Abstract

本研究は色光が手掌冷水刺激における生理的・心理的反応に与える影響を検討した.実験は,20代女子大学生10人を被験者として,白,青,赤それぞれの色光環境で被験者の左手掌を15℃の水に3分間つけさせて冷水刺激を与えた.実験中は被験者の皮膚温,皮膚血流,血圧,心拍などの生理的指標を継続的に計測した.また,3色の色光に対する印象,実験時の気分,温度感覚,寒冷による不快感および体温回復の主観的な感覚などの心理的指標をSD法およびPOMSにより計測した.生理的指標の測定結果から,青の色光環境において,冷水刺激により低下した皮膚温の回復がより速く,冷却側の皮膚血管の収縮が軽減され,皮膚血流量の回復が早いことが明らかとなった.心理的指標の測定結果から,3色の色光の軽快感や寒暖感における印象に差が見られた.また,色光により,実験中の気分および温度感覚が異なることが示された.具体的には,冷たい色と評価された青は寒冷による不快感を増強し,心理的覚醒を喚起する一方,暖かい色と評価された赤は寒冷による心理的不快感を軽減した.本研究で青の色光に特徴として見られた心理的覚醒は,皮膚交感神経活動の低下に関連すると考える.本研究の結果は色光は認知過程を通して,気分と温度感覚を変化させ,自律性体温調節反応にも影響を及ぼすことを示唆した.

The purpose of this study was to examine the physiological and psychological responses to color lights during cold water immersion test. Ten female subjects aged between 20 to 30 years were asked to immerse their left hand in 15℃ water for 3 minutes respectively under white, blue and red color light. The subjects' skin temperature, skin blood flow, blood pressure and electrocardiogram were continuously measured. At the meantime, psychological questionnaires were conducted, focusing on subjects' impression of the color lights, mood, thermesthesia, cold discomfort, and subjective feelings of temperature recovery during the test. The physiological results indicate that under blue color light, reduced skin temperature under cold water immersion recovered relatively faster compared to other color lights. Skin blood flow also recovered faster under blue color light. The psychological results show difference in the impression among 3 color lights in terms of "pleasant" and "warm and cool". Meanwhile, subjects' mood and thermesthesia were different to each color lights. Specifically, blue color light, evaluated as cool color was considered increasing the discomfort of cold, thus leading to emotional arousal. On the other hand, red color light, evaluated as warm color was considered decreasing the discomfort of cold. In this study, as the characteristic of blue color light, emotional arousal was estimated associated with skin sympathetic nerve inhibition. This study may suggest color lights affect mood, thermesthesia and thermoregulation through cognitive process.
