The summer solstice is the arrival of the hot summer. At the summer solstice, the Big Dipper points to B. The sun’s ecliptic longitude is 90°. When the sun is at the “summer solstice” point at 90°Ecliptic, the sun is almost directly over the Tropic of Cancer, and the noon sun is the highest in the northern hemisphere. This day is the longest day and the shortest night in the northern hemisphere, from this day onwards, into the hot season, everything in heaven and earth at this time the most vigorous growth. So the heart to the ancient times and this day is called the day north to, meaning that the sun transported to the most northern day. After the summer solstice, the sun gradually moved south, the northern hemisphere day shorter than a day, the night longer than a day. In Chinese medicine health theory, the summer solstice is the most vigorous Yang season, this time of health care, on the one hand, we should comply with the summer Yang Sheng outside the characteristics, pay attention to the protection of Yang; on the other hand, the summer solstice is also the so-called “Yin and Yang fight for death and life” of the time, as the saying goes, “summer solstice On the other hand, the summer solstice is also the time of the so-called “yin and yang struggle for death and life”, as the saying goes, “the summer solstice is the birth of yin”, which means that despite the hot weather, yin has already started to grow. After the summer solstice, there are the first, middle and last volt, and the three volt days are the hottest period of the year, making it easy to get heatstroke and sick. Therefore, in the old days at this time more exorcise ghosts for peace, but also pay attention to noon break zhu, pay attention to eat tonic food. In addition, special attention should be paid to prevent heatstroke. Nonetheless, summer is also a big drain on the human body, because it is not good to eat and sleep, and is tormented by the heat, so it is called dry summer. It is a custom in the north to weigh a child regularly to see if his weight has increased or decreased in order to observe the growth of the child. 1, living and health living Jikang “health theory” said: “more appropriate to regulate the rest and quiet mind, often as ice and snow in the heart, the heat is also in or heart less reduction, can not be hot for hot, reborn hot carry on.” If you think of snow and ice in your mind, you will not feel the heat. In order to comply with the natural yin and Yang changes, it is generally advisable to go to bed late and get up early in summer, try to keep about 7 hours of sleep every day. The summer solstice should sleep late and get up early, not to sleep at night. To adapt to the changes in the natural world, it is advisable to sleep late and get up early. The summer heat, “summer heat is easy to hurt the gas” if the sweat is too much, people dizzy chest tightness, palpitations and thirst, nausea and even coma. When arranging outdoor work and physical exercise, you should avoid the scorching heat of the sun to strengthen protection. Reasonable arrangements for lunch break, one to avoid the heat of the momentum, the second can restore the sense of fatigue. Daily warm water bath is also worth advocating fitness measures, not only can wash off sweat, dirt, so that the skin is clean and cool to prevent summer heat, and can play the purpose of physical exercise. Because, warm water shower water pressure and mechanical massage effect, can make the nervous system excitability is reduced, the body surface vascular expansion, accelerate blood circulation, improve skin and tissue nutrition, reduce muscle tension, eliminate fatigue, improve sleep, enhance resistance. In addition, the summer heat, the coup open, vulnerable to wind, cold and moisture, sleep should not fan class wind, air-conditioned rooms, indoor and outdoor temperature difference should not be too large, and should not sleep at night. 2, sports health summer solstice sports should be in the early morning or evening summer sports are best selected in the early morning or evening when the weather is cooler, the site should be selected in the river and lake water, the park courtyard and other places of fresh air, people with conditions can go to the forest, seaside areas to convalescence, vacation. Exercise projects to walk, jogging, taijiquan, radio exercise is good, should not do excessively strenuous activities, if the exercise is too aggressive, can lead to sweating, sweat drain too much, not only hurt Yin, but also appropriate to lose Yang. In the process of exercise, sweating too much, can be appropriate to drink light salt water or mung bean salt water soup, do not drink a lot of cold water, not immediately with cold water shower, shower, otherwise it will cause cold damp paralysis, yellow sweat and many other diseases. 3, diet health summer solstice diet should eat bitter, sour and salty diet regimen, there are summer when the heart fire when the order, the heart fire is too strong to grasp the lung gold (the five elements of the view), so the “Golden Horoscope” has “summer does not eat the heart” of the statement. According to the interrelationship of the five elements (summer is fire), the five elements (summer is long), the five organs (heart) and the five tastes (bitter is appropriate), bitter tasting things can also help the heart qi and control the lung qi. Summer is also the season of sweating, sweating, the loss of salt is also more, if the heart muscle salt deficiency, the heartbeat will appear abnormal. Chinese medicine believes that at this time it is advisable to eat more sour to strengthen the surface, and more salty to nourish the heart. The Suwen – Zang Qi Fa Shi Lun said: the heart is the main summer, “the heart is bitter and slow, eats acid to collect it”, “the heart wants to be very good, eats salty to be very good, with salty tonic, sweet diarrhea”. That is to say, the Tibetan Qi is good soft, so the salty soft also. From the point of view of yin and yang, the summer month of volatile yin within, diet should not be too cold, such as “Yi body set” said: “summer heart and kidney failure, although the heat should not eat cold amoy ice and snow, honey water, cold powder, cold porridge. Full stomach by cold, will start cholera.” The heart wants kidney failure, that is, the external heat within the cold meaning, because of its external heat within the cold, so cold food should not eat more, less is still possible, greedy more will certainly be cold injury to the spleen and stomach, people vomit and diarrhea. Watermelon, mung bean soup, plum bean soup, although for quenching thirst and summer heat of the good, but should not be chilled food. According to the relationship between the organs and organs of Chinese medicine, “the kidney without the fire of the heart is cold, the heart without the water of the kidney is hot. The heart must get kidney water to moisten, the kidney must get heart fire to warm” from which it is easy to see the important relationship between the heart and kidney. Diet in the hot summer climate, people’s digestive function is relatively weak, therefore, the diet should be light and should not be fat, sweet and thick, to eat more food to cold their bodies, not over-eating hot food, so as not to help heat; cold food melons and fruits when moderate, not over-eating, so as not to damage the spleen and stomach; thick fatty products should be less than more, so as not to heat the wind, stimulating the disease of boils. Here, I would also like to recommend an ingredient – ginger. There is a saying: “rice does not smell good, eat ginger”, “eat radish in winter, eat ginger in summer”, “three slices of ginger in the morning, than drinking ginseng soup”, are the nutritional value and medical role of ginger The nutritional value and medical effects of ginger are well summarized. Summer heat, most people’s appetite, and ginger is good for food digestion and absorption, for summer heat has certain benefits. Another “men can not be a hundred days without ginger” said. In the summer, everything grows, yang and yin, heart and kidney failure, so the right amount of tonic for men’s sexual function to protect and enhance or very good. 4, the spirit of health “Su Wen – four gas tuning Shen Da Lun” said: “so that Zhi no anger, so that Huaying into the show, so that the gas to drain, if the love outside, this summer gas should be, the way to raise long”. That is, the summer should be clear, happy and cheerful, broad-minded, full of spirit, such as everything needs sunlight to grow, to have a strong interest in the outside world, to develop an optimistic and extroverted character, in order to facilitate the flow of qi. Contrary to this, all slack and boredom, anger and depression, it is not appropriate to hinder the flow of qi jump. Jikang “health theory” on the hot summer has its unique views, that the summer heat, “more appropriate to regulate the quiet mind, often as ice and snow in the heart, the heat is also in my heart less reduction, can not be hot for hot, rejuvenated hot carry on.” That is, “the heart is quiet and naturally cool”, here is the summer health method of spiritual conditioning.
