Hello everyone 😇

In this article, you will learn why sleep is important for everyone.

Sleep accounts for one-fourth to one-third of the human lifetime. But what precisely happens when you sleep?

Prior to the 1950s, most people believed that sleep was a passive activity in which the body and brain remained still. "But it turns out that sleep is a period during which the brain is engaged in a number of activities necessary for life—which are closely linked to quality of life," researchers devote a significant portion of their waking hours to learning more about these processes and how they affect both mental and physical health. Here's a look at some of sleep scientists' key (and often surprising) results, as well as what they're currently discovering about sleep science.

All Sleep is not the SAME

During your sleep, your brain will alternate between two forms of sleep: REM (rapid-eye movement) and non-REM.

The cycle begins with non-REM sleep, which is broken down into four stages. The first stage happens between being awake and becoming asleep. The second type of sleep is light sleep, which occurs when the heart rate and breathing normalize as the body temperature decreases. The third and fourth stages are characterized by deep sleep. Though REM sleep was often regarded to be the most important sleep phase for learning and memory, new research suggests that non-REM sleep is more important for these processes, as well as the more restful and restorative portion of sleep.

As you enter REM sleep, the eyelids move rapidly behind closed lids.
 

Why You Need to Sleep

If you've ever felt sleepy after a bad night's sleep, you'll understand how critical sleep is for brain function. First, proper sleep is necessary for "brain plasticity," or the brain's ability to adapt to stimuli. If we don't get enough sleep, we can't process what we learnt throughout the day and will have a harder time remembering it later. Researchers also believe that sleep may aid in the removal of waste products from brain cells, which appears to be less efficient when the brain is awake.

Sleep is also required for the body's overall function. When people don't get enough sleep, their health risks rise. Symptoms of sadness, seizures, hypertension, and headaches.
