摘要
为研究高温环境下人体年龄对热生理与行为能力的影响,招募3个年龄段(20、30、40岁组)的男性,在温度40℃、相对湿度40%的高温环境下,采集受试者的主、客观生理反应和行为能力指标。结果表明:20、30岁组受试者的热耐受性优于40岁组,表现出更好的散热能力和恢复能力;各年龄段热感觉、热舒适性主观评价无显著差异(p>0.05),中年男性高温环境下比年轻男子出汗晚且少,40岁组的皮肤湿度、疲劳程度最低(p<0.05);受试者不同阶段的行为能力除20岁组视觉保留外均无显著差异,即核心温度在38.5℃以内对人体的行为能力没有显著影响。
In order to investigate the effect of human age on thermo physiology and behavior ability in a high temperature,three groups of male subjects(20-year-old,30-year-old,and 40-year-old)were recruited,and the subjective and objective physiological responses and behavioral ability indexes were collected under the condition of temperature 40℃and relative humidity 40%.The results show that the heat tolerance of 20-year-old and 30-year-old subjects is better than that of 40-year-old group,showing better heat dissipation and recovery ability.There is no significant difference in thermal sensation and thermal comfort among different age groups(p>0.05).Middle aged men sweat later and less in high temperature environment than young men,and skin humidity and fatigue degree in 40-year-old group are the lowest(p<0.05).There is no significant difference in the behavioral ability of subjects at different stages except visual retention of the 20-year-old group;that is,the core temperature within 38.5℃has no significant effect on human behavioral ability.
