The results of research by Korean scientists will in the future be used in the field of strategy formation
Much of the research has been devoted todebunking circadian rhythms, for which Jeffrey S. Hall, Michael Rosbash, and Michael W. Young were awarded the 2017 Nobel Prize in Physiology or Medicine for their discovery of mechanisms. In particular, Korean scientists investigated the relationship between light and its physiological effects, which began to be explored with the discovery of a new, third type of photoreceptor in the human retina. Rods and cones regulate visual effects, while a third type, light-sensitive retinal ganglion cells, regulate a wide variety of biological and behavioral processes, including the secretion of melatonin and cortisol, as well as sleepiness.
Initial studies of light sourcesshowed that blue monochromatic light sources are effective in stimulating physiological responses. Moreover, the study focused on the negative effects of blue light; for example, when people are exposed to blue light at night, they have difficulty achieving deep sleep because the light inhibits the secretion of melatonin.
However, Professor Hyun Jung Sook, Prof.Kyunga Choi from the Department of Industrial Design and their team argue that the effects of blue-enriched morning light on physiological responses are time dependent and that it has a positive effect on melatonin levels and sleepiness, mood and visual comfort compared to warm white light.
Professor Suk notes: “Light takes a large part of our lives because we spend most of our time indoors. Light is one of the most powerful tools that influences changes in our perception and perception of our environment. ”
