AB - As a cooling device for cooling the human body, the cooling garment has been used in many fields. This study was guided by the theory of traditional Chinese medi¬cine, an acupoints-meridians cooling vest (AMCV) system was designed to cold and stimulate the acupoints and meridians of the human body. Three healthy male subjects were recruited to participate in the test, with AMCV or without AMCV (CON), in a high temperature environment (37 ±1℃, 46 ±3% RH) to simulate standing on duty for 50 minutes. The results showed that the skin temperature, Tskin, with AMCV was lower than that with CON (p < 0.05). The average Tskin with AMCV decreased by 0.45 ℃ more than that with CON (p < 0.05). The average tympanic temperature, Tty, with AMCV was lower than that with CON (p < 0.05). Howev¬er, the average Tty with AMCV decreased by 0.05℃ more than that with CON (p < 0.05). The heart rate with AMCV was significantly lower than that with CON (p < 0.05). The average thermal sensation and thermal comfort with AMCV were better than those with CON in the corresponding period (p < 0.05). The results indicated that AMCV could improve thermal comfort and reduce the heat strain of the human body in a high temperature environment.
