How can warm weather trigger eczema?
Warm skin is itchy skin. Heat at the skin’s surface feels prickly can our response is to scratch. People with eczema tend to hold heat at the skin’s surface for longer, which means warmer and itchier and skin.
Sweat also plays a part in triggering eczema flare-ups. During warm weather, we sweat to try and regulate our body temperature. Sweat is made up mostly of water. When water sits on the skin it causes evaporation on the skin’s surface which takes away hydration from the skin. The makes the skin dry and itchier. Sweat also contains trace amounts of chemicals such as zinc, magnesium, calcium and iron, which may be irritating to the skin. In high humidity, sweat doesn’t evaporate easily which can lead to a build-up of these chemicals, causing itching and irritation.
