Winter treks 冬季行山
Winter clothing 冬季服飾
In order to spend time and function outdoors in a winter climate, it is necessary to understand the human body’s ability to regulate its own temperature. Because our bodies are naturally suited for a more tropical climate, we need clothing and equipment to keep us dry, warm and safe.
The clothes you choose and how you combine them are both very important. The garments should be designed to allow good mobility and ventilation. The air inside the garment is a key ingredient in the insulation since air conducts the cold poorly. Clothing, gloves and shoes that fit too tightly allow less space for air, and therefore are not good insulators. (On the other hand, if you are wearing very loose clothing it is difficult for your body to warm up the air inside.)
為了在寒天之下進行戶外生活，維持身體正常運作，我們必須了解人體調節體溫的能力。由於人體構造適合熱帶氣候，因此進入寒帶地區時，我們需要利用衣物和裝備來維持乾燥、溫暖和安全。
您所選擇的衣物和搭配方式非常重要，服裝在設計上必須讓身體活動自如，提供良好的透氣性。空氣的導寒能力差，因此衣物裡面充滿的空氣是保暖的關鍵。太緊的衣物、手套和鞋子沒有足夠的空間可以容納空氣，因此無法有效保暖。（反之，過於寬鬆會使身體無法有效溫熱空氣。）
