What triggers dyshidrosis?

Healthcare workers and researchers don’t know exactly what causes dyshidrosis. A combination of triggers can cause dyshidrosis flare-ups, including:

• Immune system activation: If you have dyshidrotic eczema, your immune system reacts to minor irritants or allergens. This overreaction can inflame your skin.
• Allergies: Exposure to certain substances, including cement, nickel, cobalt and chromium, may trigger dyshidrotic eczema. Other allergies, including hay fever (allergic rhinitis) or food allergies, may also cause flare-ups.
• Moisture: Frequently sweaty or wet hands or feet may trigger dyshidrotic eczema.
