This study investigates the influence of alcohol on body core temperature during cold-water immersion in human volunteers. In this randomised, double-blind, placebo-controlled crossover trial, 8 healthy male volunteers were randomised to drink 1 litre of beverage containing 50 g alcohol or placebo before 20 degrees C cold-water immersion for 1 hour. Body core temperature was measured before cooling and after 1 hour of immersion with an infrared ear thermometer. After a 1-week interval subjects crossed to the other study branch. In the placebo test, mean temperature decreased after immersion by 0.66 degrees C; after the alcohol mean temperature decreased by 1.0 degrees C (mean difference 0.34, 95% CI 0.14-0.53, P = 0.002).
本研究调查了酒精对人体志愿者冷水浸泡期间体核温度的影响。在这项随机、双盲、安慰剂对照的交叉试验中,8名健康男性志愿者被随机分配在20摄氏度的冷水浸泡1小时前饮用1升含50克酒精的饮料或安慰剂。在降温前和浸泡1小时后,用红外耳温计测量体核温度。间隔1周后,受试者交叉至另一研究组。在安慰剂测试中,浸泡后平均温度下降了0.66摄氏度;饮用酒精后平均温度下降了1.0摄氏度(平均差异0.34,95%置信区间0.14 - 0.53,P = 0.002)。
