Why does cold weather increase allergies and skin irritations?

As temperatures and humidity drop, our skin faces a series of challenges.

With the arrival of winter and cold temperatures, many people begin to remember or realize that our skin reacts differently to the cold weather. The coldest season of the year not only brings a desire to stay warm, but it can also intensify skin problems such as allergies and irritation.

In an interview with Earth youDermatologist specializing in skin health, Patrícia Elias, says it’s important to remember that the intense cold of winter tends to dry out the skin because it reduces the natural production of oil, which works as a protective barrier.

This decrease in the lipid barrier makes the skin more vulnerable to external agents, such as pollutants and allergens, facilitating the appearance of irritation and allergies. It also reduces the production of sweat, whose function is to maintain body temperature and eliminate toxins.

“Another important factor is vasoconstriction of blood vessels, a natural response to cold, which can reduce the supply of nutrients and oxygen to the skin, compromising its protective function,” she explains.

7 tips to protect yourself from winter ailments

The most common cold-weather allergies and irritations include atopic dermatitis, a chronic inflammation characterized by dry skin and intense itching, and cold urticaria, an allergic reaction that manifests as redness, swelling, and itching in areas exposed to the cold.

Another common condition is contact dermatitis, especially when using heavier or synthetic fabrics, which can aggravate skin sensitivity.

To protect yourself from these allergies during the winter, keeping your skin hydrated is essential. This includes using moisturizers rich in plant oils and butters that help retain moisture in the skin. The expert emphasizes that it is important to apply moisturizer immediately after showering, while the skin is still damp, to maximize absorption.

It is also important to avoid very hot and prolonged baths, as hot water can remove the skin’s natural oils and excess soap. Additionally, sunscreen is still necessary, even in winter, to protect the skin from UV rays that penetrate the clouds.
