What is a common trigger for eczema flare-ups?

Cold weather is a well-known trigger for eczema flare-ups because it can lead to dry skin, which exacerbates the symptoms of eczema. In colder temperatures, the humidity levels decrease, causing skin to lose moisture more rapidly. This dryness can result in increased itching, redness, and irritation, prompting flare-ups of eczema symptoms. Additionally, cold air can strip the skin of its natural oils, making it more prone to irritation and inflammation, which are hallmark characteristics of eczema.

In contrast, high humidity often allows the skin to retain moisture, which may help soothe symptoms rather than aggravate them. Warm baths, while potentially beneficial for hydration if followed by moisturizing, can exacerbate dryness if not managed carefully. Frequent sunscreen application is important for protecting the skin from UV damage, but it's not typically considered a trigger for eczema.
