Study: Less than 6 hours of sleep could be deadly for some
Those with high blood pressure, Type-2 diabetes, heart disease or stroke could be at high risk of cancer and early death when sleeping less than six hours a day, says a study. "Our study suggests that achieving normal sleep may be protective for some people with these health conditions and risks," said lead study author Julio Fernandez-Mendoza from Penn State Health Milton S. Hershey Medical Center in Hershey in Pennsylvania, US.
"However, further research is needed to examine whether improving and increasing sleep through medical or behavioural therapies can reduce risk of early death," Fernandez-Mendoza said. For the study, the researchers analysed the data of more than 1,600 adults who were categorised into two groups as having stage 2 high blood pressure or Type-2 diabetes and having heart disease or stroke.
Participants were studied in the sleep laboratory for one night and then researchers tracked their cause of death up to the end of 2016. The researchers found that of the 512 people who passed away, one-third died of heart disease or stroke and one-fourth died due to cancer.
