What is the temperature in summer?
35℃ is considered as high temperature. In China's meteorology, when the daily maximum temperature reaches or exceeds 35℃, it is generally called high temperature. Hot weather will make people feel uncomfortable, reduce work efficiency and increase the incidence of heatstroke, intestinal diseases and cardiovascular and cerebrovascular diseases. At the same time, high temperature weather will also have a greater impact on agricultural production.
High temperature warning: high temperature yellow warning signal: the temperature reaches 35℃ for three consecutive days; High temperature orange warning signal: the temperature reached 37℃ that day; High temperature in red warning signal: The temperature reached 40℃ that day.
High temperature and heat wave make the human body unable to adapt to the environment and exceed the tolerance limit of the human body, leading to the occurrence or aggravation of diseases and even death, and so do animals; At the same time, high temperature and heat wave will also affect the growth and development of plants and reduce crop yield. The high temperature heat wave process will also aggravate the occurrence and development of drought; The rapid increase of water consumption and electricity consumption has a great impact on people's life and production. In addition, high-temperature heat waves often make people fidgety and even lose their minds, which easily leads to public disorder, accidents, casualties, poisoning, fires and other events, which are indirect effects of high-temperature heat waves.
Prevention methods of high temperature weather
The high temperature of 34℃ is a threshold. In daily life, whether it is cold or hot, it will cause physical discomfort. People's normal body temperature is maintained at around 37℃. According to international experiments, the comfortable temperature of human body is 19℃~24℃ in summer and 12℃~22℃ in winter. Therefore, in the hot summer, when the humidity is high and the temperature reaches 34℃, people need to pay attention. When the temperature and humidity reach a certain limit, the human body's heat cannot be dissipated, and the body temperature will rise, exceeding the human body's tolerance limit, causing fatal accidents.
In hot weather, people will experience a lot of sweating, which is very easy to get heatstroke or collapse. Old, weak, sick and young people should reduce outdoor activities and pay attention to drink plenty of water to replenish body moisture. When the weather is hot, a lot of sodium and potassium in the human body are lost with the discharge of sweat, which can cause electrolyte imbalance; The loss of vitamin C, vitamin B 1 and vitamin B2 in human body with sweat can cause nutrient metabolism disorder. The increase of protein decomposition in human body will cause the increase of energy consumption. Therefore, it is very important to ensure the nutritional needs and reasonable diet of human body in high temperature weather for maintaining the physiological function, metabolic activity and electrolyte balance of the body, adapting to the high temperature working environment and living environment, and ensuring health. First of all, replenish water. When the temperature is 36℃ ~ 38℃ in summer, people engaged in outdoor manual labor should replenish water 10L ~ 12L every day. People who are engaged in indoor work should supplement 2L~3L ~ 3 L of water every day. Drinking less water should not be more, so as not to affect appetite. In addition, a lot of sweating will also lead to the loss of inorganic salts, so inorganic salts should be supplemented while hydrating. At the same time, we should pay attention to increasing the intake of vitamin C, protein and energy.
What should I pay attention to when driving in hot weather?
1, don't put dangerous goods in the car.
The ambient temperature in summer is already very high. If some inflammable and explosive articles such as mineral water, perfume, lighters and charging treasures are placed in the car, it is easy to cause safety hazards. In addition, don't put glass, crystal and other items that are easy to concentrate, otherwise the sunlight will be concentrated indoors, which will easily damage the room and even catch fire. Some spontaneous combustion accidents happen in this way, so you should clean up the dangerous goods in the car in time.
2, to prevent parts from producing high temperature
Some internal parts of automobiles are prone to generate heat, especially parts such as engines and gearboxes. Engine and gearbox are the most important parts of a car. If the ambient temperature is too high in summer, these parts will heat up, the working temperature inside the car will be too high, and even spontaneous combustion will occur. Therefore, it is inevitable to use good quality coolant and gearbox oil.
3. Check the car tires in time.
The temperature is too high in summer, but the road surface temperature may reach about twice. The only thing that the car touches the road is the tire. Every day, the hot road will be rubbed, which will lead to an increase in tire pressure. Of course, the chances of a flat tire and a rollover will also increase a lot.
Therefore, drivers should always check whether there are any problems such as wear, bulging and cracking of automobile tires, and the number of tire patching should not be too many. It is best to replace the tires that have been repaired many times. In addition, tire pressure monitoring equipment can be installed to pay attention to whether the tire pressure is normally maintained in the range of 2.3-2.8BAR.
4, the correct use of automobile air conditioning.
After a day of exposure, the temperature inside the car is already very high, and many old drivers turn on the air conditioner as soon as they get on the bus, which is definitely wrong. The correct way is to open the doors and windows to cool the interior space of the car, and then drive for a while before turning on the air conditioning fan.
Don't adjust the temperature very low while driving. In addition to increasing fuel consumption, it is not good for your health. The air conditioner should be turned off in advance, preferably when it is a kilometer or a few minutes' drive from the destination. The practice of turning off the air conditioner after flameout will easily affect the service life of the engine.
