12 Cold Weather Myths Debunked: What You Need to Know About Dressing for Warmth After 50

3. Myth: Cotton is fine for cold weather because it’s comfortable

Cotton feels soft and familiar, but it holds moisture. When cotton gets wet from sweat or weather, it stays wet and loses insulating power. That wetness sits against your skin and conducts heat away, leaving you colder. For older adults who may have circulation differences, staying dry is especially important. Choose fabrics that move moisture away and keep insulating ability when damp—merino wool and technical synthetic blends are good choices. Merino is naturally odor-resistant and warm even when slightly damp, while synthetic baselayers dry quickly and resist chilling. Use cotton for casual, dry indoor wear—but for active spells, outdoor chores, or long walks, swap the cotton next-to-skin layer for merino or a synthetic alternative. That simple swap can make the difference between a comfortable outing and a shivery one.

4. Myth: Bigger, baggier clothing is always warmer

People often assume that looser equals warmer because it seems like more air is trapped. But fit matters in specific ways. A snug base layer sits close enough to the skin to move moisture away, while a slightly looser insulating layer traps warm air. Super-baggy garments can let cold air circulate and reduce the effectiveness of inner layers. For comfort and mobility, aim for a close-fitting base, a comfortably insulating midlayer, and an outer layer that gives room for the midlayer without being excessively loose. This approach keeps warmth where you need it while allowing movement and reducing trip hazards from dragging hems or sleeves. For older adults, proper fit also helps prevent garments from catching when reaching or bending, and it promotes better circulation by avoiding constriction at key points like wrists and ankles. In short: fit thoughtfully rather than assuming "bigger is warmer."
