Just ask any parent or teacher, most of today’s teens and pre-teens don’t seem to get enough sleep. And what sleep they do get is often poor quality—no great surprise, given that smartphones and other electronic devices are usually never far from their reach. Now, an NIH-funded team has uncovered the strongest evidence yet that this lack of quality sleep may be setting our kids up for some serious health issues later in life.
The team’s study of more than 800 adolescents, ages 11 through 13, confirmed that many are getting an insufficient amount of undisturbed, restful sleep each night. While earlier studies had found a link between sleep duration and obesity , the new work shows that a wide range of other cardiovascular risk factors are affected by both too little sleep and poor sleep quality . When compared to well-rested kids, sleep-deprived youth were found to have higher blood pressure, bigger waistlines, and lower levels of high density lipoprotein (HDL) cholesterol, which is associated with lower risk of cardiovascular disease.
