New findings explain the connection between melatonin and type 2 diabetes

(Lund University) A new experimental and clinical study from Lund University in Sweden shows that the sleep hormone melatonin impairs insulin secretion in people with a common gene variant. 'This could explain why the risk of type 2 diabetes is greater among, for instance, overnight workers or people with sleeping disorders,' says Professor Hindrik Mulder who is responsible for the study.
