This study investigated the effect of cold-water hand immersion on selective attention as measured by the Stroop Color Word Test in nomorbaric normoxia and hypoxia. Ten healthy men rested for 60 min, after which they immersed their non-dominant hand into 5 °C water for 15 min. The interference score of the Stroop Color Word Test and thermal sensation were measured at baseline in the final 5 min of resting and in the final 5 min of cold water hand immersion. The interference score was not influenced by hypoxia but was found to be significantly improved compared to resting in both conditions during cold water hand immersion. Selective attention improved during 15 min of cold-water hand immersion, with increased thermal sensations rated as "very cool" of the immersed arm. Cold-water hand immersion may be helpful in improving cognitive function in normoxia and normobaric hypoxia.
本研究调查了冷水手部浸泡对斯特鲁普颜色-文字测试（Stroop Color Word Test）选择性注意的影响，该测试在常压常氧和缺氧条件下进行。10 名健康男性休息 60 分钟后，将非优势手浸入 5°C 的水中 15 分钟。在基线时、休息的最后 5 分钟以及冷水手部浸泡的最后 5 分钟，测量斯特鲁普颜色-文字测试的干扰分数和热感觉。缺氧对干扰分数没有影响，但与休息时相比，在两种情况下，冷水手部浸泡都显著改善了干扰分数。选择性注意力在 15 分钟的冷水手部浸泡过程中得到改善，手臂浸入时的热感觉被评为“非常凉爽”。冷水手部浸泡可能有助于改善常压常氧和常压缺氧条件下的认知功能。
