为了避免在寒冷的环境下冻伤，有一个简单的方法来记住这四个步聚，即COLD。
1. C (Cover)：戴上帽子和围巾来保护头、颈和耳朵。穿连指手套而不是分指的；
2. O (Overexertion)：避免流汗，在寒冷环境下潮湿后会很可怕。
3. L (Layers)：多穿几层轻的，蓬松的衣服胜过一件厚重的衣服。外套要防风和防水。
4. D (Dry)：保持干燥，特别注意易进雪的鞋顶、腕部的手套和脖子这三个部位。
此外，吃雪很有趣，但会加快失温；喝酒让人觉得温暖，但实际上却会降低身体的保温能力。

To avoid cold-related injuries, here is a simple way to remember four basic steps to staying warm. Think of COLD -- C.O.L.D.
The C stands for cover. Wear a hat and scarf to keep heat from escaping through the head, neck and ears. And wear mittens instead of gloves. In gloves, the fingers are separated, so the hands may not stay as warm.
The O stands for overexertion. Avoid activities that will make you sweaty. Wet clothes and cold weather are a bad mix.
L is for layers. Wearing loose, lightweight clothes, one layer on top of another, is better than wearing a single heavy layer of clothing. Also, make sure outerwear is made of material that is water resistant and tightly knit.
Can you guess what the D in COLD stands for? D is for dry. In other words, stay as dry as possible. Pay attention to the places where snow can enter, like the tops of boots, the necks of coats and the wrist areas of mittens.
And here are two other things to keep in mind, one for children and the other for adults. Eating snow might be fun but it lowers the body's temperature. And drinking alcohol might make a person feel warm. But what it really does is weaken the body's ability to hold heat.
