消暑不当很伤身 有些“热养”更凉爽

2017-08-29 09:50:36   央广网

洗凉水澡、吃冷饮、吹空调……这些看似可以使人凉爽的办法,其实恰恰起不到消暑的积极作用。稍有不慎,反易伤身。下面的三个例子,看看是否有你的影子?

现象:

夏季胃口差 许是寒凉食物吃多了

每到炎热的夏天,学生小李都会吃各种冰爽的食物解暑。上周末的晚上,小李一口气吃了半个凉西瓜,后来又吃了两个雪糕。结果后半夜突然上吐下泻,吃些药才好转。不过打那天开始,小李的食欲就特别差,而且天一热,在外边走上一圈就头晕脑胀。

解析:中国人力资源和社会保障部教育培训重点养生专家赵利仁说,很多人在夏季会放弃正常的一日三餐,经常吃些冰凉的西瓜、冷饮、凉菜作为替代品,以利解暑。其实不然,中医讲,夏季养阳,阳气足,人才不易中暑,如果这个阶段食用大量的凉性食物,身体的热气发不出,被瘀住留在体内,反倒容易中暑。而且还会伤脾胃,导致胃口越来越差,耐热性也随之降低。

支招:夏季适当食用用高蛋白的食物制成的热汤,以热制热,身体发汗,将热气带出,反倒利于降温消暑。因为“热”刺激了体温调节中枢,它马上工作起来,通过一系列的神经反射调节,使皮肤毛细血管和毛孔扩张,血流量增加,汗腺分泌增强,水分通过皮肤表面的毛孔渗出体外,以达到散热降温的目的。此外,中医讲“冬吃萝卜夏吃姜”,夏天也可用姜等食物来温中散寒,把生姜、大枣一起煮水,调以适量红糖,温中散寒,健运脾胃

现象:

空调开了一夜 早上起床后落枕了

夏天闷热的天气让刘鑫(化名)好多天无法一觉睡到天亮。“每天上班都得用脑,休息不好真无法专注工作。”于是,从六月上旬开始,刘鑫就每天开空调睡觉。本以为这回能睡个好觉,没想到第二天早上起床后,刘鑫就“落枕”了。整个白天,不仅脖子不舒服,整个人也感觉异常乏力。

解析:刘鑫出现的这种情况,和睡眠环境的温度息息相关。因为很多人会在入睡前将空调打开,一开就是几个小时,室内温度偏凉,人体毛孔闭塞,血液正常的运行受到影响,脖子就易僵硬,这就是夏季多发落枕的原因所在。

此外,夏季是人体阳气最盛、推陈出新旺盛期间。而寒邪非常易损阳气,会让整个人变得厌倦无力。所以,即使在夏季,假如不留意保暖,寒邪同样会侵袭体内,导致身体出现显著的寒象。因此,人体要尽量习惯、适应高温天,顺应自然,调整好身体和心理的状态。
