A Rresearch conducted at the Faculty of Medicine at West Virginia have found that sleeping less than five hours a day have a two times larger risk of suffering from angina, coronary heart disease, heart attack or stroke.
But excessive sleep over seven hours a day also brings the same risks for heart health. A study revealed, those who sleeps nine hours or more a day are at risk of developing cardiovascular disease.
The research was led by Anoop Shankar by analyzing data of more than 30,000 adults collected in a national study in the United States in 2005.
The research was classified by age, gender, race, weight, activity, and lifestyle like cigarette and alcohol consumption. Groups of people with diabetes, high blood pressure, or depression were not included.
The age group which are most susceptible to heart disease are adults under 60 years old who slept less than five hours each night. Their risk of heart attack are three times greater than those who slept seven hours a day.
Researchers explained that a lack of sleep can cause disorders of glucose tolerance and reduce insulin sensitivity and high blood pressure. This conditions increases the risk of hardening of the arteries that leads to heart disease.
American Academy of Sleep Medicine recommends that adults are encouraged to sleep around seven to eight hours every night.Tagged with: angina, Cardiovascular Disease, Coronary Heart Disease, glucose tolerance, Heart Attack, Heart Health, insulin sensitivity, Lack Of Sleep, Naps, Risk Of Cardiovascular Disease, Risk Of Heart Attack, Sleep, stroke,
