Researchers from the University of Tsukuba in Japan compared the effects of inorganic light-emitting diode (LED) and organic light-emitting diode (OLED) lighting before sleep on the physiological processes in the human body during sleep. The researchers concluded that OLEDs have less impact on sleep and energy metabolism.

OLED lighting can improve sleep and even help reduce weight

The OLED spectrum contains less blue light than the LED spectrum. This does not affect the structure of sleep, but leads to a decrease in energy expenditure and body temperature. In addition, fat oxidation during sleep was significantly less after LED exposure compared to OLED. By the way, dim light works in a similar way.

The data obtained indicate that certain types of light exposure can affect the increase in body weight and other physiological changes. Perhaps choosing the type of light source used before bed in favor of OLED can have positive consequences.
