Getting out of bed is no longer difficult! Blue LED lights can help people eliminate "morning sleep"



The results of the Korean research team show that proper lighting helps people to eliminate drowsiness in the morning. Maybe you will never get up again in the morning.


The Korea Advanced Institute of Science and Technology (KAIST) proposes that blue-enriched LED light can effectively improve the morning waking. This research has become a further support for the development of human lighting and provides the basis for a major change in the lighting strategy of the future.


A study of the 2017 Nobel Prize revealed the molecular mechanisms that control circadian rhythms. At the beginning of the 21st century, scientists discovered a new "third" kind of photoreceptor cells in the human retina and further studied the relationship between light and physiological effects.


The third type of photoreceptor cells regulate a variety of biological and behavioral processes such as melatonin, cortisol secretion, alertness, and functional magnetic resonance imaging (fMRI). Hyeon-Jeong Suk and Kyungah Choi, experts from KAIST Industrial Design, suggested that the effects of blue light on physiological responses can positively regulate melatonin levels. They carried out experiments and used different shades of morning light to illuminate for 1 hour to study whether different morning light had different effects on people's physiological responses and subjective responses. The results show that blue-enriched white light can significantly reduce melatonin levels compared to warm white light.

Choi experts added that when they studied all the psychological and physiological effects of light, they found that the role of light is much more than that. He believes that human lighting can be applied to various places such as residential areas, learning environments and work environments. The quality of life of people.

It is reported that the results of this study were published in the Journal of Scientific Reports on January 23, 2019.
