Winter can be especially challenging for people living with eczema. Colder temperatures, low humidity, and increased exposure to indoor allergens can all contribute to dry, itchy, and inflamed skin. For many patients, eczema doesn’t exist on its own—it’s closely connected to allergies.
Why Eczema Gets Worse in Winter
During winter months, the air holds less moisture, both outdoors and indoors. Heating systems further dry the air, which strips the skin of its natural oils. When the skin barrier is weakened, it becomes more vulnerable to irritation, allergens, and infections.
Common winter triggers include:
Cold, dry air
Indoor heating
Hot showers and baths
Wool or heavy fabrics worn close to the skin
These factors can make eczema symptoms flare more frequently and feel harder to control.
The Link Between Eczema and Allergies
Eczema, also known as atopic dermatitis, is part of the “atopic triad,” which includes allergies and asthma. Many people with eczema also have environmental allergies, food allergies, or both.
In winter, allergy exposure often increases indoors. Triggers may include:
Dust mites
Pet dander
Mold from humidifiers or damp areas
When the immune system reacts to these allergens, it can worsen skin inflammation and itching, leading to eczema flares.
Managing Allergies to Protect Your Skin
Because allergies can worsen eczema, controlling allergy symptoms is an important part of treatment. Allergy testing may help identify triggers, and treatment options such as antihistamines, topical medications, or allergy immunotherapy may reduce flares over time.
If winter eczema flares are frequent, severe, or interfering with daily life, it may be time to seek professional care. Our board-certified allergists can help identify underlying triggers and create a personalized treatment plan to improve both skin health and overall quality of life.
