A study carried out by a team of researchers at the Keele University, Newcastle United Kingdom revealed people who regularly sleep for more than 8 hours a night stands a greater risk of developing cardiovascular diseases and death that those that sleep for seven hours or less.
News-medical.net revealed sleeping for up to 10 hours was associated with about 30 percent risk of dying compared with seven hours or less.
Chung Shing Kwok, the lead author of the research which was published in the Journal of the American Heart Association studied the relationship between self-reported sleep duration and quality, cardiovascular outcomes and death rate across 74 studies.
“This research began because we were interested in learning if it was more harmful to sleep below or beyond the recommended sleep duration of seven to eight hours. We further wanted to know how incremental deviation from recommended sleep duration altered risk of mortality and cardiovascular risk,” Kwok said.
During the course of the study, it was also discovered sleeping for 10 hours increases the risk of death from stroke and cardiovascular disease by 56 percent and 49 percent respectively.
The lead researchers suggest doctors make inquiries about duration of sleep when talking to patients as this research finding shows too much sleep is unhealthy for individuals.
Kwok concluded that “The important message was that abnormal sleep is a marker of elevated cardiovascular risk and greater consideration should be given in exploring both duration and sleep quality during patient consultations.”
