Kassel, Germany  - Even though the wintry weather in central Europe is right for hikes in the snow, hikers should not exert themselves, warned Hans-Ulrich Rauchfuss, president of the Kassel-based German Hiking Association.

Exercise in cold weather was generally good for the body, Rauchfuss added. But people who exerted themselves or perspired heavily and then cooled down could easily put excessive demands on their body's defences. So hikers should pace themselves.

Appropriate dress is also important, he pointed out. The "onion look" or several layers of clothing protected most effectively from the cold. A fabric that "breathes" is best for the bottom layer as it keeps sweat from sticking to the skin. Then comes a shirt or light sweater. On top of that, hikers should wear a fleece sweater and a waterproof jacket as the outermost layer, Rauchfuss said.

He also advised winter hikers to breathe through the nose rather than the mouth. This warmed the cold air. Otherwise, Rauchfuss said, the chilly air could strain the respiratory tract and lead to a cold. When the weather is particularly bone-chilling, he added, it was advisable to wear a cloth or scarf over the nose and mouth. (dpa)
