SLEEP DEPRIVATION ARTICLES


The UK Healthcare Good Samaritan Sleep Center in Lexington, Kentucky was in charge of this experiment. The students were living in Kansas. In this experiment, a county started their schools an hour later. This hour delay is believed to cause less car accidents. Instead of starting at 7:30 and 8:00 a.m., schools started at 8:30 and 9:00. This county used to have the highest crash rate. In the two year experiment, crash rates dropped 16.5%, opposed to in the rest of the state where it increased 7.8%. In my opinion, sleep is very crucial to living a healthy life. The lower crash rate is just proof to back up this statement. All schools should start later.

Judith A. Owens, M.D., M.P.H., of the Hasbro Children's Hospital, Providence, and colleagues, studied 201 students in grades 9 through 12 attending an independent high school in Rhode Island. They delayed the start time from 8:00 to 8:30. They saw that with this half hour delay, students were happier and more willing to participate. There was a decrease in students going to the doctor’s with fatigue-related symptoms. Students were more alert. In my opinion, sleep is very essential to a healthier, happier life. This survey proves this theory.

The study was supported by the National Space Biomedical Research Institute, the National Institutes of Health, the Institute for Translational Medicine and Therapeutics and the National Center for Research Resources. In this experiment, researchers took 92 healthy adults without the gene variant and 37 healthy adults who had the gene variant (DQB1*0602 gene) but didn’t have any sleep disorders. The first two nights, the participants slept 10 hours. The next five nights, the participants slept about 4 hours. The researchers found that, even on the first two nights, the people with the gene were more fatigued than those without the gene. Those with the gene variant spent less time in deep sleep. The two groups had the same results when they took memory and attention tests. There was also no difference in their ability to sleep during the day. In my opinion, this shows that people with this gene will have more fatigue, but there they won’t have any further problems.
