高温潮湿天气,对大脑健康有什么伤害
摘要
高温可能会对我们的生理和心理健康产生负面影响。高温和高湿等天气条件还会通过影响大脑神经化学来损害精神表现。本篇为您深度解读高温对大脑的影响机制。高温潮湿天气,注意防暑。
炎热潮湿的天气里,您在是否无法专注地思考或执行于一项任务?并不是您一个人这样。当环境温度上升到令人不舒服的水平时,许多人会经历这种脑雾。越来越多的证据表明,高温天(>30°C)可能会对我们的生理和心理健康产生负面影响。环境气温高会给心血管系统带来很大的压力来维持体温。由于热应力,气温升高(从 22.8°C 到 30.6°C)会使机体性能下降 5%。高温和高湿等天气条件还会通过影响大脑神经化学来损害精神表现。

高温天气个人应尽可能远离阳光,多喝水,并在需要时找地方避暑。包括避免在中午高峰时段暴露在阳光下、穿着宽松的浅色衣服以及避免在高温下进行剧烈的体力活动。
