冬季抵禦寒冷的妙招
冬季戴上帽子,可以減少頭部的散熱量,同樣能達到周身保暖的目的.在更加嚴寒的時候,還應戴上口罩和手套.俗話說：“寒從腳下起.”在嚴冬,還必須穿上棉鞋,註意腳部保暖.
壹、身體鍛煉法：這是預防凍瘡的最佳辦法,通過身體鍛煉而提高肌體對寒冷的適應能力.
二、禦寒準備法：冬季在戶外工作時,壹定要吃飽,穿暖,做好各種禦寒準備.如戴手套,帽子,穿棉鞋.體內衣物要保持幹燥.易受凍的耳,臉,手,腳等部位要經常擦些油脂。
①、要穿著適當厚度的保暖禦寒衣服.
②、要勤曬被褥.大家知道,空氣是熱的不良導體,其散熱系數僅為0.027.因此,增加被褥內的空氣量就等於提高了保暖能力.被褥經過日曬,變得蓬松,不僅增加了空氣量,而且還增加了厚度.因此,蓋著曬過的被子,總覺得很暖和.
③、在冬季宜穿深色衣服.研究表明,黑色衣服吸收太陽輻射為88％,軍綠色為57％,白色為20％.因此,深色衣服可以使人體多獲得壹些熱量,具有保暖的功能.
三、冬季合理膳食也可以預防寒冷
①多吃主食，適當吃點羊肉、鵪鶉和海參。蛋白質、脂肪和碳水化合物被稱為產熱營養素。所以，冬季我們要適當增加主食和油脂的攝入，保證優質蛋白質的供應。狗肉、羊肉、牛肉、雞肉、鹿肉、蝦、鴿、鵪鶉、海參等食物中富含蛋白質及脂肪，產熱量多，中醫認為有益腎壯陽、溫中暖下、補氣生血的功能，禦寒效果最好。
Winter hat, can reduce head heat dissipating capacity, to achieve the same body warm. In more cold when, should also wear masks and gloves. As the saying goes:" cold starting from the foot." in the winter, also must wear shoes, foot warm attention.One, body exercise: This is the best way to prevent frostbite, through physical exercise to improve body on the cold adaptation.Two, prepare method: cold winter outdoors, must satiate wear warm, warm, do all kinds of preparation.

Vulnerable to the cold face, ears, hands, feet and other parts to rub some oil.First, to wear the appropriate thickness of the warm warm clothes.II, to ground drying clothes. As we all know, air is a poor conductor of heat, the heat dissipation coefficient is 0.027. Therefore, increasing the volume of air within the bedding is equivalent to raising the thermal capacity. Bedding after sun, fluffy, not only increases the amount of air, but also increased the thickness. Therefore, covered with sunburnt quilt, always feel very warm.Thirdly, in the winter should wear dark clothes. Research shows, black clothes absorb solar radiation for 88%, army green 57%, white 20%. Therefore, dark clothes can make human body obtains some heat, with thermal insulation function.In three, a reasonable diet can prevent cold winterThe eat more staple, appropriate to eat meat, quail and sea cucumber. The protein, fat and carbohydrates known as heat nutrients. So, we should appropriately increase winter staple foods and the intake of fat, guarantee the supply of high quality protein. Dog meat, mutton, beef, chicken, shrimp, venison, dove, quail, sea cucumber and other foods rich in protein and fat, produce more calories, TCM believes that a beneficial kidney and strengthening yang, invigorating qi and promoting blood, to warm the function, to keep out the cold effect is best
