Israeli scientists from Bar-Ilan University have discovered a previously unknown function of sleep that may explain why all complex organisms with a brain need it. The research, published in Nature Communications, suggests that sleep allows nerve cells to perform 'maintenance' tasks needed for nuclear maintenance and brain performance. This includes clearing out DNA damage accumulated during waking hours. The findings could explain why sleeplessness leads to death and why sleep is so universal, even though it makes us vulnerable to predators.

Sleep allows nerve cells to perform 'maintenance' tasks needed for nuclear maintenance and brain performance
Sleep allows nerve cells to perform maintenance tasks needed for nuclear maintenance and brain performance. Researchers at Bar-Ilan University in Israel have discovered that sleep allows nerve cells to take a break from their usual function, freeing up resources to perform 'maintenance' tasks that are vital for nuclear maintenance and brain performance.
The discovery explains why sleep is so fundamental to all complex organisms with a brain. It also sheds light on why sleeplessness ultimately leads to death.
On a cellular level, sleep increases chromosome dynamics that clear out DNA damage accumulated during waking hours. This is important because sleep deprivation causes some kind of gradual systems collapse in the brain.
The Israeli scientists' findings were published in the journal *Nature Communications*. The research presents a groundbreaking theory that may explain why the behaviour is so universal and essential to all organisms with a nervous system, including invertebrates.

Sleep increases chromosome dynamics that clear out DNA damage accumulated during waking hours
The Israeli scientists have uncovered a previously unknown function of sleep that may explain why the behaviour is so fundamental to all complex organisms with a brain. Sleep has remained universal and essential to all organisms with a nervous system, including invertebrates.
The study, published in *Nature Communications*, presents a groundbreaking theory: that when we sleep, our nerve cells take a break from their usual function, freeing their resources to reduce DNA damage that was accumulated during wakefulness.

Sleep deprivation causes a gradual systems collapse in the brain
The Israeli scientists have therefore concluded that sleep is biochemically essential. Their research has shown that sleep deprivation causes some kind of gradual systems collapse in the brain.
This is supported by the fact that it is well-established that the loss of sleep affects brain performance, including memory and learning, from fruit flies to humans.
The need for sleep is universal. From jellyfish to frilled-neck lizards to flying squirrels to humans, all complex organisms with a brain need sleep. Sleep has remained essential throughout evolution, even though it makes no evolutionary sense. This is because when we sleep, we are more vulnerable to predators.

Sleep is universal, even though it makes no evolutionary sense
Israeli scientists from Bar-Ilan University have discovered that sleep is essential for nuclear maintenance and brain performance. Sleep allows our nerve cells to take a break from their usual function, freeing up resources to repair DNA damage accumulated during the day. This repair is essential for brain performance, including memory and learning. Without it, we experience a gradual systems collapse in the brain.
The study, published in *Nature Communications*, explains how sleep is fundamental to all complex organisms with a nervous system. It also sheds light on why we need to spend a third of our lives asleep.
