How to protect yourself on a ＂barbecue＂ day when the temperature in more than 30 places in China has broken the historical extreme value？

　　Xinhua News Agency, Beijing, July 13th (Reporter Deng Huaning, Wang Bin) According to the information released by the Central Meteorological Observatory, the temperature in more than 30 areas of the country has recently exceeded the historical extreme, and Turpan, Xinjiang even exceeded 49 degrees Celsius. On the 12th, the country entered a 40-day "three volts". What impact will the "barbecue" day with long time, wide coverage and high intensity have on people’s lives? How to deal with it? The reporter recently interviewed an environmental and health expert from China Center for Disease Control and Prevention.

　　Experts said that continuous high temperature or heat wave makes people feel uncomfortable, and the main impact on human health is heatstroke, which leads to indigestion, increased incidence of gastrointestinal diseases, arthritis, cardiovascular and cerebrovascular diseases, and even death. But as long as the corresponding protection is done, the damage of high temperature can be avoided.

　　First of all, the general population needs to pay attention to five aspects:

　　Get and understand the forecast and early warning information of high temperature and heat wave in time. The public can check the weather forecast through the Central Meteorological Observatory or China Weather Network, or through radio, mobile phones, newspapers and other channels, arrange their work and life reasonably and take corresponding protective measures;

　　In the hot and hot weather, you should try to avoid traveling from 10 am to 4 pm, and pay special attention not to exercise under the strong sunlight, such as brisk walking and running.

　　Necessary protective measures should be taken during outdoor activities, including wearing breathable and light-colored clothes, which is helpful for heat dissipation; If you are outdoors for a long time, it is recommended to wear long-sleeved shirts; Wear sunglasses, use an umbrella, or wear a sun hat; For exposed skin, sunscreen can be applied to avoid solar dermatitis or sunburn;

　　Due to the high temperature weather, the body temperature will rise, and it is easy to cause heatstroke due to lack of water. Attention should be paid to timely hydration, but excessive drinking water will make the stomach difficult to adapt;

　　No matter when using air conditioning in the room or in the car, don’t set the temperature too low and the temperature difference between inside and outside should not be too large; It is best not to turn on the air conditioner immediately when the car stops in the hot sun. You should open the window to let the hot air out, and then turn on the air conditioner after the temperature inside the car drops. No matter in the room or in the car, it is best not to sleep with the air conditioner on, especially in the stopped car, where the ventilation is poor, and the carbon monoxide emitted by the engine leaks into the car, which will make people poisoned.

　　For the elderly, infants, pregnant women and vulnerable people such as patients with hypertension, coronary heart disease and cerebrovascular sclerosis, we need to pay attention to the following aspects:

　　In hot weather, vulnerable people such as the elderly, infants, pregnant women and patients with hypertension, coronary heart disease and cerebrovascular sclerosis should avoid outdoor activities during periods of strong sunlight;

　　Patients with hypertension, coronary heart disease, cerebrovascular sclerosis, etc. should drink some water first when they get up in the morning to replenish the water consumed overnight, reduce blood viscosity and promote blood circulation;

　　Patients with chronic diseases such as coronary heart disease, hypertension and arteriosclerosis, especially the elderly and patients with joint pain, should not stay in rooms with low air conditioning temperature for a long time. The indoor and outdoor temperature difference of vulnerable people should not exceed 5℃. It should not be too long to turn on the air conditioner, and it is best to turn it on in 1-mdash; Shut down after 3 hours and conduct natural ventilation. It is best to turn off the air conditioner before going to bed at night.

　　In addition, outdoor workers should attach great importance to protection:

　　People engaged in outdoor work in high temperature weather should arrange their working hours reasonably, rotate their work, appropriately increase the rest time of workers in high temperature working environment, reduce labor intensity, slow down and reduce outdoor work in high temperature period. In addition, it is necessary to take effective protective measures and carry heatstroke prevention products with you;

　　The operation time shall be adjusted according to the forecast temperature released by the meteorological station of the competent meteorological department at or above the municipal level on the same day;

　　Outdoor workers can wipe their bodies with ice towels to physically cool down;

　　After returning indoors from the outside, don’t turn on the air conditioner immediately to avoid catching a cold;

　　Outdoor workers should pay attention to dizziness, nausea, dry mouth, confusion, chest tightness, shortness of breath and other symptoms, should immediately rest, drink some cold water to cool down, serious illness should immediately go to the hospital for treatment.
