What Happens when we are in sleep?

While asleep, you cycle through periods of non-rapid eye movement sleep (NREM) and rapid eye movement sleep (REM). It’s during REM sleep that we have the most vivid dreams. During this stage, your muscles are temporarily paralysed, meaning you can’t move.

Sleep serves to reenergize the body’s cells, clear waste from the brain, and support learning and memory. … Most of the sleeping we do is of the SWS variety, characterized by large, slow brain waves, relaxed muscles and slow, deep breathing, which may help the brain and body to recuperate after a long day.

When you sleep, there are less demands made on your heart. Your blood pressure will drop and your heart will be able to take a break. Sleep also causes the body to release hormones that can slow breathing, and relax other muscles in the body. This process can reduce inflammation and assist with healing.

Our bodies all require long periods of sleep in order to restore and rejuvenate, to grow muscle, repair tissue, and synthesize hormones. How Much Sleep Do We Really Need? Healthy sleep is critical for everyone, since we all need to retain information and learn skills to thrive in life.
