Elephants are the largest land mammals that currently exist, even so, they do not cease to impress with their size, as well as the strength they possess. These beautiful mammals also stand out for their intelligence, since it has been proven that they have a complex communication system that is part of the social structure, which is mainly made up in a matriarchal way, that is, by several females, their offspring and, to a lesser extent, measure, some males with whom they associate especially in the reproductive seasons.
However, the aforementioned is not the only curious fact, as there are various curiosities related to the life of these animals and in this Best Pets Lover article, we want to present one of them: their way of sleeping. Dare to continue reading and find out how much and how elephants sleep.
Do you want to know How Elephants Sleep? Don’t miss the following Best Pets Lover article in which we will explain everything you need to know How Do Elephants Sleep?
How long do elephants sleep?
Just like humans, all animals need sleep, since sleep is a biological necessity. Although some aspects are still little known by science, it is known that part of its importance lies in the fact that it offers a time of rest and recovery for the whole organism, essential to correctly maintain all its functions.
Now, not all animals need to sleep the same amount of time, some sleep much more than others and there is an inverse relationship between the size and amount of sleep of an animal. This is particularly evident in herbivores, who need to spend many hours a day eating to meet their nutritional requirements. In the case of elephants, it has been shown that there is a difference between those that are in captivity and those that inhabit natural spaces.

Thus, elephants living in captivity sleep between 3 and 7 hours a day, while free elephants only sleep a couple of hours a day. However, the latter can even go up to 46 hours in a row without sleeping. Generally, the latter occurs in the matriarchs or leaders of the group, who, in addition to guiding the herd, are responsible for monitoring and communicating any dangerous situation.

Scientists believe that the few hours of sleep that elephants have in the wild is due to two main reasons:
- On the one hand, the need to locate and consume food (remember that they are animals that weigh tons), so they require a daily intake of large amounts of plant matter.
- On the other hand, they need to be alert to the dangers they are exposed to in natural habitats. Although they are animals that have both large bodies and a lot of strength, as an adult individual it is not so easy for a predator to defeat him unless he is injured or sick, elephants live in herds and there are usually newborns or little ones to take care of because they are vulnerable to attacks.
Apart from the above, and regardless of how long the elephants sleep, they do not do it continuously either, but rather they do it in fragments of time. In this way, although they are resting, at times they can also be on alert.
Undoubtedly, all these aspects related to the dream of elephants have to do with biological conditioning that seeks to guarantee the survival and maintenance of the species.
Do elephants sleep together?
Elephants don’t sleep together and they don’t even sleep at the same time. This dates back to their vigilance against predators. In a group of elephants, you will discover a few elephants conscious around evening time, while some are about to rest and others are simply awakening.
Since elephants don’t sleep very long anyway, you’ll never find a time when all the elephants are asleep. If an elephant is asleep and there is a noise in another cage (at the zoo), the elephant will quickly jump up and stay awake. So elephants are light sleepers.
Do elephants sleep standing up or lying down?
Are you wondering if elephants sleep standing up or lying down? Elephants can rest both standing up and resting. However, this can also vary if they are in captivity or the wild since in captivity they tend to do it lying down more than in the wild, where they generally do it standing up.
Now, how do elephants sleep? During the sleep phase known as REM (Rapid Eye Movement), which lasts 25% of the total cycle, mammals are unable to move (although there may be alterations and movements do occur) and the muscles are quite relaxed.
Well, scientists estimate that elephants enter this sleep phase to a lesser extent because it would be impossible for them to do so while standing up, since, as we have mentioned, the body is immobilized and muscle strain would not allow this position. In this sense, it is when elephants sleep lying down that they enter the REM phase.
A curious fact about this stage is that experts estimate that both the storage of memories and learning take place during the REM phase, which is also when dreams are also made. Although elephants barely enter this phase, they are known for their excellent memory. Although there are debates about whether it is possible to talk about intelligence in animals, we believe that they are capable of qualifying themselves in this way, so elephants are undoubtedly very intelligent animals.
Do elephants sleep during the day or at night?
Elephants usually sleep at night, although this does not prevent them from sleeping during the day, especially in those individuals who have spent a lot of time awake. They are animals that travel long distances in search of food and water, so they usually make long journeys during the day and take breaks at night, but it is common for the pack leader to remain alert while the group sleeps.
On the other hand, where do elephants sleep? It is important to mention that conditions such as temperatures, wind, and humidity can influence the places where elephants sleep. Although they usually rest in different areas due to the long mobilizations they carry out, in some cases, they are faithful to certain spaces and return to them.
There is still a lack of studies to verify certain aspects related to the sleep of elephants and to know if the investigations carried out so far offer generalized data or data that can be extrapolated to all these animals. However, with the data obtained so far, we can get a slight idea of how elephants sleep.
Elephants are the mammals that sleep lest
A group of researchers from the University of Oxford conducted a study on the activity in two wild, free-roaming African elephants. They studied their behavior in their natural habitat, using an activity clock that measured their location.
The researchers found that the two female elephants were polyphasic sleepers: that is, they had an average daily total sleep time of about two hours, mainly between 2 and 6 a.m., and displayed the shortest daily sleep time of any mammal. registered to date.
Regarding their sleeping position, it could be seen how these two female elephants slept both standing up and lying down, however, they did not usually lie down too much: approximately every three or four days they had these periods of sleep in which they slept lying down, but it was not habitual in his rest. This limits your ability to enter REM sleep daily.

In the study, the researchers also noted on up to five occasions that female elephants went without sleep for up to 46 hours and traveled around 30 kilometers in 10 hours, possibly due to disturbances such as possible predation or poaching events.
After a night without sleep, the elephants also did not exhibit any form of sleep recovery. Regarding conditions for falling asleep, the study found that both ambient air temperature and relative humidity predicted sleep onset in elephants.
Do pachyderms dream?
The elephants slept on their feet most of the time and only lay down every three or four days and about an hour. Researchers believe this could limit their ability to enter REM sleep, indicating that they don’t dream every day as we do, but they can from time to time. Although this phase is thought to be important for memory consolidation, the new findings do not agree with that hypothesis, as elephants do not go through it every day and are known for their good long-term memory.
As for schedules, these animals slept especially before dawn. The information shows that ecological circumstances, like temperature and moistness, yet not daylight, are connected with when elephants rest and when they awaken, says Manger.
Understanding how various creatures rest is significant for two reasons: Firstly, it assists us with grasping the actual creatures and revealing new data that can assist with growing better protection techniques, and secondly, knowing how Different animals sleep and why they sleep in their way helps us understand how humans sleep, why we sleep, and how we might get a good night’s sleep.”
