Xinhua News Agency, Changsha, June 30 (Reporter Shuai Cai) Recently, hot weather appeared in many places. In the hospital, the number of patients with heatstroke and heatstroke increased due to long outdoor exercise time. Experts pointed out that it is not advisable to blindly pursue "three volts in summer" during the hot summer season.
Han Xiaotong, an expert in the emergency department of Hunan Provincial People’s Hospital, said that heat stroke, also known as severe heatstroke, is a fatal emergency, characterized by high fever and disturbance of consciousness. Patients suffer from abnormal thermoregulation due to high temperature, resulting in organ damage and even organ failure. For young students, outdoor sports should not be blindly carried out in hot weather, and slow-paced sports such as swimming, aerobics and Tai Ji Chuan can be chosen. If you sweat a lot, you should replenish water in time, and if necessary, you can drink light salt water or salty drinks to ensure the electrolyte balance in your body.
Zhang Xingwen, an emergency doctor at Hunan Provincial People’s Hospital, suggested that sports enthusiasts can choose to do outdoor sports in the early morning or at dusk. During the hot summer season, sports enthusiasts should not exercise for too long every day. Generally, it is advisable to exercise for 30 minutes to 1 hour to avoid excessive sweating and high body temperature, which may cause heatstroke. Don’t take a bath immediately after exercise, let alone eat cold drinks or take a cold bath. If you take a bath with cold water after sweating, your pores will close and your blood vessels will contract, but you will easily get sick.
Han Xiaotong reminded that sports enthusiasts can carry common medicines such as Huoxiang Zhengqi Liquid and Fengyoujing when exercising outdoors. If heatstroke symptoms occur, they can take some Huoxiang Zhengqi Liquid and physically cool down at the same time; Attention should be paid to ventilation and cooling when exercising indoors. Families using air conditioners need to adjust the temperature to a suitable level, not too low, so as not to reduce people’s heat resistance and make it difficult to adapt when going out.
Professor Pan Gang, an expert on cardiovascular diseases in Hunan, reminded that in summer, people are prone to dehydration when sweating heavily after physical exercise, thus reducing the circulating blood volume. In addition, high temperature will also dilate blood vessels and reduce the blood volume, which may lead to a significant decrease in blood pressure, causing collapse, fatigue and even fainting. In addition, after a large amount of water is lost, if it is not replenished in time, the blood will become relatively thick, which will easily induce thrombosis and induce dangerous situations such as myocardial ischemia and myocardial infarction. The elderly and patients with cardiovascular diseases should exercise according to their abilities, and should avoid exercising in the scorching sun and walking for a long time to avoid cardiovascular accidents.
