Turn Off the Blue Light!

Researchers from University of Tsukuba in collaboration with Yamagata University scientists find that exposure to light with less blue before sleep is better for energy metabolism

Tsukuba, Japan—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 June 2021 in Scientific Reports, researchers from University of Tsukuba compared the effects of light-emitting diodes (LEDs), which have been widely adopted for their energy-saving properties, with organic light-emitting diodes (OLEDs) on physical processes that occur during sleep.
