Less than 6 hours’ sleep daily linked with higher risk of type 2 diabetes

Embargoed until: Publicly released:

Are you a short sleeper? You could be at higher risk of type 2 diabetes even if you’re a healthy eater, according to international researchers. The team looked at data from 247,867 adults in the UK, and found that people sleeping less than six hours daily had a notably higher risk of developing type 2 diabetes compared to those who slept seven or eight hours. The authors also found that this increased risk was seen even in those with healthier diets, despite this usually reducing type 2 diabetes risk. While this kind of study can’t show cause and effect, the findings show the importance of sleeping well and eating well, especially for those at high risk of developing diabetes, according to the team.
