Sleep is an essential function that allows our body and mind to recharge, leaving us refreshed and alert when we wake up. Sleep is also necessary for our health and wellbeing, and can help the body remain healthy and stave off diseases. Sleep is critical to our survival, just like food and water. Sleep helps the body in several ways, including restoring energy, releasing hormones and proteins, and supporting healthy brain function. Sleep also allows the brain to store new information and get rid of toxic waste. Sleep needs can vary from person to person, but experts generally recommend that adults get at least seven hours of sleep per night.

Sleep restores the brain's operating system to an optimal state
Sleep is a fundamental need, just like food or water. Without it, the brain cannot function properly, impairing our ability to concentrate, think clearly and process memories.
New findings from WashU researchers in biology and physics suggest that sleep helps restore the brain's operating system to a critical state. This is supported by a study published in Nature Neuroscience, which tracked the brain activity of sleeping rats. The study found that the brain needs to regularly reset its operating system to reach 'criticality', a state that optimises thinking and processing.
The brain is like a biological computer, and memory and experience during waking change the code bit by bit, slowly pulling the larger system away from an ideal state. The central purpose of sleep is to restore an optimal computational state.
Sleep is therefore essential for the brain to function properly and reach an optimal state.

Sleep is a fundamental need, like food and water
Sleep is a fundamental need, just like food or water. “You’ll die without it,” said Keith Hengen, assistant professor of biology. Sleep helps the brain to function properly, and without it, our ability to concentrate, think clearly and process memories is impaired.
Hengen and a team of Arts & Sciences researchers have constructed a theory that melds concepts from the fields of physics and biology to explain the meaning of sleep and the complexity of the brain. According to their research, the brain needs to regularly reset its operating system to reach 'criticality', a state that optimises thinking and processing.
The brain is like a biological computer, Hengen said. "Memory and experience during waking change the code bit by bit, slowly pulling the larger system away from an ideal state. The central purpose of sleep is to restore an optimal computational state".
Sleep is therefore essential to our ability to function, and a lack of sleep can have serious consequences on our health and well-being.

Sleep helps us concentrate, think clearly and process memories
Sleep is a fundamental need, just like food or water. Without it, the brain cannot function properly, impairing our ability to concentrate, think clearly and process memories.
According to a study published in *Nature Neuroscience*, the brain needs to regularly reset its operating system to reach a state of 'criticality', which optimises thinking and processing. The brain is like a biological computer, and sleep is what restores it to an optimal computational state.
This is supported by findings from WashU researchers in biology and physics, who found that sleep helps restore the brain's operating system to a critical state.
Sleep is essential for our ability to concentrate, think clearly and process memories.

Sleep is linked to the complexity of the brain
According to a study published in Nature Neuroscience, sleep helps the brain to regularly reset its operating system to reach 'criticality', a state that optimises thinking and processing. The brain is like a biological computer, and memory and experience during waking change the code bit by bit, slowly pulling the larger system away from an ideal state. The central purpose of sleep is to restore an optimal computational state.
By melding concepts from the fields of physics and biology, researchers have constructed a theory that could explain both the meaning of sleep and the complexity of the brain.

Sleep is linked to the meaning of life
Sleep helps restore the brain's operating system to a critical state, according to new findings from WashU researchers in biology and physics. They tracked the brain activity of sleeping rats to make the case that the brain needs to regularly reset its operating system to reach "criticality", a state that optimises thinking and processing.
