The hottest time in summer is Sanfu day. Sanfu day is divided into the first and the last, which is the hottest? Three dog days hot weather, bad appetite, how should we health? Let's get to know with Xiaobian.
What's the hottest day
The hottest stage of three dog days: Zhongfu
1. When it comes to which one of the three volt days is the hottest, we need to mention the folk saying "cold in Sanjiu, hot in Zhongfu", which means that the hottest day of the year belongs to the "three volt", and the "three volt" is the hottest. After the end of the day, the weather began to cool.
2. 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.
3. 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.
4. 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.
5. After entering the final days, the weather is gradually cool. It's cooler sooner or later. It's still hotter at noon. Each region 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.
What are the taboos in the dog days
Avoid exposure to the sun
On the one hand, sunburn, light aging, wrinkles and even skin cancer are the greater risks of exposure.
Ultraviolet rays in the sun can cause skin peeling, erythema, and even blisters. UVA in ultraviolet rays can penetrate glass, penetrate into dermis, destroy collagen and elastic fiber, make skin aging in advance, and even cause skin cancer.
In addition to the skin, strong sunlight can damage the eyes. If we don't do enough protection, UV may damage the lens, macula retina, cornea and other eye structures.
Avoid water shortage
Generally speaking, in order to maintain normal physiological function, each person needs about 1.5 liters per day. However, in the high temperature environment or after sports work, under the condition of sweating a lot, the daily water demand can increase to 2 to 16 liters!
Water is the source of life. When the body needs it, it must be satisfied. If there are kidney stones, gout, diabetes and other conditions, drinking more water can also achieve the role of prevention and treatment. But one thing is, when you are thirsty, don't drink water too fast, or your stomach will feel full and uncomfortable.
As for what water to drink, the most recommended one is always boiled water. Remember to replenish water in summer. Drink slowly to relieve summer heat.
Don't be greedy
This is not to say that you can't turn on the air conditioner, drink ice water, or eat ice cream, but that you should do something appropriate and comfortable according to your actual situation. Low temperature will not cause arthritis, but if there is arthritis, too low temperature will make the joints feel pain and discomfort.
Therefore, it is recommended that the indoor and outdoor temperature difference should not exceed 7 degrees, and it is more appropriate to set the air conditioning temperature at about 25 degrees, and it is better not to directly face the air conditioning to blow cold air. Many people are used to drinking hot water and are afraid to drink cold water. But in fact, our body is not so fragile. Drinking a few mouthfuls of ice water will not reduce the core temperature of our body. The so-called cold drink and ice cream will make you "cold" is just speculation, there is no definite evidence.
If you feel too cold and feel uncomfortable, don't eat. If you feel a little cold, you can relieve the heat and have fun. After eating and drinking, you won't feel uncomfortable. You can drink boldly without worry. But because of the high sugar content and energy of ice products, friends with hyperlipidemia and diabetes should not eat too much. In addition, you'd better rinse your mouth after eating the sweet ice food.
Avoid sedentary
When it's hot, people become lazier. Stay in the cool room, nest in the sofa, watch TV with watermelon in hand, and don't remember sitting.
The American Diabetes Association's 2016 guidelines make it clear that all people should reduce their sedentary time, especially avoid sitting for more than 90 minutes. Sedentary also easy to lead to leg swelling, lower extremity thrombosis, accelerated spine aging. Sedentary harm is big, had better get up every half hour activity.
Xiaobian suggests that you change a small cup to drink water. When you have finished drinking, you will get up to pick up the water. In this way, we can not only exercise our muscles and bones, but also drink more water and kill two birds with one stone. When the sun is not rising in the morning or the summer heat is dissipating at night, you can go out for a walk to exercise, or you can dance in the square to exercise.
Avoid leftovers
High temperature, bad appetite, easy leftovers. The temperature is high, the bacteria propagate rapidly, and the leftovers are easy to be damaged. This summer, if the leftovers are left at room temperature for one night & hellip; & hellip; the next day, the taste of the dishes is only sour!
Xiaobian suggested that we try not to leave vegetables or cold dishes. Vegetables are more likely to produce nitrite than meat and are also susceptible to bacterial contamination.
Cover the leftovers with plastic wrap and put them in the refrigerator as soon as possible. Even if it's in the refrigerator, it's better to eat it in a day. No matter what is left is meat dishes or vegetable dishes, please take them out of the refrigerator and heat them thoroughly before eating. Of course, the best way is to eat as much as you can and cook as much as you like in summer. Don't leave any leftovers.
