不同颜色的光强度的变化可以改变许多生理参数和状况，如褪黑激素、警觉性、体温、心率 (HR) 和心率变异性 (HRV)。这项试点研究的目的是调查红光 (631 nm) 和蓝光 (456 nm)（照度均为 140 lux）照射后的急性体温、HR、HRV 和精神状态反应。格拉茨医科大学使用新型彩色光板对七名健康志愿者（5 名女性，2 名男性；平均年龄 +/- SD 34.1 +/- 11.9 岁）进行了调查。仅在 10 分钟蓝光刺激后，鼻温 (P = 0.046)、HR (P < 0.05) 和总 HRV (P = 0.029) 才显着下降，与情绪状态的显着改变相关（压力水平评分，P = 0.006）。然而，对同一个人的红光刺激并没有对这些参数产生相同的影响。蓝光作为环境刺激对人体健康的影响尚未详细阐明，需要进一步研究。
Changes of light intensity of different colors can shift many physiological parameters and conditions likemelatonin, alertness, body temperature, heart rate (HR), and heart rate variability (HRV). The aim of this pilot study was to investigate acute temperature, HR, HRV, and state of mind reactivities after illuminationwith red (631 nm) and blue (456 nm) light (illuminance 140 lux for both). Seven healthy volunteers (5 females, 2 males; mean age +/- SD 34.1 +/- 11.9 years) were investigated at the Medical University of Graz, using new color light panels. Significant decreases were found only after 10 min blue light stimulation in nose temperature (P = 0.046), HR (P < 0.05), and total HRV (P = 0.029), in association with a significant alteration of the emotional state (stress level score, P = 0.006). However, red light stimulation of the same persons did not induce the same effects in these parameters. The effect of blue light as environmental stimulation on human health is not clarified in detail and needs further investigations.
