How to prevent heatstroke and cool down in dog days

1. Not to drink too much after thirsty: after a lot of sweating in labor and sports, it is not suitable to drink a lot of white water, and some light salt (sugar) water should be added appropriately, because a lot of sweating causes the loss of too much salt in the human body, if the salt is not added in time, the proportion of water and salt in the body will be seriously imbalanced, leading to metabolic disorder.

2. Do not drink too much: the human body is easily affected by the temperature in summer to accumulate damp and heat, and excessive damp and heat is the cause of skin ulcers, carbuncle and swollen poison. If you drink a lot of white wine, it will help the heat generate dampness, just like adding fuel to the fire.

3. Standing heatstroke medicine: it's hot in midsummer, hot and dry, which often makes people eat tasteless and sleepless. It's easy to have dizziness, headache, fatigue, even nausea, vomiting and other symptoms. In order to spend the summer safely, the family should prepare some heatstroke medicine. Common medicine and food are: ten drops of water, Huoxiang Zhengqi water, cool oil, honeysuckle, chrysanthemum, lotus leaf, watermelon.

4. Learn to take a good nap: in summer, the days are long and the nights are short, the weather is sultry, the sleep time is short, and the sleep quality is poor. If you can take a nap in the afternoon, it's like recharging your brain, which is conducive to physical recovery.

5. Humidity exercise: 'life lies in exercise', but people who are old, weak and lack of exercise at ordinary times should never exercise violently, otherwise it will be harmful and useless. According to the world consensus, the best sport is walking.

6. Hot tea is better than cold drink: medical research shows that hot tea is better than cold drink in heatstroke prevention and cooling, and it lasts longer. Tea is rich in potassium. The increase of sweating in summer often causes excessive loss of potassium ions. Potassium and sodium jointly maintain the normal osmotic pressure and acid-base balance inside and outside the cells, which has an important influence on the function of nerves and muscles, especially the normal movement of the heart muscle. When the potassium in the body is insufficient, the body often feels tired and weak, appetite drops, heat resistance drops, and even heatstroke. In summer, drinking tea often can supplement potassium element of human body, improve heat resistance and effectively prevent heatstroke.

Analysis of climate and temperature in the dog days

First of all, as the surface humidity increases after the fall, the heat absorbed by the ground every day is more, the heat emitted is less, and the heat of the surface layer accumulates, so it gets hotter day by day. Entering the middle voltage, the heat accumulated on the ground reaches the highest value, and the weather is the hottest.

In addition, there is more rain in summer, and the air humidity is large. The heat capacity of water is much larger than that of dry air, which is also an important reason for the sultry weather in three rainy days. In July and August, the subtropical high pressure was strengthened. Under the control of the subtropical high, the downdraft inside the high pressure made the weather clear and cloudless, which was conducive to the sunshine, the ground radiation increased temperature, and the weather was even hotter.

After entering the final days, the weather is gradually cool. It's cooler in the morning and evening. It's still hot at noon. Each area will be different. Because the last fall is after the beginning of autumn, even the so-called "autumn tiger" is hot in the daytime and cool in the morning and evening.
