Deep sleep VS light sleep

It is well known that lack of sleep is highly correlated with diseases such as Alzheimer's, cardiovascular disease, stroke, and diabetes. But did you know what sleep does to your mental state? Sleep deprivation leads us to make hasty, risky decisions and our ability to empathize with others decreases. Plus, lack of sleep can make us more sensitive to our own pain.

There are three stages of sleep: light sleep, rapid eye movement, and deep sleep. During light sleep and REM, our brain waves are nearly identical to our waking brain waves, but during deep sleep our brain waves are long pulses that are quite different from our waking brain waves.

After the human body enters the sleep state, there will basically be two levels of changes. The first is the physical level. When the body is stretched, the muscles will be in a completely relaxed state, and the body functions will get a rebound. The second is the level of the brain. The cerebral cortex is in a state of internal inhibition, that is, the cerebral cortex that receives the heavy workload of uploading information from the nervous system of the whole body during the day begins to recover and soothe when you fall asleep.

Deep sleep allows us to convert our daytime experiences into long-term memory, knowing that as we age we will most likely no longer have these regenerative brain waves. It can be said that deep sleep and brain waves are a major sign of physiological youth.
