OLED lighting can have a positive effect on your sleep and may even help you lose weight

Researchers at the University of Tsukuba in Japan, in collaboration with Yamagata University, have compared the effects of LED and OLED lighting on physiological processes during sleep.

The researchers showed that OLED light has a lower negative impact on energy metabolism compared to LED light.


White LEDs emit large amounts of blue light, which has been linked to many negative health effects, including metabolic health. In contrast, OLEDs emit white light, which contains less blue light.


The study proved that while this had no effect on sleep architecture, it significantly reduced core body temperature and energy expenditure during sleep. In addition, after OLED exposure, fat burning during sleep was significantly higher than after exposure to LED light.

The results suggest that light exposure to OLED light sources before bedtime, together with other physiological effects, can positively influence weight loss.


OLED lighting thus has an effect similar to that of subdued light.


Exposure to blue light has historically been linked to numerous health problems - and one of the advantages of OLED panels has always been the lower emission of blue light compared to LED-based technologies. This is true for both OLED lighting and displays.
