Dry winter skin and the choice of fabric
Short answer: Dry winter skin gets worse from friction with rough fabric. A smooth layer against the skin reduces the irritation that otherwise comes on top.
Why skin gets dry in winter
Cold outdoor air holds little water, and heated indoor air is drier still. The skin loses moisture around the clock and the skin barrier weakens. Then everything is felt more keenly.
What the fabric does
Rough fibres rub against a weakened skin barrier every time you move. Smooth fibres such as bamboo viscose glide instead of rubbing. See bamboo underwear for women.
The other measures
Shorter and cooler showers, moisturiser while the skin is slightly damp, and no perfumed detergent. See bamboo long sleeved t-shirts for men and bamboo bedding.
