Light exposure during sleep impairs cardiometabolic function

What this work gives Aellic

20 healthy adults, randomised parallel groups (n = 10 each): one night of sleep under 100 lx overhead room light, compared with less than 3 lx, raised night-time heart rate, lowered HRV and increased next-morning insulin resistance. A single night in a small sample, testing room light rather than a small standby LED.
