The Dangers Of Too Much Sleep

New research finds that both insufficient and excessive sleep may raise the risk of cardiovascular problems and premature death.

The Centers for Disease Control and Prevention (CDC) report that a third of the United States population does not get enough sleep.

The CDC also warn that sleep deprivation raises the risk of various chronic conditions such as diabetes, cardiovascular disease, obesity, and depression.

But, according to new research appearing in the European Heart Journal, sleeping too much may affect health just as negatively as sleeping too little.

Chuangshi Wang, a doctoral candidate at McMaster University in Ontario in Canada, and Peking Union Medical College at the Chinese Academy of Medical Sciences in China, is the lead author of the new paper.

The health consequences of too much sleep

Wang and colleagues examined the sleeping habits of more than 116,000 people aged between 35 and 70 years who had enrolled in the Prospective Urban Rural Epidemiology (PURE) study.

In their analysis, the researchers also included information about the participants’ socioeconomic status, lifestyle habits, physical activity, diet, use of various medications, and family history of chronic conditions.

Overall, 4,381 people died and 4,365 people had a heart attack or stroke during the 8-year follow-up period of the PURE study.

The analysis by Wang and her team revealed that people who regularly slept more than the recommended 6–8 hours a night were more likely to die prematurely or develop cardiovascular disease.

More specifically, the risk of premature death or cardiovascular conditions was 5 percent higher for people who slept 8–9 hours than for people who slept the recommended amount.
