A Dermatologist’s Approach to Eczema in Cold Weather
For the estimated 10 to 15 percent of Minnesotans living with eczema (atopic dermatitis), winter is often the most challenging season. The combination of bitter cold outdoor air, low humidity, harsh winds, and dry indoor heat creates conditions that strip moisture from the skin and trigger painful flare-ups. Managing eczema through a Minnesota winter requires a proactive, multi-layered approach.
At Clarus Dermatology, our board-certified dermatologists work with eczema patients throughout the year, but winter visits increase significantly as patients struggle with worsening symptoms. This guide offers a dermatologist’s perspective on keeping eczema under control when temperatures drop.
Why Minnesota Winters Are Especially Hard on Eczema
Dramatic Drops in Humidity
Minnesota’s relative humidity can plummet during winter, particularly indoors. Forced-air heating systems — which are standard in most Minnesota homes — push warm, dry air through living spaces for months on end. Indoor humidity levels can fall below 20 percent, far lower than the 40 to 60 percent range that is ideal for skin health.
This dry environment accelerates transepidermal water loss (TEWL), the process by which moisture evaporates from the skin’s surface. For individuals with eczema, whose skin barrier is already compromised, this leads to intensified dryness, cracking, and itching.
Temperature Extremes
Moving between sub-zero outdoor temperatures and heated indoor spaces multiple times per day creates thermal stress on the skin. These rapid shifts can trigger eczema flares, particularly on exposed areas such as the face, hands, and neck.
Heavy Clothing and Irritants
Winter in Minnesota means layers of clothing — wool sweaters, heavy coats, scarves, and insulated gloves. Rough or scratchy fabrics can irritate sensitive eczema-prone skin, while tight-fitting layers can trap sweat against the body and exacerbate symptoms.
Strategies for Managing Winter Eczema
Moisturize Aggressively and Consistently
The single most important step in winter eczema management is consistent, generous moisturizing. Apply a thick, fragrance-free moisturizer or ointment within three minutes of bathing to lock in hydration. Look for products containing ceramides, hyaluronic acid, or colloidal oatmeal, which help restore and protect the skin barrier.
Ointments (such as petroleum jelly) and cream-based moisturizers provide more effective barrier protection than lotions, which contain higher water content and evaporate more quickly. Apply moisturizer at least twice daily, and more often to particularly dry areas such as the hands, elbows, and lower legs.
Modify Your Bathing Habits
Long, hot showers feel wonderful in a Minnesota winter but can worsen eczema by stripping natural oils from the skin. Keep showers and baths lukewarm (not hot) and limit them to 10 to 15 minutes. Use gentle, fragrance-free cleansers rather than traditional soap, which can be drying and irritating.
Use a Humidifier
Running a humidifier in your bedroom and main living areas can help counteract the drying effects of forced-air heating. Aim for indoor humidity levels between 40 and 50 percent. Clean your humidifier regularly to prevent mold and bacteria growth.
Choose Clothing Wisely
Wear soft, breathable fabrics such as cotton or bamboo against the skin. If wool is needed for warmth, layer it over a smooth cotton base layer to prevent direct contact with sensitive skin. Remove layers promptly when moving indoors to prevent overheating and sweating.
Protect Exposed Skin Outdoors
Apply a thick layer of moisturizer or a barrier cream to your face and hands before heading outside. Wear soft cotton-lined gloves rather than rough wool or synthetic materials. Consider a scarf or balaclava made of gentle fabric to protect the face from wind and cold.
Medical Treatments for Winter Eczema Flares
Topical Corticosteroids
For active flares, your dermatologist may prescribe topical corticosteroids of varying strengths depending on the severity and location of the eczema. These medications reduce inflammation and itching quickly but should be used as directed to avoid potential side effects with prolonged use.
Topical Calcineurin Inhibitors
Non-steroidal prescription options such as tacrolimus and pimecrolimus are effective for sensitive areas including the face and eyelids. These medications can be used for longer periods and are a valuable tool in managing chronic eczema.
Newer Targeted Therapies
For moderate to severe eczema that does not respond adequately to topical treatments, your dermatologist may recommend newer medications including biologic agents (such as dupilumab) or JAK inhibitors. These treatments target specific components of the immune system involved in eczema and have shown significant results in clinical trials and real-world practice.
Wet Wrap Therapy
For severe flares, your dermatologist may recommend wet wrap therapy — applying a damp layer of soft fabric over medicated skin, then covering with a dry layer. This technique enhances medication absorption and provides intensive hydration. It is particularly useful for nighttime treatment of severe winter flares.
When to See a Dermatologist for Eczema
If your eczema is disrupting your sleep, limiting daily activities, or not improving with over-the-counter moisturizers and treatments, it is time to see a dermatologist. Signs that warrant prompt evaluation include widespread redness, open or weeping sores, signs of skin infection (increased warmth, pus, or crusting), and eczema that affects your quality of life.
