Everyone has trouble sleeping occasionally, but people with insomnia have trouble sleeping for more than three weeks without improvement(Sharon L. Schutte-Rodin, 2006). Their sleep problems also interfere with their ability to function during the day.
Studies have also shown a correlation between sleep problems and levels of stress.
Not getting enough sleep can increase a person’s stress. Studies have shown that people who sleep less have higher amounts of cortisol — a hormone that is related to stress, depression and cardiovascular disease — in their bodies. With a good night’s rest, the body regulates the levels of the hormone that can cause stress, according to the Newsweek article.
But another study shows that stress is the main factor in students’ poor sleep quality. The study, published in the Journal of Adolescent Health, found that stress from school and life keeps 68 percent of students awake. Of those students, 20 percent couldn’t sleep at least once a week due to stress.
“Students underestimate the importance of sleep in their daily lives. They forgo sleep during periods of stress, not realizing that they are sabotaging their physical and mental health" (Sharon L. Schutte-Rodin, 2006).
