Atopic dermatitis: why it worsens in winter

Atopic dermatitis is a chronic skin condition that affects adults and children, often presenting with dry skin, itching, and redness. Those who suffer from it know well: when winter arrives, the symptoms seem to intensify. But why does this happen? And, most importantly, what can be done to alleviate the discomfort?

Cold and dry air: the enemies of atopic skin

During winter, the skin is put to the test. Lower temperatures reduce sebum production, the skin’s natural protective barrier, making it more vulnerable. The situation is worsened by dry air, both outside and in heated indoor environments. Home heating further lowers humidity levels, causing water loss in the skin (known as transepidermal water loss). The result? Tight skin, itching, irritations, and flare-ups of dermatitis.

Even constant temperature changes stress atopic skin. These fluctuations can promote inflammation, making the skin more sensitive and prone to micro-lesions. Additionally, oxidative stress from free radicals increases in winter, further weakening the skin barrier.

Often, small daily habits worsen symptoms without even realizing it.
Too hot showers, harsh cleansers, or wool garments in direct contact with the skin are among the main “saboteurs” of skin balance. Diet can also have an impact: a diet low in essential fatty acids (like omega-3s) and antioxidants can make the skin drier and more reactive.

How to protect atopic skin in winter

• Constant hydration: apply an emollient cream several times a day, especially after showering, to restore the hydrolipidic film.
• Gentle cleansers: opt for soap-free formulations with mild surfactants.
• Smart clothing: wear cotton garments in contact with the skin, avoiding synthetic fibers or wool.
• Humid environments: use a humidifier at home to maintain a good humidity level.
• Watch your diet: include foods rich in omega-3s (oily fish, flaxseeds) and natural antioxidants (colorful fruits and vegetables).
