Why Summer Heat Triggers Eczema and How to Keep Skin Calm

Summer conditions such as sweating, chlorine exposure and increased UV radiation can aggravate eczema, experts say. Dr. Elizabeth K. Hale of Vacation points out that salt in sweat stings sensitive skin, prompting itching and further barrier damage. Dr. Sapna Palep adds that the body’s cooling response dilates vessels, allowing inflammatory cells to migrate to the skin.

Their guidance centers on a minimalist regimen: a fragrance-free, rich cream or ointment to restore moisture, avoidance of fragrances, essential oils and harsh acids, and the use of mineral sunscreen with zinc oxide or titanium dioxide. They recommend a gentle oat-based cleanser, hyaluronic-acid serums, and petroleum-jelly occlusives to lock in hydration. Additional advice includes short lukewarm showers, loose clothing, and a diet lower in processed sugars to reduce systemic inflammation.
