From the viewpoint of energy saving, one of the functions of sleep is to supplement the glycogen level of the brain that decreases during the awakening time. In line with this idea, humans and many other animals sleep at night. In addition, body temperature is a 24-hour cycle, reaching a minimum at night, reducing heat loss. From an energy-saving perspective, one function of sleep is to replenish glycogen levels in the brain, which decline during wakefulness. In line with this idea, humans and many other animals sleep at night. Nights are generally cold, so if you are nocturnal, you will need to consume more energy to keep you warm. All animals, including insects, must sleep. It's very different from humans and other mammals, but even in lower animals with little or no brain sleep. These animals have periods of inactivity, indicating less response to stimuli. There is no peculiar scientific opinion as to why organisms, including humans, have developed a need for sleep, as there are many things that have not yet been discovered. Evolution of Human Sleep Much of what is known about sleep development is still theoretical, but sleep is thought to primarily help restore and save energy. According to energy saving theory, sleep is necessary to save energy. Sleep makes it possible to reduce our calorie needs by spending some of our time functioning in lower metabolism. This concept is underpinned by how metabolic rates decrease during sleep.
Sleep has been observed in all animals studied so far by science and is as universal as energy intake throughout life. Studies have also shown that the bodies of various animals begin to break when they are continuously sleep deprived, and sleep is essential.
Why is sleep important for humans and animals?
Most animals have a natural circadian rhythm or an internal biological 24-hour clock that regulates sleep and wakefulness. For humans, sleep is essential for overall health. Above all, sleep allows humans to recharge, integrate memory, and repair the body. Young people also need sleep to grow properly.
Are there any animals that don't really need sleep?

Why do you need to sleep at night?
From the viewpoint of energy saving, one of the functions of sleep is to supplement the glycogen level of the brain that decreases during the awakening time. In line with this idea, humans and many other animals sleep at night. Nights are generally cold, so nocturnal activities require more energy to be consumed to keep you warm.
