The hot climate in summer makes it easy to get heatstroke, and the high humidity of the air makes food and drink easy to spoil, which is accompanied by a high incidence of heatstroke and intestinal infectious diseases. At the same time, according to the principle of “spring and summer nourish the yang” in Chinese medicine, it is also a good time to carry out “winter diseases and summer treatment”. In high temperature and high humidity or strong radiation weather conditions, because the temperature is higher than the skin temperature, radiation, conduction and convection heat dissipation mechanisms can not be maintained, making the body sweat secretion, evaporation becomes the main way of heat dissipation, if people spend a long time in the hot outdoor activities will lead to thermoregulation dysfunction, and eventually heat stroke. Prevention of heat stroke first of all, we should eat a reasonable diet, food should be light, especially the elderly should eat less and more meals. To supplement sufficient food nutrition to meet the physiological needs; to drink more water (cool white water with a small amount of salt is better), even if you are not thirsty to drink water, not less than 1,000 ml per day is appropriate, sweat more when you have to increase the amount to replenish the loss of water and salt and maintain the amount of circulating blood. Secondly, we should learn to combine work and rest to avoid excessive fatigue, especially when working in the heat, we should pay attention to the heat and do not work for too long or too tired. Also adhere to the appropriate physical exercise, but the exercise time should not be too long, the amount of exercise should not be too large, a slight sweat can be, after the exercise to pay attention to the water supplement. Finally, the summer can be commonly used honeysuckle tea, or take patchouli water, ten drops of water and other drugs, can effectively prevent heatstroke. Summer is the season of infectious diarrhea, which is mainly caused by bacterial infections, such as typhoid, paratyphoid, bacterial dysentery, cholera and bacterial food poisoning. The pathogens of patients with intestinal infectious diseases are discharged from the feces and vomit of patients and pathogen carriers, contaminate the surrounding environment, and then enter the gastrointestinal tract through water, food, hands, flies, cockroaches and other media through the mouth, reproduce and produce toxins in the human body to cause morbidity, and continue to discharge pathogens to infect other healthy people again. Therefore, it is important to pay attention to dietary hygiene in summer and do preventive work. Do not eat rotten food, raw vegetables, fruits and vegetables must be washed and scalded, leftovers, leftovers should be cooked before eating; tableware should be frequently disinfected; do not drink raw water, drink boiled water; pay attention to personal hygiene, the habit of washing hands before meals, after the stool; usually more physical activities to enhance physical resistance; in addition, you can choose the appropriate Chinese herbal tea drinks and other targeted prevention. The period from summer heat to the beginning of autumn is divided into three volts, also known as the “summer of volcanoes”, during which the year’s highest temperature and Yang energy is at its peak. For some chronic diseases that often occur in winter and diseases with Yang deficiency and Yin cold, such as bronchitis, chronic bronchitis, emphysema, pulmonary heart disease, bronchial asthma, chronic diarrhea, deficiency cold stomach pain, abdominal pain, back pain, limb pain, etc., at this time, you can take advantage of the high heat of nature and use hot drugs or warm therapy to help Yang dispel cold and regulate immunity, which can help to improve the condition and effectively prevent recurrence in winter, and even cure it completely. It can even be completely cured, which is called “winter disease summer treatment”. The specific methods can be selected according to the different diseases, such as compressing acupuncture points, burying needles, moxibustion treatment, internal consumption of traditional Chinese medicine and fumigation and other methods. In recent years, “winter disease summer treatment” has been widely carried out in the acupuncture department of many hospitals in China, and has achieved very good clinical and social benefits.
