Winter's cold weather, low humidity, and indoor heating can exacerbate skin conditions like eczema and psoriasis, and increase general dryness. Experts advise proactive measures to prevent flare-ups, emphasizing the importance of moisturizers and emollients recommended by dermatologists. Reduced sunlight exposure can also worsen psoriasis symptoms. Maintaining skin health during winter requires consistent care to protect the skin barrier and alleviate itching, redness, and scaling.
