She has listed out some ways which can help people brave cold during their exercise routine:
People should dress in layers, which they can remove as soon as they start to sweat, then put back on as needed. First, put on a thin layer of synthetic material, such as polypropylene, which draws sweat away from your body; and avoid cotton, which stays wet next to your skin. Next, add a layer of fleece or wool for insulation. Top this with a waterproof, breathable outer layer.
Protect your extremities from frostbite by wearing a thin pair of gloves under a pair of heavier gloves or mittens lined with wool or fleece. Also, wear a thermal hat or headband to protect your ears.
Even if it's not as obvious as in the summer, people will still sweat during cold-weather workouts and pushing yourself, so drink plenty of water.
