We live in the northern hemisphere, and there are four seasons in a year: spring, summer, autumn and winter. After winter, with the temperature rising, the heat absorbed by the ground is also increasing, and the ground absorbs more heat and dissipates less heat. In July and August, the subtropical high in the northern hemisphere caused the internal airflow to sink. At this time, the external environment is sunny and partly cloudy. It is precisely because there is no cloud that the time and intensity of direct sunlight on the ground increase, resulting in higher temperature and hotter weather. In addition, the heat absorbed by the surface continues to accumulate, leading to hotter and hotter temperatures! Entering the dog days, the heat absorbed and accumulated on the ground also reaches the highest, so the temperature is the hottest.
In addition, with the increase of rainfall in summer, the air and surface humidity become larger, the temperature becomes hotter and hotter, and the heat capacity ratio of water is much higher than that of air, which leads to sultry weather, so the dog days are also the peak of summer evil. As the saying goes, the summer heat is boiling, and in summer and autumn, the heat wave attacks people, the heat is unbearable, and sauna days with high temperature and humidity frequently appear, causing various health problems one after another, such as heatstroke, cardiovascular disease and heart failure.
It's very hot in dog days. If you sweat a lot and consume a lot, it will easily lead to fatigue and decreased digestive function. If you don't pay attention to diet and don't adjust it through diet, it will easily lead to the decline of body immunity, which will lead to diseases. How to live in dog days? Most people think that heatstroke prevention is the most important thing in dog days, but in fact this concept is one-sided. Should we prevent heatstroke in dog days? Of course. However, while preventing heatstroke, we should pay more attention to cold protection.
Because, after entering the dog days, correspondingly, the yang of our human body is also the most prosperous in a year. At this time, the pores are opened, the sputum is opened, and the blood vessels are also in a state of expansion, and the defense against foreign evils is the weakest. At this time, once the temperature drops, cold evil will take the opportunity to enter. In addition, with the arrival of summer, people like to stay in air-conditioned rooms for a long time, blow on electric fans and eat cold food. These behaviors virtually contribute to cold evil and endanger our health. However, many diseases of human body are caused by insufficient or damaged yang, which can not resist the invasion of external evils.
Therefore, we should be vigilant and never take it lightly and ignore the cold evil in summer. You know, in the hottest summer, the importance of cold protection is even higher than heatstroke prevention. The so-called winter disease is probably the accumulation of exogenous pathogens in the body and the outbreak in winter.
If you don't pay attention to your health in the dog days, you will get cold, such as taking a cold bath, turning on cold water, blowing air conditioning, and eating iced food and preserved fruit often, the consequences will be very serious. So how to deal with the invasion of cold evil into the body in dog days? Lao Yu summed up these three tricks!
First, avoid cold directly entering the body. No matter what cooling methods are adopted, such as turning on the air conditioner, blowing the electric fan, enjoying the cool outdoors, swimming and taking a cold bath, it is necessary to avoid Chen Qin for a long time. Don't open the doors and windows to ventilate when you sleep at night, in case of evil spirits and thieves.
Second, protect your throat, back of your head and knees. The throat, the back of the head and the knees are the most vulnerable parts of people. If you are not careful, you will be easily attacked by the cold. Protecting the delay and the back center helps the body to buffer the erosion of low temperature and cold.
Third, eat less cold food, especially children. Because the child is in a state of growth and development, Yang is also growing and needs protection. Excessive drinking of cold drinks is bound to hurt the yang in the body, causing greater harm than adults. It is prone to gastrointestinal and respiratory diseases such as spleen and stomach deficiency and cold, nasopharyngitis. Symptoms are poor resistance, repeated inflammation and fever of tonsils, disharmony between spleen and stomach, and easy to get sick.
Therefore, in order to protect the yang in the body, the correct way in dog days is to drink warm water. How about drinking hot water? In China, we often say that drinking hot water often can cure all diseases, such as colds, fever, physiological period and stomachache.
So what is the purpose of drinking hot water in dog days? Mainly for sweating, that is, the function of sweating and relieving exterior syndrome in traditional Chinese medicine, which plays the role of dredging the interior and clearing heat. But this is just a way of keeping in good health, not a panacea. It takes a long time to persist, and it is impossible to discharge all the cold in the body only by drinking hot water for a short time.
In fact, to drive away the cold, proper exercise, sweating, soaking feet and other ways can drive away the cold as long as you sweat slightly. Of course, this requires long-term persistence. At the same time, it is worth noting that the purpose of sweating is to drive away the cold, so don't sweat at that time. In order to be greedy, I didn't change my wet clothes in time, but it aggravated my cold.
In dog days, to prevent colds and ensure good health, we should also pay attention to eating less cold foods such as watermelon, persimmon, crab, mussel, bamboo shoots, amaranth, cucumber, lotus root, turtle and mung bean, and eat more warm foods. Lao Yu suggested drinking warm ginger and jujube tea in dog days. Please pay attention to health care, heatstroke prevention and cold prevention in dog days.
