Shenyang, June 27th (Xinhua) - Recently, many parts of the country have been experiencing high temperatures, with some areas reaching a maximum temperature of 43 degrees Celsius or above. The heatwave is raging, and the number of patients seeking treatment for heatstroke in the hospital is constantly increasing. What to do with outdoor heatstroke? Can you pour a cold drink too hard if you're too thirsty? Can you quickly take a cold shower and cool down when coming home from outside? The reporter recently interviewed multiple experts to interpret the hot topics of public concern.
Recently, the first aid team of the Huanggu Third Branch of Shenyang Emergency Center received a call from the 120 Command Center: In Beiling Park, a middle-aged man suddenly experienced symptoms such as sweating, dizziness, and headache. After preliminary consultation, the visiting doctor determined that the patient had a premonitory heat stroke. After timely treatment, the patient's condition has significantly improved.
"According to the severity of the illness, heatstroke can be divided into premonitory heatstroke, mild heatstroke, moderate heatstroke and severe heatstroke. Severe heatstroke is what we call heat stroke. When patients have experience of working in high temperature environment or high-intensity physical activity, and have symptoms such as high fever and disturbance of consciousness, labor type heat stroke is generally considered first." Kong Lingjuan, a physician at the third branch of the Huanggu Center of Shenyang Emergency Center, said that under high temperature, infants and older people over 65, people who are overweight or have chronic diseases such as diabetes and cardiovascular diseases, and people who engage in strenuous activities in high temperature weather are vulnerable to heatstroke, they should pay special attention to sunstroke.
"Prolonged exposure to high temperatures can lead to symptoms such as headaches, dizziness, and thirst. If the symptoms are severe, they may also be accompanied by flushing, burning skin, and damp and cold limbs. Failure to intervene in a timely manner can gradually develop into coma, limb convulsions, and in severe cases, multiple organ failure." said Liu Hongdan, Director of the Emergency Department of Shenyang Tenth People's Hospital.
How should emergency measures be taken for people who have already developed symptoms of heatstroke? Experts suggest taking three steps in a timely manner. One is to quickly evacuate heatstroke sufferers from the high temperature environment, transfer them to a well ventilated and cool place, lie flat, and remove clothing; The second is to quickly cool down, spray with cold water or wipe the whole body with a wet towel, which can accelerate evaporation and convective heat dissipation by fanning; The third is to continuously monitor body temperature, urgently call 120, and send to the hospital.
Although "coolness" is an urgent need for people in high temperatures, experts suggest that no matter how thirsty you are, you should not drink cold drinks forcefully, and it is not advisable to take a cold shower directly to cool down.
In summer, the blood vessels in the human body are in a dilated state. After vigorous exercise, suddenly drinking a large amount of cold drinks or immediately blowing air conditioning or taking cold showers may cause immediate constriction and spasms of the blood vessels throughout the body, sudden increase in blood pressure and viscosity, leading to vascular blockage, angina pectoris, and myocardial infarction.
Liu Bo, Deputy Chief Physician of the Nutrition and Food Hygiene Institute of the Shenyang Center for Disease Control and Prevention, pointed out that excessive sweating in a high-temperature environment not only causes water loss, but also accompanies a large amount of electrolyte loss. It is necessary to drink water in moderation to maintain normal hydration of the body. You cannot wait until you are thirsty before drinking water. It is important to replenish water in a timely manner. In addition, it is necessary to mix water and appropriate concentrations of sodium and other electrolytes to maintain metabolism and acid-base balance in the body. Drinks containing electrolytes can be supplemented appropriately.
When sweating profusely, you can use a towel to dry the sweat before taking a shower. If it is necessary to take a cold shower, it is best to first rinse the limbs with cold water, wait for the body to adapt, and then rinse the whole body.
