This year's July 15 ambush, unlike previous years, the dog days in 2024 will last for a full 40 days, and the dog days that last for more than a month can be described as the longest summer hot weather in history, so what impact will such a long period of hot weather bring us?
The high temperature weather will have a certain impact on the construction of cities and the cultivation of agriculture, and will also bring inconvenience to people's travel, such dog days are also full of challenges and opportunities.
Hot weather can undoubtedly take this opportunity to test our willpower and perseverance, and test people's resilience in the face of various difficulties, so we should also protect ourselves and make certain adjustments to our lives and work.
So what should we do in hot weather?
Dog days are not ordinary.
Dog days are the ancient solar terms in the past on the mainland, and it is also the hottest period of summer in the mainland, so there is a saying of "dog days" in ancient times, which is enough to see the heat of dog days.
So how are dog days divided?
Among the 24 solar terms, the beginning of autumn is the first solar term, which is when the summer days are gradually coming to an end.
Therefore, the days between the beginning of autumn and the dog days are the dog days, and the dog days have no specific date, but are a period of time, and few people know the existence of dog days before the seventies of the last century.
And what about the dog days now?
In the book "Chinese Meteorology", there is a detailed introduction to the 24 solar terms, which has a sentence "according to the difference between the time of the beginning of autumn and the time of Qingming in the year", the popular point is that the time span from Qingming to the beginning of autumn is different, and the time period of dog days will be different.
In 2024, the beginning of the dog days will end 40 days later, starting from the beginning of the ambush on July 15, and thus the longest dog day division in 25 years has come to an end.
It can be seen that the dog days in ancient times were basically the time from Qingming to the beginning of autumn, and today it is already after the beginning of autumn, and this time will also change with the change of temperature and season.
The ancients' division of weather and seasons was also summarized according to their living habits and experience, which may seem a little unreasonable today, but the ancients' sensitivity to climate and seasonal changes and their ability to summarize cannot be measured by IQ.
During the dog days, people should also make corresponding preparations in life and work, especially should pay attention to shading, sun protection, and heat protection.
In the fields in the countryside, you can even see the figure of farmers ploughing, it is a busy time for farming, they rush to start the work of farming before the arrival of dog days, which contains a wealth of agricultural knowledge, farmers also have to plant crops according to the changes of seasonal climate when farming, it is because of the farmers' diligence to create a wealth of agricultural products.
These agricultural products can not only meet people's daily food, but also have rich nutrition, and play a good role in people's health.
Dog days are also the hottest time of the year, when people can regulate their bodies and nourish their bodies through dietary therapy, which is also the time when the ancients formed dietary therapy knowledge.
In addition to the heat, there is also humid weather during dog days, so people are still prone to be a little lazy during this time, and if they are in a bad mood, they are also prone to some depression, so the ancients will also carry out some medicinal baths to invigorate blood circulation at this time, so that they can get rid of diseases, and they can also make their mood happy.
The impact of hot weather on life.
Up to 40 days of high temperature weather to our life and work has a greater impact, especially in the city, due to high-rise buildings and excessive flow of people in the city to form the city's thermal effect, this thermal effect will also cause the urban heat island effect, is the city's high temperature phenomenon is more serious.
In recent years, the rapid urbanization of the mainland has become more and more rapid, so the urban heat island effect is more serious, and the high temperature in the city will be much higher than that in the countryside, and when we are in such an environment for a long time in the high temperature environment, the body will rise because of sweating and heat dissipation, and heat stroke will occur.
Therefore, at this time, we need to take measures to prevent heatstroke and cool down, and try to minimize the time spent outdoors, from 6 am to 4 pm is the golden time for us to cool down against heatstroke.
At this time, whether it is the elderly, children or office workers, they should reduce the time for wandering outside or doing more strenuous exercises, give their bodies a time to rest, and take a lunch break at noon, do not be exposed to the sun outside, minimize direct sunlight, you can choose to read books indoors, and carry out some indoor recreational activities.
In addition to reducing outdoor time, we can also use some small props to prevent heat stroke and cool down, such as umbrellas, sun hats and other sunshade equipment, which can effectively avoid direct sunlight, and we should also bring some sunscreen products for outdoor activities.
Drinking water is also a tip for us to prevent heatstroke and cool down, because when our human body sweats, it will take away the water in the body, so we need to replenish water when we sweat, so that the body can not only prevent dehydration, but also control the body temperature in a lower state.
Because in hot weather, our appetite will also become very poor, but we can't skip meals because of bad appetite, which is not good for the body, drinking porridge is a good choice, which can not only replenish water but also maintain the body's nutritional balance.
How to prevent heatstroke and cool down.
In such a high temperature weather, crops will also be affected to a certain extent, under normal circumstances, the temperature in summer will be around 30 °C-35 °C, the temperature at this time is more suitable for most crops, and the growth rate is relatively fast, but when the temperature rises all the way, as high as 40 °C-45 °C, the impact on crops is gradually increasing.
The high temperature not only causes the water in the soil to evaporate quickly, but also increases the rate of photosynthesis of crops, which greatly reduces the nutrient content of crops.
In such a high temperature weather, the growth rate and growth rate of crops will also be greatly reduced, and some crops will even grow some diseases, which will be seriously affected, and will also have a certain impact on agricultural output.
In order to cope with such temperatures, people don't know how many ways to prevent heatstroke and cool down, in addition to reducing the time spent outdoors, we can also take in more water, and we can prepare some small items to prevent heatstroke and cool down, such as ice cubes, fans, parasols, etc., to keep the head and neck cool down at all times, after all, this is the human respiratory tract, which is the place where our body discharges heat.
In hot weather, our blood is also in a dilute state, if the air conditioner is blown at this time, then the dilution of blood will make our body's judgment of temperature will also be out of balance, and the temperature outside the air-conditioned room will feel hotter.
So in such a hot weather, we might as well try to close the window and rely on the fan to cool down, but also to keep the bedroom ventilated, in addition to changing clothes frequently, thin clothes are the best choice.
In addition, be sure to protect your skin in hot weather, wear sunscreen when you go out, and pay attention to shade even indoors, sunscreen can not only protect from the sun, but also moisturize, so you might as well give it a try.
epilogue
The existence of dog days allows us to travel in the sky in the hot weather, and at the same time brings abundant agricultural products to our lives, agricultural production is cultivated in such a climatic environment, and people will also have a sense of awe for nature in this kind of work, and the perception of nature is also experienced in this kind of work.
We have very little grasp of this temperature, but today, when the global temperature is rising year by year, we can also think about the reason behind it, whether it is climate change caused by human factors, or caused by natural factors, no matter which one it is, we should find ways to reduce this impact and protect the environment.
In such weather, we must take some measures to prevent heatstroke and protect our body, on the other hand, the high temperature phenomenon at this time can also make us pay more attention to our body, cultivate good living habits, and make our body healthier.
