Yes, coffee can trigger eczema flare-ups in some people. Eczema is an inflammatory skin condition that causes red, itchy patches of skin, and can be worsened by allergens, irritants, and stress. Coffee is a stimulant and can trigger inflammation in the body, which can exacerbate eczema symptoms. Additionally, coffee is a common allergen, so if you have an allergy to it, drinking coffee can trigger a reaction that can cause eczema flare-ups.
If you have eczema, it is best to avoid drinking coffee or limit your intake to one cup a day. Additionally, there are several other factors that can contribute to eczema flare-ups, such as stress, certain soaps and detergents, heat and humidity, and certain fabrics. If you are unsure what is triggering your eczema, it is best to speak to a doctor or dermatologist to receive personalized advice.
