Everyone benefits when we get enough sleep to run our bodies and our brains.

A healthy sleeping schedule is important for the health of anyone. Many people are subject to sleep deprivation or deficiency. Sleep is involved in healing and repairing the heart and blood vessels. Continued sleep deficiency can be related to an increased risk of heart, kidney disease, high blood pressure, diabetes, stroke, and depression.

Sleep deprivation occurs when people are not sleeping enough, when they sleep at the wrong times of the day, when they do not sleep well, or when they have sleeping disorders that causes poor quality sleep. Sleep deficiency can lead to physical and mental problems, injuries, loss of productivity, and a greater risk of death.

Sleep helps the brain function in healthy ways. Studies show that sleep improves learning and that sleep deficiency alters parts of the brain responsible for decision making, problem solving, controlling emotions and behavior, and coping with change. Children and teenagers who are sleep deficient may feel impulsive, have mood swings, experience sadness or depression, or lack motivation.

Sleep supports the developing body, too. Deep sleep triggers the hormone that promotes normal growth in children and teens, boosts muscle mass and repairs cells and tissues. Sleep even plays a role in puberty and fertility.

Anyone can be affected by sleep deprivation, so students should evaluate their own sleep as well as keep watch for any peers who may be expressing signs of fatigue or tiredness.
