Core Insights - The article discusses common skin issues during the late summer and early autumn, emphasizing the impact of high temperatures, humidity, and increased insect activity on skin health [1] Group 1: Common Skin Issues - Common skin problems during this season include sunburn, heat rash, summer dermatitis (such as eczema), and insect bite dermatitis [1] - Sunburn symptoms typically appear 2-6 hours after exposure, including redness, burning, and severe cases may lead to blisters and systemic symptoms like fever and fatigue [1] - Summer dermatitis often manifests as small red bumps or blisters on the limbs, causing intense itching and potential skin thickening and pigmentation changes with repeated episodes [1] Group 2: Prevention and Treatment - To prevent heat rash, it is crucial to maintain a cool environment, bathe frequently, and avoid greasy skincare products [2] - For sunburn, the first 6 hours post-exposure are critical for treatment, involving cool compresses and topical corticosteroids [2] - Insect bite dermatitis can be managed by washing the area immediately and applying soothing treatments like calamine lotion or mild steroid creams [3] Group 3: Specific Recommendations - For heat rash, using refrigerated saline or honeysuckle water can alleviate symptoms, and in cases of pustular heat rash, topical antibiotics may be necessary [2] - For insect bites, immediate washing and cold compresses are recommended, especially for bee stings where the stinger should be removed promptly [3] - Fungal infections in humid conditions can be treated with antifungal creams, while eczema management focuses on skin barrier repair and controlled bathing practices [3]

Group 1: Sweaty Eczema (汗疱疹) - Sweaty eczema typically appears on palms and fingers, characterized by clusters of small blisters resembling water droplets [2] - It is a type of eczema that is highly prevalent in late spring and early summer, with symptoms including intense itching, pain from blister fluid, symmetrical distribution, and a tendency to recur [3][4] - Factors contributing to sweaty eczema include allergic reactions to metals, fungal infections, and lifestyle factors such as stress and poor sleep [4][5][6] - Treatment is generally self-limiting, with symptoms resolving in about two weeks if triggers are avoided [7] Group 2: Heat Rash (痱子) - Heat rash, also known as prickly heat, occurs when sweat cannot evaporate due to high temperatures and humidity, leading to inflammation [23][24] - Adults can also suffer from heat rash, especially those in high-temperature jobs or with certain health conditions [25][26] - The most common types of heat rash include white, red, and pustular types, each with distinct characteristics [27][28] - Proper management involves keeping the skin cool and dry, using mild cleansing products, and potentially applying calamine lotion [30][31][32] Group 3: Athlete's Foot (脚气) - Athlete's foot is a fungal infection characterized by itching, peeling, and blisters, often exacerbated in hot and humid conditions [35] - It is important to differentiate between foot odor and athlete's foot, as not all foot odor indicates a fungal infection [36] - Common misconceptions about treatment include the ineffectiveness of vinegar and iodine foot soaks, which do not adequately address the fungal infection [38][39][40] - Effective treatment requires antifungal medications, and adherence to the full treatment course is crucial to prevent recurrence [44]
