Recently released a high temperature warning signal.

Meteorology calls the weather above 35℃ high temperature weather.

Beijing: On May 26th, all the urban areas in Beijing broke through the high temperature line of 35℃. On 16, Beijing Meteorological Observatory announced that the highest temperature near Tiananmen Square reached 39℃. 14 or so, an electronic display screen on Badaling Expressway also showed a high temperature of 39℃.

Shandong: The weather forecast released by Shandong Meteorological Observatory on 27th 1 1 said that in the next 24 hours, there will be high temperature above 35 degrees Celsius in many cities in Shandong Province. Heze City has issued an orange signal for high temperature warning.

How to deal with high temperature

First, replenish water in time but drink less drinks. Juice, cola, sprite, soda and other drinks contain more saccharin and electrolyte. Drinking too much will cause bad stimulation to the gastrointestinal tract and affect digestion and appetite. So drink more boiled water or light salt (sugar) boiled water in summer. It is not advisable to binge drink after thirst. After sweating a lot in labor and sports, it is not advisable to drink a lot of white water, and some light salt (sugar) water should be supplemented appropriately, because after sweating a lot, too much salt is lost in the human body, accounting for about 0.5% of sweat. If salt is not supplemented in time, the ratio of water to salt in the body will be seriously unbalanced, leading to metabolic disorder.

Second, avoid "sudden cooling" after heating. In hot summer, when people go out or come back from work, they like to either turn on the electric fan or take a cold bath immediately, which will make the pores of the whole body close quickly, but the heat in the body is difficult to dissipate, and it will also cause insufficient blood supply to the brain due to the rapid contraction of blood vessels in the brain, which makes people dizzy.

3. The strongest time of solar short-wave radiation is around 10-15. Try to avoid going out during this time, and apply some sunscreen skin care products to your skin. It is best to wear light clothes in summer.

Fourth, the temperature difference between indoor and outdoor air conditioners should not be too large. The temperature difference between indoor and outdoor air conditioners should not exceed 5 degrees. Even if the weather is hot again, the indoor temperature of the air conditioner should not be lower than 24 degrees.

Fifth, the diet should not be too light. In summer, people have long activities, sweat a lot and consume a lot. They should eat more nutritious foods such as chicken, duck, lean meat and fish eggs to meet the metabolic needs of the human body.

Sixth, the nap time should not be too long. If the nap time is too long, the central nervous system will deepen the inhibition, the cerebral blood flow will be relatively reduced, and the metabolic process will slow down, leading to discomfort after waking up and more sleepiness.
