【A reminder to you】
Recently, there have been hot weather in many places.
In hospital admissions, the number of patients with heat stroke and heat stroke due to prolonged outdoor exercise has increased.
Experts point out that it is not advisable to blindly pursue "Summer training" in the hot summer season.
Han Xiaotong, an expert in the emergency department of Hunan Provincial People's Hospital, introduced that heat stroke, also known as severe heatstroke, is a fatal emergency, mainly characterized by high fever and disturbance of consciousness. The patient's body temperature regulation function is dysfunctional due to high temperature, resulting in organ damage and even organ failure. .
For young students, do not blindly engage in outdoor sports in hot weather, but choose slow-paced sports such as swimming, aerobics, and Tai Chi.
If you sweat a lot, you should replenish water in time. If necessary, you can drink light salt water or salt-containing beverages to ensure the electrolyte balance in the body.
Zhang Xingwen, an emergency doctor at Hunan Provincial People's Hospital, suggested that sports enthusiasts can choose to exercise outdoors in the early morning or evening.
In 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, so as to avoid excessive sweating, high body temperature and heat stroke.
Don’t take a bath immediately after exercising, let alone eat cold drinks or take a cold shower. If you take a cold bath after sweating, it will close the pores and constrict blood vessels, which will make you more likely to get sick.
Han Xiaotong reminded that sports enthusiasts can carry common medicines such as Huoxiangzhengqi liquid and Fengyoujing when exercising outdoors. If symptoms of heatstroke occur, they can take some Huoxiangzhengqi liquid and perform physical cooling at the same time; pay attention to ventilation and cooling when exercising indoors , Families using air conditioners need to adjust the temperature to a suitable temperature, not too low, so as not to reduce the heat resistance of people, and it is difficult to adapt when going out.
Professor Pan Gang, an expert in cardiovascular disease in Hunan, reminded that in summer, people are prone to dehydration when they sweat a lot after exercising, which reduces circulating blood volume. In addition, high temperature will also dilate blood vessels and reduce blood return to the heart, which may lead to blood pressure. Significantly lower, 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 viscous, which will easily induce thrombosis, and induce dangerous conditions such as myocardial ischemia and myocardial infarction.
The elderly and patients with cardiovascular disease should exercise according to their ability, and should avoid exercising in the hot sun and walking for a long time to avoid cardiovascular accidents.
