Our overall health is affected by our quality of sleep. Studies show that persistent lack of quality sleep can increase the risk of conditions such as heart disease, high blood pressure, diabetes, obesity, and even certain types of cancer. The need for sleep crosses all age groups. Even teenagers need at least 7 hours of quality sleep. “In one of the largest and most comprehensive studies of its kind, scientists tracked the sleep and daytime activity of 829 adolescents for 7-10 days. They evaluated the quantity and quality of sleep, as well as factors related to cardiovascular health—including blood pressure, cholesterol levels, and abdominal fat distribution. The researchers found that the teens who slept less than 7 hours a night (nearly a third of the participants) tended to have more body fat, elevated blood pressure, and less healthy cholesterol levels.”
