Sleep is essential for the brain to function normally. Lack of sleep can hinder memory recall and elevate stress levels. Sleep is needed to regenerate parts of the brain, and without it, neurons can malfunction, affecting a person's behaviour and performance. Sleep is also vital for the rest of the body, impacting everything from the heart and lungs to metabolism, immune function, mood, and disease resistance.

What You'll Learn
Sleep is needed to regenerate parts of the brain
Certain stages of sleep are needed for the regeneration of neurons within the cerebral cortex, while other stages seem to be used for forming new memories and generating new synaptic connections. Sleep may also promote the removal of waste products from brain cells, which seems to occur less efficiently when the brain is awake.
Research suggests that a healthy amount of sleep is seven to eight hours per night for most people, with teenagers needing about nine hours and younger children needing more. Sleeping allows us to reduce our caloric needs by spending part of our time functioning at a lower metabolism. The restorative theory states that the body needs sleep to restore itself, allowing cells to repair and regrow.

Lack of sleep can hinder memory recall
Sleep is vital for the brain to function. Research has shown that a lack of sleep can hinder memory recall and elevate stress levels. Sleep is needed to regenerate parts of the brain so that it can continue to function normally. If we don't get enough sleep, some neurons in our brain can malfunction, which affects our behaviour and performance.
The brain's ability to adapt to input is called 'brain plasticity', and a healthy amount of sleep is vital for this. If we don't get enough sleep, we are unable to process what we've learned during the day and have more trouble remembering it in the future.
The restorative theory of sleep states that the body needs sleep to restore itself, allowing cells to repair and regrow. Sleep is also believed to promote the removal of waste products from brain cells, which occurs less efficiently when the brain is awake.
Most people need seven or eight hours of sleep per night to function efficiently. Teenagers need about nine hours, and younger children need more.

Sleep is vital for brain plasticity
Sleep is also thought to promote the removal of waste products from brain cells, which occurs less efficiently when the brain is awake. Sleep is therefore necessary for the brain to function normally, and most people need seven or eight hours of sleep per night to function efficiently. Teenagers need about nine hours, and younger children need more.
The restorative theory of sleep also states that the body needs sleep to restore itself, and that sleep allows cells to repair and regrow. Sleep affects almost every type of tissue and system in the body, from the brain, heart and lungs to metabolism, immune function, mood and disease resistance.

The restorative theory of sleep states that the body needs sleep to restore itself. Sleep allows cells to repair and regrow, and it is during sleep that the brain's metabolic rate drops.
