Summer in Wuhan is too hot. Is there any way to cool off the heat?

Five measures to prevent heatstroke 1. Wear light-colored clothes: When traveling in summer, you should wear white, light-colored or plain clothes, not black or blue clothes, because white, light-colored or plain clothes absorb heat slowly and dissipate heat quickly, and wearing cool clothes is not easy to get heatstroke; Black or blue clothes absorb heat quickly, dissipate heat slowly, and are sultry and prone to heatstroke. 2. Wear an insulated straw hat: The raw materials for weaving straw hats are mostly hollow, which stores a certain amount of air and is a bad conductor of heat. In addition, the straw hat has a certain shielding effect on the sun. So it's best to wear a straw hat when traveling in summer. 3. Rest at noon: The air is fresh and the climate is cool in the morning. Therefore, if you travel in summer, you should start early, rest at noon and travel after three or four in the afternoon. In this way, when traveling, you will not only be energetic, but also feel tired and heatstroke. 4, drink more salt water: the summer temperature is high, sweating is more, the salt in the body is reduced, and the osmotic pressure in the body will lose balance, leading to heatstroke. Drinking more salt, boiled water or salt water can replenish the salt lost in the body, thus preventing heatstroke. When drinking salt water, you need to drink a small amount of salt water many times to prevent heatstroke. 5, with heatstroke prevention drugs: during the trip, it is easy to encounter a changeable climate, cold and hot temperatures are easy to catch a cold, and sultry weather is the most prone to heatstroke. Therefore, when traveling in summer, you should take some heatstroke prevention drugs, such as Ren Dan, cooling oil, tiger balm, wind oil, ten drops of water, and Huoxiang Zhengqi water. Once heatstroke occurs, the patient should be carried to a cool and ventilated place to lie down and rest, then the patient's clothes should be unbuttoned, and a cold water towel should be applied to the patient's head and neck, so that the patient can take some pills or ten drops of water. If the patient faints, you can pinch the patient's Renzhong point with your fingers or acupuncture Xuan Shi point with your fingertips. When the patient gets better, he will be sent to a nearby hospital for treatment. Summer heatstroke prevention is "treasure"? In the hot summer, the heat is unbearable. People often regard fruit juice, sorbet and other cold drinks and snacks as treasures to relieve summer heat and cool down. In fact, the treasures of heatstroke prevention and cooling in summer should be the following: salty boiled water: Chinese medicine says that "boiled water is the king of all medicines." From the point of view of nutrition, any sugary drink is not as valuable as boiled water, because pure boiled water can be quickly absorbed by the stomach after entering the human body, enter the blood circulation to play the role of metabolism, and at the same time regulate body temperature and clean the internal environment of the human body. When drinking boiled water, you should choose fresh cold boiled water (20-25℃) that naturally cools after boiling. This kind of boiled water has specific biological activity, and it is easy to enter cells through the cell membrane and be quickly absorbed and utilized. You'd better add some salt when drinking boiled water. In summer, the temperature is high, sweating is much, the salt in the body is reduced, and the osmotic pressure in the body will lose stability, leading to heatstroke. Drinking salty boiled water or salty tea can supplement the salt lost in the body, thus achieving the effect of heatstroke prevention and cooling. Tea: Experienced health care doctors often instruct people to supplement potassium by drinking tea. Potassium is an important trace element in human body, which can maintain the normal function of nerves and muscles, especially the normal movement of myocardium. If potassium is lacking, people will feel tired and weak, and their heat resistance will be reduced. Severe potassium deficiency can lead to arrhythmia and muscle weakness. Scientific analysis shows that tea contains more potassium, accounting for about 1.5% of its proportion. Potassium is easily excreted with sweat, so tea with suitable temperature should be the first choice in summer. Vinegar: In summer, people drink more water, so their stomach acid decreases correspondingly and their appetite decreases. Proper vinegar can increase the concentration of gastric acid, stimulate appetite and help digestion. Adding vinegar when cooking can increase stomach acid and increase appetite. Summer is the epidemic season of intestinal infectious diseases, and jealousy can also improve the bactericidal effect of gastrointestinal tract. In addition, if a few drops of vinegar are added during cooking, the loss of vitamin C in vegetables will be reduced, which is beneficial to the absorption of iron in food.

In fact, the most appetizing and refreshing melon food in theory is bitter gourd. Bitter gourd is fragrant and delicious because of its bitter taste, and it is regarded as a rare dietotherapy product. China folks have had the experience of "bitter can clear away heat" and "bitter can strengthen the stomach" since ancient times. Especially in hot summer, people should eliminate summer heat and relieve fatigue. Chinese medicine believes that bitter gourd tastes bitter and cold, and can clear away heat and purge fire.

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. Second, it is not advisable to binge drink after being thirsty. 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 you drink a lot of white wine, it will contribute to dryness and dampness, which is tantamount to adding fuel to the fire. 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. 7. Avoid "rapid 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. Eight, air conditioning indoor and outdoor temperature difference should not be too big. 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. Nine, it is not appropriate to wear metal jewelry. Some metals in metal ornaments are stained with sweat, and the skin will be red or itchy when worn, which may easily lead to contact dermatitis. How to use summer medicine in midsummer?
