Why Winter Weather Harms Your Skin and How to Protect It Effectively

Winter weather poses unique challenges for human skin, as cold air, indoor heating, and hot showers weaken the skin's natural barrier, leading to dryness, irritation, and the exacerbation of chronic conditions. Dr. Ayelet Ollch, head of the Pediatric Dermatology Service at Shaare Zedek Medical Center, explains how to protect the skin during the colder months.

The skin's outer layer acts as a vital shield preventing moisture loss and blocking allergens. However, winter air and indoor heating deplete humidity, causing moisture loss and weakening this barrier. This often results in xerosis, characterized by tightness, roughness, and itching, particularly on the shins and arms. For individuals with atopic dermatitis, or eczema, winter conditions can trigger severe flare-ups requiring targeted anti-inflammatory treatments or biologics.

Protecting Hands and Lips

Hands are among the first areas affected due to constant exposure to water, soap, and temperature drops, which can cause contact dermatitis and painful cracks. Dermatologists recommend using gentle cleansers, applying rich hand creams frequently, and wearing gloves during outdoor activities or housework. Lips, with their delicate skin, are also prone to severe drying and chapping. Experts advise avoiding lip-licking, which worsens irritation, and using protective balms regularly.

Managing Psoriasis and Keratosis Pilaris

Conditions like psoriasis often worsen in winter due to reduced ultraviolet light exposure, lower vitamin D levels, and seasonal infections such as strep throat, which can trigger guttate psoriasis in children. Meanwhile, keratosis pilaris, commonly known as "chicken skin," becomes more pronounced in winter as dry air highlights tiny bumps around hair follicles. Maintaining a consistent moisturizing routine and protecting the skin barrier remain essential steps to preventing winter skin distress.
