Color influences on human beings evaluated by nasal skin temperature

Abstract

The relationship between physiological and psychological indices was investigated when the color of the environment (red, blue, or yellow) was changed. An evaluation indexA visual analogue scale (VAS) was used as the psychological index, while nasal skin temperature was used as the physiological index. Figure 1 shows an example of a VAS.Abstract Since colors affect human beings both physiologically and mentally, various studies have been conducted about the infl uences of color. Most of the studies have been focused on the psychological aspects. In this study, we investigated the infl uences of color physiologically by the use of infrared thermography. With this technique, the subjects wear no devices, and objective values are expected to be obtained to evaluate the infl uences of color. Nasal skin temperatures were measured by infrared thermography under yellow, red, and blue illuminations. A signifi cant temperature change was observed under red illumination.

Enhancement of Autonomic Stress Response and Reduction of Subjective Stress by Lavender Inhalation During a Short-term Calculation Task

“…Therefore, the skin temperature at the site of interest can be measured as an index of sympathetic nervous system activity [9,10]. In particular, the temperature at the tip of the nose has been used as an objective measure of psychological stress [11][12][13][14][15]. To our knowledge, few olfactory studies have assessed skin temperature to estimate peripheral autonomic nervous system activity.…”

Evaluation of the effects of food intake on task engagement based on psychophysiological states

“…Skin temperatures are affected by ambient conditions. By subtracting the skin temperature of the forehead from the NST, the ambient influences can be reduced [27]. For this study, the NST was adjusted by subtracting the mean of the right forehead skin temperature and the left forehead skin temperature.…”
