Blue Light Exposure and Energy Metabolism
Razi Berry Extended exposure to light during nighttime can have negative consequences for human health. But now, researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep. In a study published in Scientific Reports, researchers from University of Tsukuba compared the effects of light-emitting diodes (LEDs), which […]
