Sleep is a necessity for all animals with complex brains, and it is widely accepted that sleep supports the formation of long-term memory and the retention of information. Despite this, the exact reason why humans and animals need sleep is not known. In his 2017 book *Why We Sleep*, Matthew Walker discusses the importance of sleep, the side effects of not getting enough, and its impact on society. Walker asserts that sleep deprivation is linked to numerous fatal diseases, including dementia.

What You'll Learn
Sleep deprivation
Sleep is extremely important to human health and well-being. Humans and animals need sleep, but we do not know exactly why. Everyday activities, one's appearance, and how one expresses oneself all rely on this necessity. If one is tired from not getting enough sleep, one will not be able to function properly in common activities. Sleep deprivation leads to struggling to remember information, altering one's mood, energy, health, focus and a number of other effects. Sleep deprivation can even be used as torture.
Sleep has the ability to retain memories and amend the abilities of human learning. Many organisations who value creativity, productiveness and resilient workers, give them a "sleep bonus", with the amount of extra sleep received being determined through electronic monitoring.
It has been widely accepted that sleep must support the formation of long-term memory, and generally increase previous learning and experiences recalls. However, its benefit seems to depend on the phase of sleep and the type of memory.

However, its benefit seems to depend on the phase of sleep and the type of memory. Sleep is observed to be a necessary behaviour across most of the animal kingdom, including some of the least cognitively advanced animals, implying that sleep is essential to the most fundamental brain processes, i.e. neuronal firing.

Sleep is vital to the most fundamental brain processes, such as neuronal firing, and is essential for the formation of long-term memory and the recall of previous learning and experiences.
The importance of sleep to human health and well-being is well-established. Sleep-deprived people struggle to remember information, and experience changes in mood, energy, health, focus and a number of other effects. Sleep deprivation can even be used as a form of torture.
Some organisations that value creativity, productiveness and resilient workers offer a "sleep bonus" to employees, with the amount of extra sleep received being determined through electronic monitoring.
The book *Why We Sleep: The New Science of Sleep and Dreams* by Matthew Walker, an English scientist and the director of the Center for Human Sleep Science at the University of California, Berkeley, discusses the importance of sleep, the side effects of failing to get enough, and its impact on society. Walker spent four years writing the book, in which he asserts that sleep deprivation is linked to numerous fatal diseases, including dementia.
