Core Viewpoint - Recent weather changes in China, including strong winds, temperature drops, and snowfall, have raised health concerns for vulnerable populations [1][2]. Group 1: Vulnerable Populations - Specific groups requiring special attention during cold weather include the elderly, pregnant women, infants, individuals with cardiovascular diseases (such as hypertension, stroke, coronary heart disease), respiratory diseases, and those who work or engage in activities outdoors for extended periods [2]. Group 2: Health Risks Associated with Cold Weather - Cold weather can exacerbate cardiovascular diseases due to physiological responses like blood vessel constriction, increased blood pressure, and heart rate, which may lead to conditions such as hypertension, stroke, and myocardial infarction [3]. - Respiratory diseases may increase as cold air can dry out mucous membranes, making individuals more susceptible to infections and exacerbating conditions like asthma [4]. - Other health issues may arise for those living or working in cold environments, including frostbite and worsening of pre-existing conditions like joint pain and rheumatism, as well as potential adverse effects on pregnant women and fetuses [4]. Group 3: Protective Measures - Individuals should dress warmly, particularly protecting extremities like hands and face during sudden temperature drops [5]. - Ensure doors and windows are secured, and outdoor structures are reinforced [6]. - Caution is advised to prevent slips and falls when outside [7]. - Vulnerable groups should maintain warmth, enhance nutrition, engage in moderate exercise, and limit outdoor activities [7]. - Adequate rest is essential to avoid fatigue [8]. - Households using coal stoves should be vigilant against carbon monoxide poisoning [9]. - During windy conditions, be aware of potential falling objects [10]. - Stay informed about weather forecasts and cold wave alerts from relevant authorities [10].
