中新健康丨专家紧急提醒，大降温这类人别“硬抗”

Core Viewpoint - The article discusses the health risks associated with sudden temperature drops in autumn, particularly for cardiovascular disease patients, and provides recommendations for maintaining heart health during this season [2][3][11]. Group 1: Health Risks from Temperature Drops - Sudden temperature drops can lead to increased cardiovascular disease incidents due to factors such as blood vessel contraction, increased blood viscosity, and emotional stress [3][4][6]. - The phenomenon of "thermal expansion and contraction" in blood vessels can elevate blood pressure and increase the risk of heart attacks [3]. - Dry autumn air can lead to thicker blood, which slows circulation and promotes blood clot formation [4]. Group 2: Recommendations for Cardiovascular Patients - Patients with cardiovascular diseases should avoid extreme temperature exposure and adjust clothing based on their comfort level, especially as temperatures drop [8][10]. - Key body parts such as the head, neck, abdomen, and feet should be kept warm to prevent cold-related health issues [9]. - A layered clothing approach is recommended, with thicker clothing on the lower body to maintain warmth [10]. Group 3: Heart Health Maintenance Tips - Maintain a balanced diet with low salt, oil, and sugar, while ensuring dietary variety [11]. - Engage in moderate exercise, adapting to indoor activities when outdoor temperatures are low [11]. - Stay hydrated by drinking water regularly, not just when thirsty, to avoid increasing heart strain [11]. - Regularly monitor health indicators such as blood pressure and blood sugar levels [11]. Group 4: Emergency Response for Cardiac Events - Recognize symptoms of potential cardiac events, such as chest pain or shortness of breath, and take immediate action [12][13]. - If symptoms persist, seek emergency medical assistance promptly [14].
