The results of research by Korean scientists in the future will find application in the field of strategy formation.
Much of the research was devoted toexposing circadian rhythms, for the discovery of the mechanisms of which in 2017, Jeffrey S. Hall, Michael Rosbach, and Michael V. Young were awarded the Nobel Prize in Physiology and Medicine. In particular, Korean scientists investigated the relationship between light and its physiological effects, which began to be investigated since the discovery of a new, third type of photoreceptors in the human retina. Rods and cones regulate visual effects, while a third type, photosensitive retinal ganglion cells, regulates a wide variety of biological and behavioral processes, including melatonin and cortisol secretion, as well as drowsiness.
Initial studies of light sourcesshowed that blue monochromatic light sources are effective for stimulating physiological reactions. Moreover, the study focused on the negative effects of blue light; for example, when people are exposed to blue light at night, it is difficult for them to achieve deep sleep, because light inhibits melatonin secretion.
However, Professor Hyun Jung Suk, ProfessorKunga Choi from the Industrial Design Department and their team argue that the effect of blue enriched morning light on physiological responses depends on time and that it has a positive effect on melatonin level and drowsiness, 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. ”
