多穿点防感冒？感冒从来不是“冻”出来的！

Core Viewpoint - The article discusses the misconception that cold weather directly causes colds, emphasizing that colds are caused by viruses transmitted through droplets or contact, not by cold temperatures [1][2]. Group 1: Understanding Colds - Cold weather can make the respiratory mucosa more sensitive, leading to a higher susceptibility to viruses and bacteria [2]. - Colds are generally self-limiting, with a typical duration of about 7 days, although some cases may last up to 2 weeks [4]. - Complications from colds can range from mild upper respiratory discomfort to severe conditions like pneumonia, myocarditis, and encephalitis [5]. Group 2: Symptoms and When to Seek Medical Attention - Symptoms such as persistent high fever (over 39°C) for more than 3 days, difficulty breathing, chest pain, or altered consciousness warrant immediate medical attention [8][9]. - If symptoms persist for over 10 days without improvement or worsen, medical advice should be sought, especially for vulnerable populations like children, the elderly, pregnant women, and those with chronic illnesses [10]. Group 3: Misconceptions and Treatment - Common misconceptions include the belief that excessive sweating can reduce fever and the misuse of antibiotics for viral infections, which are ineffective against colds [10][11]. - Traditional Chinese medicine should be used appropriately, as incorrect usage can exacerbate symptoms [11]. Group 4: Prevention Strategies - Preventive measures include maintaining a balanced diet, regular exercise, adequate sleep, and avoiding close contact with infected individuals [12][13]. - During cold seasons, wearing masks and ensuring proper ventilation indoors can help reduce the risk of infection [14].
