Light exposure research focuses on the effects of natural and artificial light on human health and well-being. This area of study often investigates how light exposure can influence circadian rhythms, sleep patterns, mood, cognition, and overall physiological processes. Researchers examine the impact of different types of light, such as sunlight, blue light, and red light, on various aspects of human biology and health. Additionally, studies in this field may explore the potential benefits of light therapy for conditions like seasonal affective disorder, insomnia, and depression.
