For the study, 20 healthy adults 18 to 40 years were randomised into dark-dark or dark-light groups and run in parallel for a three day and two-night stay. Participants had eight hours of sleep opportunity each night starting at habitual bed-time determined from one week of actigraphy with a sleep diary. The results showed that a single night of light exposure during sleep acutely impacts measures of insulin resistance. Insulin resistance is the diminished ability of cells to respond to insulin action transporting glucose out of the bloodstream and precedes the development of type-2 diabetes.
