kékfényhatás
The kékfényhatás, or blue light effect, refers to the impact of blue light, a high-energy portion of the visible light spectrum, on biological systems. Primarily, it is associated with its influence on the human circadian rhythm, the body's natural sleep-wake cycle. Exposure to blue light, particularly in the evening, can suppress the production of melatonin, a hormone that signals to the body that it is time to sleep. This suppression can lead to difficulties in falling asleep and a disruption of sleep quality.
Sources of blue light are varied. Natural sources include sunlight, which is crucial for regulating our circadian
Beyond sleep, research is exploring other potential effects of blue light. Some studies suggest possible links
