LED lighting orange light helps sleep, blue light can inhibit the body's melanin

LED lighting orange light helps sleep. Blue light can inhibit melanin in the human body. According to media reports, devices such as smartphones and tablet computers usually use LED lighting. The blue light emitted by them may inhibit the body's production of melatonin, which helps people fall asleep. The effect of orange light may be even more opposite to that of blue light: the subject wore orange glasses every night during a week and reported that they became 'significantly more sleepy.' The Journal of Adolescent Health previously published a study from Switzerland. The boys who participated in the experiment were monitored in the laboratory. Like ordinary teenagers, they watched an electronic screen for several hours before going to bed every night. This study involving a teenage boy showed that the subjects wore orange glasses (also known as blue light blocking glasses) every night during a week to prevent the melatonin inhibitory effect, and they were 'significantly better than when they were wearing clear glasses.' Sleepy'.   The blue part of the spectrum in LED lighting can inhibit the body's production of melatonin, and melatonin can help people fall asleep**.   In addition, research has pointed out that older people may be less affected by blue light. But for most people, Blu-ray is still a problem. A previous study involving adults up to ages found that the sleep quality of those wearing amber glasses three hours before going to bed was much better than that of a control group wearing yellow contact lenses that only block ultraviolet rays. Devices such as smartphones and tablet computers usually use light-emitting diodes, or LED lighting, which often emit more blue light than incandescent products. Debra Skene, a professor of neurology at the University of Southampton in the United Kingdom, pointed out that TVs with LED backlights are another source of blue light, but their viewing distance is generally smaller than that of small screens such as mobile phones. Much far, the impact on the human body should be relatively small. The study also pointed out that LEDs are becoming more and more popular in indoor lighting, but if it is only used at night, 'warm white' light bulbs with less blue light are actually a better choice than 'cool white' light sources.  'Conceptually, anything that reduces blue light exposure at night will help,' said Christopher Colwell, a neuroscientist at the University of California, Los Angeles. 'I know some gamers admire orange goggles.'   But orange glasses are not a panacea, Dr. Skane said. 'Blocking blue light does not solve all problems.' In addition to color, the intensity of light also affects sleep, she said, and not all brands of orange glasses have undergone enough independent tests to confirm that they are indeed capable of assisting sleep.  Experts say that in the daytime, blue light exposure is still very good. *A good light source is sunlight, which contains many different wavelengths of light. At present, CSA is being accepted by dozens of member units of the National Semiconductor Lighting Engineering Ru0026D and Industry Alliance. It is believed that it will be recognized by more and more companies in the near future, and it will certainly play a huge role in promoting the Ru0026D and industrial development of LED lighting products. . The number of samples is at least one. The more samples, the higher the confidence of the test results.
