Sleep is a crucial aspect of our daily routines, yet many of us may not fully understand the science behind it. In this article, we will explore the fascinating ways in which our brain heals and restores itself during rest.

There are four stages of sleep that our bodies cycle through during the night. These stages include non-REM sleep and REM sleep, each serving a different purpose in the process of healing and restoration.
Non-REM Sleep
During non-REM sleep, our bodies focus on physical restoration. This is the time when muscles repair themselves and energy stores are replenished. It is also a time when the brain consolidates memories and processes information from the previous day.
REM Sleep
REM sleep, on the other hand, is when our brains focus on emotional restoration. This stage is essential for maintaining cognitive function and emotional well-being. It is during REM sleep that our brains are most active and dreams occur.
The Role of Neurotransmitters

Neurotransmitters play a crucial role in the process of sleep and restoration. One such neurotransmitter is adenosine, which builds up in the brain throughout the day and signals to the body that it is time to rest. Other neurotransmitters, such as dopamine and serotonin, help regulate our sleep-wake cycles.
