It’s common knowledge that everyone should get at least eight hours of sleep. It can be most difficult on school nights when a student or teacher must stay up late working on assignments and wake up before dawn. Some effects of sleep deprivation are mood swings, depletion of cognitive response, premature aging, overeating, and can even increase the risk of death.

Mood Swings

Naturally, people are more irritable when they’re tired. Going many nights with little to no sleep can lead to anxiety, depression, or bipolar disorder.

Depletion of Cognitive Responses

Sleep loss can impair a person’s alertness, learning ability, memory, and problem solving capabilities. In a school environment, students and teachers need maximum brain function in order to correctly operate within the classroom.

Premature Aging

People as young as 14 can experience signs of age such as wrinkles, dark circles, and hair loss due to lack of sleep. When someone neglects the need to rest, their body produces cortisol, a hormone for stress. Cortisol breaks down the proteins that keep skin smooth and stretchy.


Sleep loss is related to an increase in hunger and weight gain. People who sleep less than 7 to 8 hours are more likely to gain pounds than people who sleep longer.

Increased Risk of Death

When someone doesn’t sleep enough, they run a greater chance of having a stroke, heart attack, or high blood pressure. People who cut back their amount of sleep nearly double the risk of death.
