Strangely, scientists still haven’t figured out why sleep is so crucial for our survival. But they do know that not getting enough wrecks our health. Now, a new study out of Northwestern University reveals that having a light on while sleeping can raise your risk of diabetes. 

For the study—published in the journal, Sleepresearchers recruited 20 healthy adult volunteers (ages 18 to 40). The volunteers spent two nights and three days at the lab: The first night, they slept in pitch black darkness; the second night, half of them slept in the dark again while the other half slept in a room with a bright overhead light on. While the volunteers slept, the researchers tracked the volunteers’ vital signs, brain wave activity, and leg and eye movements; they also took hourly blood samples to measure melatonin—a vital hormone that helps control your internal clock (circadian rhythm) and typically rises during sleep. In the morning, the researchers conducted glucose tolerance tests on the volunteers.

When insulin can’t do its job, the body struggles to process sugar. “Our preliminary findings show that a single night of light exposure during sleep acutely impacts measures of insulin resistance,” said lead author Ivy Cheung Mason, PhD, a postdoctoral fellow at Northwestern’s Feinberg School of Medicine (at the time of the study), in a press release.

Previous research has linked poor sleep to a higher risk of depression, breast cancer, and prostate cancer.
