Poor sleep increases the risk of Alzheimer’s in the later stages of life.

Benefits of Good Sleep

The hormone melatonin, which is released at night, causes people to fall asleep. Though it does not help you rest, it acts as a signal to regulate the circadian rhythm, or the sleep-wake cycle. It is the body’s internal clock that tells when to go to bed and when to wake up.
During the transition from wakefulness to sleep, you alternate between two types of sleep. REM (Rapid eye movement) sleep occurs during this period, during which vivid dreams appear, and there is increased brain activity. NREM sleep (Non-rapid eye movement) is where the body does the regenerative work. This sleep is further divided into four stages 1, 2, 3, and 4, with the numbers showing the order and depth of sleep. As you sleep, the mind and body undergo many changes that help in the regeneration of tissues, restoring energy levels, and recalibration of brain collections. At different stages of sleep, different functions are repaired or restored.
So each stage of the sleep cycle is important. The process is complex, but the benefits are many, with only a few of them being understood after various studies. But what is apparent is that a good night’s sleep is highly beneficial for the body’s biological functions. Some of these are listed below:
