Physio用sychological bra in responses to light and adaptation to health risk

考察了光照强度、光照颜色和光照方式对生理反应的影响。文中还探讨了防止夜间作业人员光致褪黑素抑制的对策。结果发现：1)光暴露于鼻侧视网膜的瞳孔光反射显著大于暴露于颞侧视网膜的光反射，但对褪黑素的抑制作用差异不显著。2)单色蓝光对瞳孔的光反射和总血红蛋白浓度的升高明显大于红光。3)戴红帽或在夜间工作时午睡是预防夜间工作人员光所致褪黑素抑制的有效对策。

The effects of light intensity, color, and way of light exposure on physiological responses were examined. The countermeasures to prevent lightinduced melatonin suppression in night workers were also examined. We found the following results : 1) The pupillary light reflex by light exposure to nasal retina was significantly larger than that to temporal retina, but difference in melatonin suppression was not significant. 2) The pupillary light reflex and increase in total hemoglobin concentration by exposure to blue monochromatic light was significantly larger than those by exposure to red light. 3) Wearing a red-visor cap or taking a nap during night work were useful countermeasure to prevent lightinduced melatonin suppression in night workers.
