Difference Between Sleep And Hibernation

Winter is an unevenly warm season characterized by low body temperature, slow breathing and heart rate and low metabolism. In this case, animals conserve more energy during sleep. In contrast, sleep is driven by an internal circadian clock primarily at night for diurnal animals, and during the day for nocturnal animals.

Another important difference between hibernation and hibernation is that all metabolic activity is shut down or at least significantly slowed down. For example, a hibernating bear neither poops nor defecates. Instead, the body reabsorbs digested material to conserve nutrients.

Difference Between Sleep And Hibernation

Let’s take a closer look at the most important difference between sleep and sleep.

What is Hibernation?

Hibernation is a physiological response used by organisms during stressful times, especially during long, cold winters. There is a kind of sluggishness and misery in the metabolism of organisms.

As the outside temperature drops during the summer, the body temperature of most reptiles and amphibians in the water decreases. This forces them to go to the extreme depths of the pools and hide for a long sleep under the mud.

This is known as hibernation. When the temperature rises outside and their body temperature returns to normal, they emerge from their long hibernation. For example, bears, locusts, etc.

However, some organisms simply adapt, while others migrate or move to better locations. A good example of this is zoo animals: even when winter sets in, zoo animals do not hibernate because they have a constant source of food and water and their rooms are temperature regulated. Therefore, there is no need to conserve energy, and thus we give up hibernation.

What is Sleep?

Sleep is found in most mammals, birds, reptiles, etc. It occurs in response to the circadian clock. Circadian rhythms determine our sleep patterns. The biological body system has a 24-hour cycle. During sleep, all metabolic processes occur at the same rate.

Difference Between Sleep And Hibernation



Respiratory rate

It is reduced It goes down drastically compared to sleep

Body temperature

May be regulated according to their surrounding ambient temperature Considerably lower, sometimes reaching 0°C

Rate of heartbeat

Is lowered Very low and this is essential to reduce the metabolic rate during hibernation

Time Duration

Sleep duration is shorter than hibernation Duration of hibernation is much longer, often months together

Metabolic rate

The metabolic rate is unaffected The metabolic rate slows down considerably to conserve energy


The digestion process is unaffected Digestion process stops and both urine and faeces are reabsorbed to preserve and utilize nutrients
