After the autumnal equinox, the temperature difference between day and night increases, and cardiovascular diseases enter a high-risk period. Experts suggest that the key to protection lies in taking scientific measures to address temperature differences. Wang Jian'an, chief physician of the Department of Cardiology at the Second Affiliated Hospital of Zhejiang University School of Medicine, said that when the temperature drops sharply, the human body contracts blood vessels in order to maintain body temperature, leading to an increase in blood pressure and an increase in cardiac load. For individuals with pre-existing cardiovascular diseases, blood pressure fluctuations significantly increase the risk of developing conditions such as angina and myocardial infarction. ”Ma Wenjun, Chief Physician of the Hypertension Ward at Fuwai Hospital, Chinese Academy of Medical Sciences, gave a special reminder. How to scientifically protect? Ma Wenjun said that the key to protection is to cope with temperature differences. Onion style clothing can be adopted to keep warm dynamically, especially to protect the head, neck, back, feet and other parts that are prone to catching cold. Patients who usually take antihypertensive drugs should pay attention to regular medication and strengthen morning blood pressure measurement. Once blood pressure continues to rise or fluctuates too much, they should consult a doctor in a timely manner and adjust the medication plan scientifically. In addition, experts suggest that outdoor exercise can be carried out at a suitable time of the day, with sufficient warm-up before exercise to allow the cardiovascular system to have a sufficient "start-up and adaptation" process. The intensity of exercise should be slightly warm and not cause excessive sweating, avoiding exposure to the wind after exercise. (New Society)
