来源： 人民日报 手上的小伤口一直没愈合、难缠的炎症反复发作、身边有人感冒一下就被传染……正值开年，一些人的免疫系统却频繁出状况。 进入1月，由于天气、病毒流行状况等因素，原本保护着我们的免疫系统很容易失衡。 本文邀请专家解读，教你在此时科学激活免疫能力，为一整年的好身体打下基础。 免疫系统迎来双重考验 上海市社区卫生协会全科医学专业委员会委员潘向东表示，这个季节，免疫系统即将面临双重考验。 一方面，寒潮频繁导致人体代谢消耗增加，间接挤占了用于维持免疫功能的生理资源； 另一方面，后续天气转暖，病毒细菌的生存与传播条件改善，活跃度增强，对免疫系统的"识别与清除能力"提出更高要求。 此时通过科学干预激活免疫潜能，能从容应对健康风险，维护全年免疫稳态。 4件事很伤免疫力 正常情况下，免疫系统处于平衡状态，但生活中一些不良习惯可能扰乱免疫系统，引发不适或疾病。 动得少，招来慢性病 缺乏运动，可能导致免疫力快速下滑。 研究发现，肌肉组织下降一成时，更易出现感染；减少两成时，会感到疲乏无力，伤口不易愈合；减少三成时，人体会变得虚弱。 睡眠差，扰乱内分泌 好睡眠有助改善免疫功能，降低体内炎症水平。如果长期劳累而得不到充足休 ...

Core Viewpoint - The article discusses the onset of cold symptoms, particularly sore throat, as a signal of the immune system's response to viral infection rather than the beginning of the illness itself [6]. Group 1: Understanding Sore Throat and Immune Response - Sore throat is often the first symptom of a cold, indicating that the immune system is attacking the virus [6]. - When viruses invade throat cells, they trigger a response from the immune system, which sends immune cells to the site of infection and releases inflammatory mediators that cause pain [3][6]. - The immune response can lead to additional symptoms such as nasal congestion and fever, especially in young children whose immune systems are still developing [3][6]. Group 2: Prevention of Colds - Common remedies like vitamin C and various juices do not effectively prevent or shorten the duration of colds; they primarily provide symptomatic relief [7]. - Effective prevention methods include: 1. Frequent hand washing to eliminate viruses from hands [8]. 2. Wearing masks in crowded or poorly ventilated spaces to block virus transmission [9]. 3. Ensuring proper ventilation in indoor spaces to dilute airborne viruses [10]. 4. Vaccination against specific pathogens that cause respiratory symptoms, such as the flu vaccine [11]. Group 3: Relief Measures for Sore Throat - While immediate relief from sore throat is not possible, several methods can provide comfort: - Drinking warm or cold beverages, such as tea with honey or lemon [12]. - Consuming cold desserts like ice cream [13]. - Sucking on hard candies for older children [14]. - Gargling with warm salt water for children aged six and above [15].

Core Insights - The article discusses the critical role of immunoglobulins in the immune system and the consequences of their deficiency, which can lead to recurrent infections and other serious health issues [1] - A live session featuring Professor He Jing from Peking University People's Hospital will provide insights on identifying, diagnosing, and managing immunoglobulin deficiency [1] Group 1: Health Implications - Immunoglobulin deficiency can result in frequent respiratory infections, difficult-to-treat diarrhea, organ abscesses, and autoimmune diseases [1] - This condition is often misdiagnosed as general poor health, leading to delays in treatment [1] Group 2: Expert Profile - Professor He Jing is a leading expert in rheumatology and immunology, holding multiple prestigious academic positions and recognized as a national leader in scientific innovation [2] Group 3: Live Session Details - The live session will take place on October 10 from 15:00 to 16:00, focusing on health education regarding immunoglobulin deficiency [1] - Viewers can access the session through the People's Good Doctor App or by following the People's Health public WeChat account [3]
