    冬季天氣寒冷的時(shí)候,腳趾是身體最易受傷害的部位。根據(jù)下面的步驟,保護(hù)腳趾和雙腳其他地方暖和。
    Your toes are the most vulnerable part of your body when it comes to the cold. Keep them – and the rest of your feet – toasty with these steps.
    你需要
    You Will Need
    兩雙棉質(zhì)襪子
    Two pairs of cotton socks
    防水鞋子或靴子
    Waterproof shoes or boots
    步驟
    Steps
    1.保持雙腳干燥
    STEP 1 Keep them dry
    容易出汗的雙腳在寒冷的天氣中幾個(gè)小時(shí)后就會(huì)變得冰冷。穿上襪子之前確保雙腳干燥。
    Sweaty feet become cold feet after a few hours in cold weather. Make sure you feet are dry before you put your socks on.
    2.穿上棉質(zhì)襪子
    STEP 2 Put on cotton socks
    穿上一對(duì)棉質(zhì)的襪子。確保不是羊毛的或合成布料的。這兩種布料都容易鎖住水分。
    Slide on a pair of cotton socks. Make sure they’re not wool or synthetic: Both can trap moisture.
    考慮穿輕薄的襪子。盡管可能與你的直覺(jué)相反,薄襪子更容易保暖,因?yàn)椴粫?huì)讓腳那么容易出汗。
    Consider using thin, lightweight socks. Though it may seem counterintuitive, thin socks can actually keep your feet warmer because they don't cause you to sweat as much.
    3.撫平褶皺
    STEP 3 Smooth out wrinkles
    撫平襪子上的褶皺,這樣就不會(huì)夾在腳趾之間。
    Smooth out the wrinkles in your socks so they don't jam between your toes.
    4.穿上鞋子
    STEP 4 Slip on your shoes
    穿上防水靴子或鞋子。
    Slip on your waterproof shoes or boots.
    確保你的鞋子或靴子合腳。太大或太小的鞋子都會(huì)讓腳冰冷,會(huì)讓空氣和水分進(jìn)去,或者妨礙血液循環(huán)。
    Make sure your shoes or boots fit well. Shoes that are too big or small can make your feet cold, either by letting in air and water, or by cutting off circulation.
    5.水上行走
    STEP 5 Walk on water
    大膽行走——直接走過(guò)那個(gè)水坑。多準(zhǔn)備一雙襪子,以防靴子不像你認(rèn)為的那樣防水。
    Go ahead – walk right through that puddle. Just bring along an extra pair of socks in case your boots aren't as waterproof as you thought.
    你知道嗎?登山的時(shí)候,每向上攀爬1000英尺,溫度就會(huì)平均下降2.5華氏度。
    Did you know? When hiking, the temperature drops an average of 2 ? degrees Fahrenheit for every 1,000 feet you climb.
