Things Your Brain Does While You Sleep

While you are sleeping you may not be fully aware. But actually at the time of sleep, our brain still perform activities necessary for the body. The full sleep cycle will take about 90-120 minutes in full, so the average person will undergo four or five sleep cycles in normal time.

A study at the University of California at Berkeley in 2007 found that sleep can combine information gained during the day before falling asleep and asleep.

And here are the things your brain does when you're sleeping, quoted from Reader's Digest.

1. Perform cleaning

A 2013 study from the University of Rochester Medical Center found that the waste disposal system in the brain will be active during sleep, which can clear toxins in the brain that if stacked can cause problems.

According to Sleep Science, cerebral spinal fluid is pumped faster throughout the brain while you sleep, removing protein detritus that can cause Alzheimer's and dementia over time.

2. Make and strengthen memories

Matthew Walker, PhD, a sleep researcher at the University of California, Berkeley, told the National Institutes of Health: "Sleep after study is essential to help save and reinforce the new information into brain form, meaning that you are less likely to forget about that information In other words, if you face the test it might be more beneficial if you take a nap. "

3. Restoring energy

Your brain and body need a good night's sleep to restore their energy. It also explains why you will overeat when you are not getting enough sleep because lack of sleep can raise a hormone hunger called ghrelin.

Worse, your energy shortage will push your brain to look for high-calorie fast foods like donuts, bread, and other simple carbohydrates.

4. Helps make decisions

A study published in the journal Current Biology found that the brain processes difficult problems during sleep, helping you make a decision after waking up.

5. Makes you unable to control the body

Once your body enters a deep sleep stage, your brain will feel very relaxed which can cause you to behave strangely asleepwalking or talking during sleep.

According to the National Sleep Foundation, abnormal sleep activity increases during sleep deprivation, so make sure you get the seven to eight hours of sleep time it takes if you start doing weird things while asleep.

6. Your creativity increases

A study at the University of California at Berkeley in 2007 found that sleep can combine information gained during the day before falling asleep and asleep. In fact, 33 percent of people are more likely to be creative after sleep.
