Sleeping less than seven and a half hours per day may be associated with future risk of heart disease, according to a report in the November 10 issue of Archives of Internal Medicine, one of the JAMA/Archives journals. In addition, a combination of little sleep and overnight elevated blood pressure appears to be associated with an increased risk of the disease.
“Reflecting changing lifestyles, people are sleeping less in modern societies,” according to background information in the article. Getting adequate sleep is essential to preventing health conditions such as obesity and diabetes as well as several risk factors for cardiovascular disease including sleep-disordered breathing and night-time high blood pressure.

Humans spend about a third of our lives sleeping. Over the course of an average 70–year lifespan, that equates to about 205,000 hours.Sleep is vital in everyone’s life.
Why is it so important? Our health, happiness, and ability to succeed in life are strongly dependent on how well we meet the body’s need for rest and quality sleep. Sleep is a naturally occurring period in every 24-hour period of a human’s life, in fact. It’s during the sleep phase of our daily cycle that the body repairs itself, tests its systems, consolidates memory, purges itself of waste, and stockpiles energy for the day ahead.
