Summary
This study looked at whether being exposed to artificial light at night, on top of not getting enough sleep, harms how the body handles sugar. 14 healthy adults spent over a month in a lab to compare sleep restriction with and without extra light. The goal was to understand how light and sleep loss together affect insulin and blood sugar control.
