Sleeping less doubles the risk of heart attack in men also it increases the risk of having stroke up to four folds, warns a new study. According to researchers, men with sleeping disorders who sleep less than 7 hours in night ups the risk of myocardial infarction by 2 to 2.6 times while stroke risk was 1.5 times to 4 times higher when compared to men who had proper sleep.
For the study, researchers included samples of 657 men aged between 25 and 64 in Novosibirsk, Russia. All the men had no history of heart attack, stroke or diabetes. Scientists evaluated sleep quality of all the participants using ‘Jenkins Sleep Scale’ from 1994 to 2008.
After analyzing the data study authors noted that during the period of 14 years nearly two-third of the participants who had heart attack were also patients of sleep disorders.
“Sleeping disorders were associated with greatly increased incidences of both heart attack and stroke,” said Valery Gafarov, professor of cardiology at the Russian Academy of Medical Sciences in Novosibirsk. “Sleep is not a trivial issue. In our study it was associated with double the risk of a heart attack and up to four times the risk of stroke. Poor sleep should be considered a modifiable risk factor for cardiovascular disease along with smoking, lack of exercise and poor diet,” said Gafarov.
Gafarov also found that social connection was interlinked with the rate of heart attack and stroke among men with sleeping disorders. Gafarov warned that poor sleep is similar to smoking cigarette, eating poor diet and lack of exercise.
While explaining what amount of sleep a person should take for a healthy life he said that for most people 7-8 hours of sleep is enough, and sleeping less than that is a call for danger.
In the previous study by scientists at Warwick University it was found that 30 percent more long sleepers and 12 percent more short sleepers died early than the moderate sleepers within the same period of time.
The study was presented at a meeting of the Council on Cardiovascular Nursing and Allied Professions (CCNAP) of the European Society of Cardiology (ESC) in Croatia.
