Many of us also think that sleep is a passive, constant and unchanging process. Yet, what we don’t realize that sleep is in fact a very active state. Our bodies move frequently during the night, but what’s even more striking is that our brain activity is more varied than it is when we are awake. As we sleep our body goes through what is called a non-Rem and Rem sleep.

But the bottom line is that everybody needs sleep - it is as essential as breathing and eating. Yet, despite decades of study, scientists still do not know why we do it. However, there are some intriguing clues and theories. One obvious clue is that we all feel better after a good night’s sleep, and much worse if deprived of a decent night’s rest. In humans the need for sleep gets so strong after a few days that nothing will keep you awake – with reports of people falling asleep standing up, even whilst being kicked or having intolerably loud music played at them.
Diet plays a big part in sleep; the body needs the nutrients to properly accomplish the organizational tasks in the brain.

It seems that our brain is designed to collect knowledge during daytime and analyze them at nighttime. Some studies mentioned in the article show why humans need a minimum of six hours of sleep in order to have better performance in daily activities. What remain to be undetermined is the chemicals involved in this process, or how our brain can process information while we are unconscious. The truth is that researches clearly demonstrate that our brain is active during sleep and that this process is more complex than we think. Before reading this article, I thought that while we slept our brain simply in a “resting” stage.
The first reason why staying up all night, cramming, is a mistake is because insufficient sleep decreases the ability to remember any new information. Studies show that the brain needs several hours of sleep to solidify the information it’s learned during the day. “Sleep serves not only a restorative function for adolescents’ bodies and brains, but it is also a key time when they process what they’ve learned during the day” (National Sleep Foundation 484). Depriving the brain of sufficient sleep can cause one to be fatigued, disoriented, and even delusional. One needs the recommended amount of sleep in order to prepare and perform well on an exam, which is the primary achievement for students.
