夏季闷热潮湿易产生湿疹 大家可能不知道的是 当冬季皮肤出现瘙痒症状时 容易被简单归为皮肤干燥 这也可能是湿疹发出的信号 那么，冬季"湿疹"到底是什么？ 又该如何科学预防呢？ 01 湿疹是不是"湿"出来的 什么是湿疹？ 湿疹是由多种内外因素引起 瘙痒剧烈的皮肤炎症反应 分为急性、亚急性、慢性三期 冬季同样是湿疹的高发期 "湿"是表象 皮肤屏障受损是根源 湿疹的名字会让人误以为是 空气潮湿所致 其实 湿疹的核心问题在于皮肤屏障功能的受损 汗液也会刺激皮肤 导致皮肤屏障功能受损 引发炎症反应 因此湿疹夏季易发作 夏季主要以接触性湿疹、汗疱疹为主 急性的偏多，较为严重 千万别大意 冬季也是湿疹高发期 冬季干燥的环境导致皮肤缺水缺脂 皮肤屏障就像一堵墙 保护我们免受外界刺激 防止水分流失 当这堵"墙"出现裂缝时 皮肤就容易干燥、发炎，甚至引发湿疹 夏季为什么会容易产生湿疹？ 夏季闷热潮湿的环境 会让皮肤屏障功能变弱 同时，夏季露肤度高 皮肤易接触到更多的过敏原（如尘螨） 会直接削弱皮肤的屏障功能 冬季气温低 皮脂腺分泌减少 皮肤容易干燥起屑 屏障功能受损 同时，冬季温差大 冷热刺激容易诱发皮肤瘙痒 冬季主要以干性湿疹为 ...

在某些博主的宣传之下，红霉素软膏被当作"万能药"，用于蚊虫叮咬、湿疹、痘痘、脚气、日常护肤等，甚至还有不少人拿来涂宝宝的"红屁屁"（尿布 疹）。这个"万能药"究竟该怎么用？↓↓↓ 1 红霉素软膏常见的滥用场景 ■ 宝宝的"红屁屁"（尿布疹） "红屁屁"是尿布皮炎的俗称，也被称为尿布疹。这是一种常见的婴儿皮肤病，主要表现为尿布覆盖区域的皮肤发红、炎症，可能伴有皮疹、糜烂或脱皮。 绝大部分情况不建议单用红霉素软膏治疗"红屁屁"。 红霉素软膏被广泛应用于各种病症和场景，几乎是家家必备的常用药膏。但实际上，这些场景大多是滥用。 对于尿布疹的治疗，最核心的元素就是保湿、减少刺激及抗炎。要点如下： 具体的措施是更换尿布，用湿巾/湿毛巾轻柔擦拭干净皮肤，并及时补涂保湿乳；另外可根据炎症的严重程度选择氧化锌软膏、地奈德乳膏等对症外用 药。 此外，"红屁屁"有一定概率出现继发的细菌、真菌感染，如果出现继发感染，需要抗感染治疗。 注意皮肤炎症≠感染，抗感染治疗≠抗炎治疗。 蚊虫叮咬可以理解为虫咬引起的过敏反应。如出现严重的蚊虫叮咬，医生会让患者口服抗过敏药，也可能根据情况涂抹外用糖皮质激素软膏抗炎、促皮疹 消退止痒，大部分叮咬即 ...

Core Viewpoint - Erythromycin ointment is widely used for various conditions, but its application is often inappropriate and constitutes misuse [1][3]. Misuse Scenarios - Erythromycin ointment is promoted as a "universal medicine" for conditions such as insect bites, eczema, acne, athlete's foot, and even for treating diaper rash in infants [3]. - For diaper rash, the primary treatment should focus on moisturizing, reducing irritation, and anti-inflammatory measures rather than solely relying on erythromycin ointment [4]. Treatment Recommendations - Effective treatment for diaper rash includes applying moisturizing creams, minimizing diaper wear time, and using appropriate topical medications based on the severity of inflammation [4]. - In cases of insect bites, while erythromycin ointment can reduce the risk of infection, it does not relieve itching or inflammation [5][6]. - Erythromycin ointment is not effective for eczema, where the treatment should focus on moisturizing and anti-inflammatory agents [7]. - For acne, erythromycin ointment is insufficient as acne treatment requires a multifaceted approach [8]. - Athlete's foot, a fungal infection, necessitates antifungal treatment, which erythromycin does not provide [9]. Appropriate Use Cases - The suitable application of erythromycin ointment is primarily for treating minor burns and wounds where there is a risk of infection [10][11]. - It can be used for minor abrasions and superficial burns after proper cleaning and disinfection, but should not be used continuously for more than one week [12].

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]

Core Viewpoint - The article highlights the increase in skin-related issues during the summer season, emphasizing the need for effective sun protection and awareness of common skin diseases such as sunburn and insect bites [1][3]. Group 1: Common Skin Diseases in Summer - The onset of summer leads to a noticeable rise in patients suffering from skin conditions like sunburn and insect bite dermatitis [3]. - Common allergic skin diseases in summer include sunburn caused by ultraviolet (UV) rays, insect bite dermatitis, urticaria, and eczema [5]. - Sunburn is characterized by symptoms such as redness, small bumps, itching, and peeling skin, particularly in individuals sensitive to UV rays [7]. Group 2: Prevention and Protection Measures - Experts recommend that individuals who are sensitive to UV rays should take precautions such as applying sufficient sunscreen and avoiding direct sunlight [10]. - The recommended amount of sunscreen is half a spoon for the face and one spoon each for the chest and back to ensure effective protection [10]. - For those allergic to certain sunscreens, alternative protective measures include using sun umbrellas, wide-brimmed hats, sun masks, and sunglasses [12].
