冬季抵御寒冷的妙招

冬季戴上帽子,可以减少头部的散热量,同样能达到周身保暖的目的.在更加严寒的时候,还应戴上口罩和手套.俗话说：“寒从脚下起.”在严冬,还必须穿上棉鞋,注意脚部保暖.

一、身体锻炼法：这是预防冻疮的最佳办法,通过身体锻炼而提高肌体对寒冷的适应能力.

二、御寒准备法：冬季在户外工作时,一定要吃饱,穿暖,做好各种御寒准备.如戴手套,帽子,穿棉鞋.体内衣物要保持干燥.易受冻的耳,脸,手,脚等部位要经常擦些油脂。

①、要穿着适当厚度的保暖御寒衣服.

②、要勤晒被褥.大家知道,空气是热的不良导体,其散热系数仅为0.027.所以增加被褥内的空气量就等于提高了保暖能力.被褥经过日晒,变得蓬松,不仅增加了空气量,而且还增加了厚度.所以盖着晒过的被子,总觉得很暖和.

③、在冬季宜穿深色衣服.研究表明,黑色衣服吸收太阳辐射为88％,军绿色为57％,白色为20％.所以深色衣服可以使人体多获得一些热量,具有保暖的功能.

三、冬季合理膳食也可以预防寒冷

①多吃主食，适当吃点羊肉、鹌鹑和海参。蛋白质、脂肪和碳水化合物被称为产热营养素。所以冬季我们要适当增加主食和油脂的摄入，保证优质蛋白质的供应。狗肉、羊肉、牛肉、鸡肉、鹿肉、虾、鸽、鹌鹑、海参等食物中富含蛋白质及脂肪，产热量多，中医认为有益肾壮阳、温中暖下、补气生血的功能，御寒效果最好。
