It is advantageous because these animals can quite literally shut themselves off for weeks at a time rather than try and survive through harsh weather conditions.

While many people think bears are hibernators, they actually participate in a similar, though not exact, practice. Instead of hibernating, bears fall into a deep sleep called torpor. During torpor, heart rate and breathing rate decreases, body temperature reduces slightly and bears do not eat or release bodily waste.

Bears can sleep more than days without eating, drinking, or passing waste! Instead, bears are able to literally turn their pee into protein through a urea recycling process.
