Even if you sleep normally, your body health and neurological condition will deteriorate. If you ever think you are not sleeping, you can imagine how difficult life can be. A 19-year-old teenager named Randy Gardner at a science fair in 1965, never sleeping for 11 days. According to the research done between 8-10 days people can live without harm. The only thing that is found on all these subjects is the lack of concentration and motivation. Long-lasting insomnia slows down perceptual capacity and mental activity.

In a study in the United States, rats were sleep deprived for two weeks. By examining the brains of the mice, they were awakened by various stimuli in their sleeping buds. 15 days of sleepless mice have lost their lives. So what was it that killed the rats directly? Experts explain this phenomenon as the body's bankruptcy, depending on the slowing of brain activities.

But the more interesting thing is Morvan Syndrome. People who have this disease never sleep. There are even people who have never slept for 50 years. Moreover, this disease, which can continue to normal life, is very rare. Patients with autonomic and nervous system involvement and endocrine dysfunction are unable to sleep. Moreover, there is no known therapy for morphea syndrome. With the cause of this disease, muscle twitches, pain, sweating often occur. Even if it is very rare, there are people who live in this world. It is thought to be due to an antibody produced by nerve cells.
