After 50 years of researching, scientists still don’t have an answer as to why we require sleep. The closest thing we have to a reason is what one scientist said.
As far as I know, the only reason we need to sleep that is really, really solid is because we get sleepy.
One-third of our life is spent sleeping from the time of birth. There is no sure reason as to why, even after several decades of research.
A 29-year-old woman from St. Louis is an Army sergeant named Cheryl Dinges. She has a job to do, and that is to train soldiers in physical combat. Brazilian jujitsu is what her specialty is. This job deals with quite a bit of fighting. But, Cheryl is facing a fight that is even more difficult. Her family carries a gene for what is called fatal familial insomnia. Not being able to sleep is the main symptom of this disease. It is a gradual decrease in sleep. First, the usual daytime nap that you are used to becomes nonexistent. Next, you will find that you cannot sleep a full night through. Then, you will not be able to get any sleep. When the victim of this disease is in his or her 50’s is when the disease begins to kick in. It will normally last for a year but, it always ends with death. Hence, the name of the disease. Dinges has refused to be tested to see if she carries the gene. She said,
I was afraid that if I knew that this was something I had, I would not try as hard in life. I would allow myself to give up.
