Skin Itching in Hot Weather - Causes and Solutions

Skin diseases are prevalent in daily life, manifesting in diverse symptoms, with itching being a prominent one. Skin itching can be exceedingly uncomfortable, emphasizing the need to comprehend its underlying causes for apt remediation. Some individuals encounter severe itching during hot summer days, which abates in other seasons. Let's delve into the reasons behind this phenomenon.

Hot weather fosters increased sweating, which, coupled with ultraviolet radiation and dust irritation, can culminate in skin allergies known as summer dermatitis. Some individuals may also develop inflammatory skin conditions like eczema during hotter days, often due to exposure to airborne allergens. In such instances, avoiding excessive heat, maintaining skin cleanliness and moisture, and administering topical medications tailored to rash characteristics are advisable. Oral medications may also be prescribed for severe cases. When outdoors, safeguarding the skin from UV rays through sunscreen, hats, or umbrellas is crucial.

Symptoms of Summer Dermatitis

Summer dermatitis is a seasonal inflammatory skin disease provoked by hot weather, typically occurring between June and August, and is more common among adults. Lesions typically manifest symmetrically on the trunk and limbs, with the lower legs being particularly affected. They present as extensive patches of bright red skin adorned with pinhead to millet-sized papules and pustules. The intense itching can lead to scratching, resulting in scratch marks, blood crusts, and ultimately, rough, thickened skin. This condition often improves or resolves spontaneously when the weather cools, but it can recur annually. To manage summer dermatitis, maintaining indoor ventilation and cooling for a comfortable temperature, wearing loose, sweat-absorbent clothing to keep the skin dry and clean, bathing with lukewarm water, and applying powder post-drying are recommended. Topical treatments, including 1% phenol calamine lotion, 1% menthol calamine lotion, 1% menthol alcohol, or glucocorticoid topical preparations, can effectively manage the symptoms.
