TOKYO (Dispatches) --- Researchers from Japan have identified a new type of light with reduced consequences for physiological changes during sleep.
In a study researchers 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.
Polychromatic white LEDs emit a large amount of blue light, which has been linked with many negative health effects, including metabolic health. In contrast, OLEDs emit polychromatic white light that contains less blue light. However, the impact of LED and OLED exposure at night has not been compared in terms of changes in energy metabolism during sleep, something the researchers at University of Tsukuba aimed to address.
