According to the Centers for Disease Control and Prevention (CDC), over a third of US adults report getting less than the recommended amount of sleep. The same is true of children, and the number of teens is even higher: three-quarters of teens report not sleeping enough.
Per the CDC, sleep is a critical component of overall health, and insufficient sleep is linked to obesity, depression, type 2 diabetes, and heart disease. Poor sleep can also cause car crashes — the CDC estimates that more than 6,000 fatal crashes a year involve a drowsy driver.
