Throughout the year, because summer belongs to fire, and because fire is in the heart and fire belongs to yang, the summer heat is the easiest to disturb the mind, make the mood uneasy and cause upset. And upset will make the heart beat faster, increase the burden on the heart and induce diseases. Therefore, keeping in good health in summer focuses on nourishing the heart. First of all, you must be calm, calm and natural. People who are good at nourishing the heart have yin when they are quiet. Only by coordinating Yin and them can they maintain their hearts. How can I be calm? First of all, inner peace must be abstinence. Because the less greed, the less anxiety. You should also be good at adjusting your emotions, especially if you are not happy or sad. Chinese medicine has said that we are either happy or sad. Second, close your eyes more. Close your eyes often when you have time, which can help us get rid of other thoughts. Third, sit still more. Because silence is peaceful, even five minutes will be effective. You can sit quietly in the shade or indoors once 15 ~ 30 minutes. You can also listen to music, read books, fish and play Tai Ji Chuan. There are two kidneys in human internal organs, one is broken and the other is broken. The liver and lungs also have two leaves, but there is only one heart, so the heart is very precious. At the same time, because it works all day, it is regarded as "the most tired organ of the human body". In summer, the weather is hot, the blood circulation is accelerated, and the heart is easily overburdened, so be careful not to be tired in summer. Because only when the heart slows down first and the breathing frequency decreases can the heart rest, and summer is good for health. Low temperature nourishes the heart, and high temperature in summer can easily lead to faster blood flow and faster heartbeat, which will increase the burden on the heart, so high temperature should be avoided in summer. Chinese medicine believes that sweating in summer is the fluid of the heart, and sweating is as easy to be sad as blood and sweat. In addition, high temperature and excessive sweating in summer will not only lead to cardiac and cerebral ischemia, but also increase blood concentration and blood viscosity, which will increase the burden on the heart. Therefore, it is necessary to reduce the intensity of activities in summer and avoid high temperature environment. However, because summer belongs to the sun, the yang is the main drain, so you can't "sweat" when sweating, and you can't turn on the air conditioner for too long. When sweating too much, you can drink a little light salt water to relieve it. Eat nourishing heart. In summer, you should eat more nourishing and calming products. Such as: Poria cocos, lotus seeds, lilies and jujubes. At the same time, we should eat more products that nourish yin and promote fluid production, such as lotus root powder, tremella, watermelon and duck meat. In addition, you might as well eat something "bitter" in summer. Because bitter taste enters the heart, it can nourish yin, clear away heat and relieve annoyance, such as bitter gourd and mung bean. The temperature is rising, and it is another tough summer. For people who love sports, they just like the feeling of being free. As the saying goes: "Practice three or nine in winter and three volts in summer." Summer is hot and sultry, and the human body consumes a lot. The aging of various organs is more obvious than other seasons. If you insist on exercising in summer, its anti-aging and fitness effects will be more significant. However, sports should also adapt to the changes of the four seasons. Why not exercise in another season and see how to exercise in summer? The theory of "nourishing the heart in summer" exists in Chinese medicine. Cardiovascular function is the most sensitive to the change of temperature. Sudden temperature rise will induce angina pectoris and even myocardial infarction. Patients with cardiovascular diseases should pay attention to protect their hearts in hot summer and try to avoid emotional fluctuations such as excessive tension, excitement, anxiety and depression induced by hot summer weather. The purpose of summer exercise is to strengthen the spleen and nourish the heart, benefit qi and promote fluid production, and the way of exercise is to give priority to quietness, supplemented by exercise, and combine static and dynamic, so that the human body can adapt to the summer climate change, strengthen its physique and improve its ability to resist summer heat. Summer heat makes people sweat and make people sad and bloody; Summer heat and summer dampness damage the spleen and stomach, weaken the function of the spleen and stomach, lead to loss of appetite and fatigue. Therefore, summer exercise should be carried out in a way that does not strain the body and mind and does not hurt the body fluid. Exercise in the morning and evening is easy and appropriate. Summer exercise should be scientific, timely, moderate and appropriate. Timely. In order to avoid the harm of strong sunlight to the skin and body, it is best to arrange exercise time in the early morning or in the evening when the weather is cool, and try to avoid outdoor exercise from 10 to 4 pm. Proper amount. In summer, human consumption increases, sleep and appetite decrease, and body reserves are relatively weak. Therefore, we advocate relaxation exercise, the time is controlled at about 20 to 30 minutes, and the intensity is appropriately reduced. We can choose swimming, walking, jogging, boxing and non-confrontational ball games. The right place. Try to exercise outdoors and choose cool and ventilated places such as parks, lakes and courtyards. Even if you exercise indoors, you should open the doors and windows properly to keep the air circulating. Exercise and sweating help to resist heat. The sweat glands on everyone's skin are dense and bear the heavy responsibility of body heat dissipation. When the outside temperature rises to 30℃, sweat glands, a "natural air conditioner", begin to secrete sweat to keep the body temperature constant. Studies have shown that the strength of human heat tolerance is related to the number of heat stress proteins in cells in the body. People who exercise regularly, the synthesis of heat stress protein is obviously increased, their tolerance to heat is enhanced, and they can resist the invasion of high temperature and heat wave. However, people who enjoy air conditioning, far away from the hot environment, reduce the synthesis of heat stress proteins in their bodies and reduce their tolerance to high temperatures. Once they leave the air conditioner and come to the external environment where the heat wave is rolling, it is difficult for them to adapt. The principle of supplementing water and salt balance in time in summer exercise is to keep water and salt balance and a few times. First, it is best not to supplement pure water, but to supplement natural drinking water rich in minerals and trace elements. Drinking pure water will lead to blood dilution and a sharp increase in perspiration, further aggravating dehydration. The second is to replenish water before, during and after exercise. Supplement 200 ~ 400ml； 2 hours before exercise; Add 100 to 150 ml immediately before exercise; Supplement every 10 to 20min during exercise 100 to 200ml according to the weight loss during and after exercise.
