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

研究了光照强度、光照颜色和光照方式等对生理反应的影响。还研究了防止夜间工作者光诱导褪黑激素抑制的对策。结果表明：1）鼻侧视网膜的瞳孔对光反射明显大于颞侧视网膜，但褪黑素抑制作用差异不显著。2)瞳孔对光反射和总血红蛋白浓度的增加，暴露于蓝色单色光显着大于暴露于红光。3)戴红色遮阳帽或在夜间工作时小睡是防止夜间工作者光诱导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.
