This is how many hours of sleep you need to avoid metabolic syndrome
Too much and too little sleep can raise your risk of heart disease and diabetes, according to new research. So what’s the perfect amount?
Researchers have determined yet another reason we should be aiming for eight hours of sleep a night with a new study concluding that those of us who get too little or too much sleep could be at risk of developing a variety of health conditions.
The study, recently published in the journal BMC Public Health, found that people who get less than six hours of sleep a night more likely to develop metabolic syndrome. Interestingly those who managed more than 10 hours of sleep were also at risk.
Metabolic syndrome is actually a series of conditions including high blood sugar and cholesterol levels and increased blood pressure. Sufferers also typically gain excess fat around the waist area.
Researchers from Seoul National University College of Medicine examined data from over 133 000 Korean men and women, analysing the effect that sleep had on their ability to develop the condition.
Those individuals who either slept too much or too little showed elevated blood sugar, cholesterol and blood pressure and also had additional fat around their waists.
“This is the largest study examining a dose-response association between sleep duration and metabolic syndrome and its components separately for men and women,” said Claire E. Kim, lead author of the study.
“We observed a potential gender difference between sleep duration and metabolic syndrome, with an association between metabolic syndrome and long sleep in women and metabolic syndrome and short sleep in men.”
Although the study authors noted that their research was only observational, meaning that they were unable to draw iron-clad conclusions, it may be best to aim for eight hours of shut-eye just in case.
