Sleep is an essential body function, so the effects of sleep deprivation (too little sleep) or sleep deficiency (too little or poor-quality sleep) can significantly affect one’s health. Unfortunately, inadequate sleep is a common issue, with one out of three adults in the US reporting not getting enough sleep.
As a result, the health consequences of sleep deficiency and deprivation are serious. Poor sleep is linked to increased rates of heart disease, diabetes, obesity, depression, and high blood pressure. Injury and fatality is also a concern, with drowsy driving causing an estimated 6,000 fatal motor vehicle accidents a year, per the CDC. In the elderly, sleep deficiency can lead to falls and fractures.
