6 amazing things your body does while you sleep

While other parts of your body rest during sleep, your brain remains active. One of the most important jobs your brain does at night is getting rid of the information you don't need anymore, such as useless details about your daily routine.

At the same time, your brain is aware of what you do need to know, so after it does all the sorting at night, you usually remember important facts better.

When you sleep, you simply don't interrupt the process of losing extra pounds with eating or drinking. Your digestive system rests, which helps your body to cleanse and regulate hunger hormones. That's why when we don't get enough night sleep we tend to overeat.

When we sleep, small proteins known as cytokines are released by our immune system. When we're injured or sick, these macromolecules help our organism deal with inflammation, infections and injuries. For your immune system to function correctly, getting enough sleep is also vital.

It's one of the most bizarre ways our body takes care of itself. In order for us not to get hurt while physically acting out our dreams, our muscles get temporarily paralyzed when we see them.

Most often it happens when we shift from one stage of sleep to another. These awakening are too brief for us to remember them in the morning.

Your skin cells are regenerating only when you sleep, and collagen – the most important collagen that makes your skin look younger and healthier – is also produced during sleep. Long-standing sleep deprivation often results in acne and premature aging.
