The key measures to prevent heatstroke and cool down in a prolonged battle against high temperatures should be kept in mind! Weather | salinity | high temperature
Beijing, June 22 (Xinhua) - According to the prediction of the Central Meteorological Observatory, from June 21 to 28, there will be sustained high temperatures in North China. It is expected that regions such as Beijing, central and southern Hebei, and Tianjin will experience high temperatures ranging from 35 ℃ to 37 ℃, with local highest temperatures possibly reaching 39 ℃ to 40 ℃.
Affected by the high temperature weather, the number of heatstroke patients received by medical institutions has significantly increased, and some people have even died from heatstroke. What is heat stroke? How to prevent heatstroke and cool down in hot weather? What should I do if I experience heatstroke? The reporter interviewed relevant medical experts.
What is heat stroke? What is the difference between heatstroke and heat stroke?
According to Teng Fei, Deputy Chief Physician of the Emergency Department at Beijing Chaoyang Hospital, heatstroke can be divided into premonitory heatstroke, mild heatstroke, and severe heatstroke based on clinical manifestations. Severe heatstroke can be further divided into heat spasms, heat exhaustion, and heat stroke.
Heat stroke, also known as the most severe type of heat stroke, is a severe clinical syndrome caused by exposure to high temperature and humidity environments that rapidly increase the core temperature of the body, accompanied by multiple organ system damage such as skin burning and consciousness disorders.
Tengfei said that the incidence of heat stroke is closely related to three environmental factors, namely high temperature, high humidity, and no wind environment. Its typical clinical manifestations include high fever, no sweating, and coma, which may be accompanied by systemic epileptic seizures, rhabdomyolysis, and multiple organ dysfunction syndrome.
Which groups of people need attention? What should I pay attention to when going out?
The "Guidelines for Public Health Protection against High Temperature Heat Waves" released by the National Bureau of Disease Control and Prevention indicate that there are mainly three types of key populations for high temperature heat wave protection. The first type is sensitive populations, such as children, pregnant women, and the elderly; The second group is patients with chronic basic diseases, such as circulatory diseases, respiratory diseases, mental and behavioral disorders, kidney diseases and diabetes; The third category is outdoor workers, such as farmers, construction workers, sanitation workers, couriers, etc.
Lin Ying, Deputy Chief Physician of the Occupational Health Institute of the Beijing Center for Disease Control and Prevention, said that the schedule should be adjusted according to the high temperature weather, and outdoor activities should be avoided during the highest temperature period of the day. Take necessary sun protection measures when going out, try to wear sunglasses, sun hats, or umbrellas, and wear breathable and heat dissipating cotton, linen, and other fabrics.
What to do with heatstroke? Can I blow the air conditioning and take a cold shower?
The National Bureau of Disease Control and Prevention reminds that high temperature heatwaves can exacerbate the occurrence and development of circulatory, respiratory, urinary, and neurological diseases, causing attacks of cardiovascular and cerebrovascular diseases such as heart disease and stroke, leading to serious lung diseases, acute decline in renal function, and in severe cases, renal failure; It can also cause mental and behavioral disorders, leading to a series of mental disorders such as cognitive impairment, anxiety, and depression, thereby increasing the number of accidents and casualties.
Experts suggest that once someone suffers from heatstroke in the surrounding area, the patient should be immediately moved to a shady and cool place, and ventilation should be maintained; Unbutton your clothes and use various methods to help your body dissipate heat. You can take appropriate antipyretic drugs such as Huoxiang Zhengqi, and try pressing the middle acupoint to help restore consciousness. If the symptoms do not improve, you should immediately call the rescue hotline.
Lin Ying said that some people like to turn on the air conditioner, fan, or take a cold shower immediately after escaping from a high-temperature environment. However, this can cause the pores of the whole body to quickly close, making it difficult to dissipate heat in the body. It can also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain.
What should I pay attention to in my diet?
Lin Ying said that it is advisable to drink plenty of water in hot weather, but it is not advisable to drink excessively after thirst. It is advisable to supplement with some light salt water, as excessive salt loss in the body after sweating can lead to electrolyte imbalance and metabolic disorders if not replenished in a timely manner.
You can add some warm water, mung bean soup, or electrolyte containing beverages appropriately. Eat less high-fat foods and try to have a light diet. Difficult to digest foods can bring extra burden to the body. Adequate protein intake should be ensured, and fruits and vegetables can be eaten more, but it is not advisable to overeat cold drinks.
