Expert Introduces Summer Heatstroke Prevention Methods
Symptoms such as chest tightness, dizziness, and pale skin can all be early signs of heatstroke. The public is reminded not to ignore these minor symptoms.
To avoid heatstroke, try to minimize outdoor activities during high temperatures, and avoid prolonged activities and walking in high-temperature, high-humidity environments, especially prolonged exposure to direct sunlight. Patients with cardiovascular, liver, kidney and other diseases, as well as the elderly, weak, and children, should try to reduce their time in high-temperature environments. In summer, wear loose, breathable clothing, and carry necessary sun protection tools to avoid direct sunlight. Rest promptly if you feel unwell. At the same time, arrange your schedule reasonably, ensure adequate sleep, and take an appropriate nap of about an hour and a half.
Meteorological Experts Offer Tips on Preventing Heatstroke
Experts from the Central Meteorological Observatory suggest that heatstroke is caused by a combination of factors and generally falls into two categories. One is high temperature and high radiation, commonly known as dry heat, where intense sun exposure and high temperatures cause the body to lose a large amount of water. If water is not replenished in time, it is very easy to suffer from heatstroke.
The other is high temperature and high humidity, that is, the common hot and humid weather in summer, where the body cannot sweat normally. Skin blood flow and cardiac output increase significantly, and the incidence of heart failure and mortality from heart disease also increase.
Meteorological experts state that preventing heatstroke focuses on prevention. In terms of diet, first and foremost, attention should be paid to replenishing water. The human body loses more water in summer, so you should not wait until you are thirsty to drink, by which time the body is already in a state of dehydration. In addition, some trace elements in the body are lost with the evaporation of water, so it is advisable to drink some salt water appropriately.
In terms of food, sufficient protein should be supplemented, such as fish, meat, eggs, milk, and legumes. In addition, you should eat more fresh fruits and vegetables that can prevent heatstroke, such as tomatoes, watermelon, bitter melon, peaches, dark plums, and cucumbers. Regarding cold drinks, the colder you eat, the more likely you are to get heatstroke. This is because a short-term decrease in local body temperature can make the body unable to adapt, affecting the digestive system, which in turn affects the normal functioning of various systems.
When going out, do a good job of sun protection. Wear sunglasses, a sun hat, or use a sunshade, and wear breathable cotton or silk fabric clothes. When cycling for a long time under the scorching sun, it is best to wear long-sleeved shirts or use a shawl, and wear a sun hat. When engaging in long-term outdoor activities, prepare heatstroke prevention medicines, such as Huoxiang Zhengqi Liquid, Shidushui, and Rendan. From noon to 2 p.m., when the sun is strongest, try not to stay outdoors. If conditions permit, take an appropriate lunch break. The air conditioner temperature should not be set too low, as a large temperature difference between indoors and outdoors can also lead to heatstroke.
Once heatstroke symptoms appear, how should the public respond? Experts say that if you have symptoms such as dizziness, nausea, and palpitations, you are likely suffering from heatstroke. At this time, you should immediately stop what you are doing, find a cool place to sit and rest; at the same time, replenish water with small sips to avoid加重 the burden on the heart. Unbutton the collar, tie, belt, etc., to keep the surrounding area ventilated, and apply or take anti-heatstroke medicine; after a period of rest, if the symptoms do not decrease but increase, seek medical attention promptly.
In addition, if someone around you shows symptoms of heatstroke, you should immediately move the patient to a cool place and keep the surrounding area ventilated; unbutton their clothes and use various methods to help the body dissipate heat; help them take anti-heatstroke medicine, and press acupoints such as Renzhong (GV26) and Hukou (LI4) to help restore consciousness. If the symptoms do not alleviate, call for emergency help immediately.
Reduce Labor Intensity During High Temperatures
In response to the hottest period of the year, the labor security department reminds that when high-temperature weather occurs, employers should adjust their work and rest systems according to production characteristics and specific conditions, increase rest and reduce labor intensity to ensure safe production.
A person from the Tianjin Municipal Human Resources and Social Security Bureau introduced that research shows that when the temperature exceeds a certain range, the incidence of work-related injuries increases in either excessively cold or hot environments. According to relevant national notices, employers should formulate a high-temperature heatstroke emergency rescue plan based on their actual situation. For employees with diseases unsuitable for high-temperature and high-humidity work, employers should temporarily transfer them from such posts. If they cannot be transferred, they should strengthen heatstroke prevention measures for them during high-temperature and high-humidity weather.
Labor security experts explained that according to China's relevant laws and regulations, heatstroke at work in high temperatures is considered a work-related injury. When frontline workers suffer from heatstroke in a high-temperature environment, the worker or on-site personnel should immediately report to the employer; the employer should then report to the local labor security department within 24 hours and apply for a work-related injury determination. After being recognized as a work-related injury, the heatstroke-stricken employee can enjoy work-related injury benefits in accordance with relevant regulations. For employees who have participated in work injury insurance, medical expenses will be paid by the work injury insurance fund. If the employer has not participated in work injury insurance, the medical expenses should be borne by the enterprise. If the enterprise refuses to pay, the employee can complain to the labor security supervision department.
It is understood that during the treatment period for work-related injuries such as heatstroke, it is considered as normal labor, and the employer must pay wages and corresponding subsidies.
Labor security experts emphasize: in high-temperature weather, employers must especially increase protection for female employees and must not安排 pregnant female employees to work outdoors in temperatures above 35°C or in workplaces with temperatures above 33°C.
