Effects of hot or cold impressions to thermoregulation and its individual variation

本研究的目的是明确实际的体温调节反应是否受到视觉刺激给人的冷/热印象的影响。结果，在常温环境下，当被试被呈现热图像或冷图像时，总外周阻力和心率变异性发生了显著变化。换句话说，当暴露于热图像条件下时，血管会像夏天那样扩张。当暴露于冷图像条件下时，观察到心率降低和血管收缩等反应。此外，在实际冷环境的情况下，热图像条件下的核心温度显著低于冷图像时的核心温度。另一方面，印象的贡献似乎存在个体差异，因为有些参与者没有通过图像效应改变体温。

The aim of this study is to clear whether the actual thermoregulatory reaction was affected by visual stimulation gave a cold/hot impression.As a result, total peripheral resistance and heart rate variability has changed significantly in the normal temperature environment when participants were presented a hot image or a cold image.In other words, when exposed to the hot image conditions, blood vessels tended to expand as in the actual summer heat. When exposed to the cool image conditions, reactions of such heart rate decrease and blood vessel contraction was observed.In addition, in the case of actual cold environment, core temperature in hot image conditions was significantly lower than when presented cold image.On the other hand, it would appear that there were individual differences in the contribution of impressions, because some participants did not change body temperature by the image effect.
