Why We Need to Sleep

why need to sleep

Have you ever wondered why humans need to sleep? “Humans need rest”, you might say. Yes, but this is too general. Maybe we can go a little deeper. This article will give you an in-depth look at why we need a certain amount of sleep time every day.

1. Synthesized energy.

Firstly, you need to know that the brain consumes 20% of the body's energy, and where does that energy come from? It is continuously synthesized and accumulated when you at sleep. If you stay up too late and don’t get enough sleep, the glycogen that needs to be consumed the next day is not enough, so there is not enough energy to support you in efficient work and study.

2. Clean up metabolites.

After a day of work and study during the day, the brain also produces a lot of metabolic waste. If not cleaned up in time, it can damage the brain. During the day, the brain devotes all its energy to your daily activities, while it starts cleaning up harmful substances at night.

A 2012 study found that cerebrospinal fluid in the brain removes metabolic waste products such as beta-amyloid during sleep. The beta-amyloid was shown to have toxic effects on brain neurons and has been linked to neurodegenerative diseases such as Alzheimer's. The brain's cleansing system is most active during sleep. The brain uses maximum energy to process all kinds of sensory information when you wake up. And when you at sleep, the brain's waste-removing system becomes active as the nerve centers that process information become less active.

3. Enhance memory.

The brain strengthens memory traces and vocabulary integration during sleep. During sleep, the cerebral neocortex and hippocampus accomplish memory transfer through Memory Consolidation to form long-term memory. In addition, it is almost common sense that the brain preferentially synthesizes growth hormone during sleep.

In general, according to the current research, sleep brings us the following benefits: energy recovery, metabolic regulation, thermoregulation, immune system enhancement, waste removal, brain maturation, circuit reorganization, synapse optimization, risk aversion, etc. These functions are mainly manifested in two aspects. On the one hand, it consolidates memory and maintains the cognitive function of the brain; On the other hand, cleaning and optimization keep the brain healthy and efficient.
