why sleep

Everyone needs sleep. Everything needs sleep. But why sleep?

Last year I took Biology as a class and we learned about the brain and how it works. There are many different parts of the brain we learned about and altogether it was really interesting because no one ever has learned about how the brain really works.

However researchers and scientists tell us some information about how the brain works for example, the right side controls the left side of your body and the left side controls the right side of your body. That’s freaky-weird I think. One brain exercise/experiment that we held in biology last year was this: have one person cross their arms and have the palms of their hands facing eachother, then fold their hands and inter-twine their fingers. Then you can try having them close their eyes or just keep them open. Then have a second person rapidly tell them, “right ring” or “middle left”, “left pinky”, “right pointer” and have the person with folded hands lift up that finger. It truly is difficult trying to make sure you lift the right finger because you feel the opposite finger resting on the back of the other hand which confuses the brain, taking you longer to process what muscles to use because the nerves in your hands and from what you see are getting mixed signals!

Also in biology last year, we were assigned to research any newspaper or magazine article, and the topic was that it had to be about the brain, since we were then studying about the brain. I researched online and found that when we sleep, our brains clean themselves! While we sleep our brains become like “biological dishwashers”, as The Guardian says. Cerebral Spinal fluid is pumped around the brain, and flushes out waste products, which is why when you wake up in the morning, you usually have to go to the bathroom.

Teenagers most often need around 8 1/2 to an average of 9 1/2 hours of sleep per night, just enough to have enough energy for their bodies and minds for the next school day. If we don’t get enough sleep every night, we wake up less prepared to make decisions, concentrate, or be fully awake and prepared for what is to come for the next activity or school day.

I think this topic about the brain and how the brain needs sleep is a crazy “mind blowing” thing to wrap my head around. There is so much more research that could be done with the brain in the future, there are always new things to learn, as long as we are awake for them!
