July 6th is the Lesser Heat in the 24 solar terms. Shortly after Xiaoshu, it entered the dog days. Sanfu Tian is the hottest and humid period of the year, known as "heat in Sanfu". There is also a saying in folk culture that "little heat and big heat, steaming on top and boiling on the bottom". How to regulate diet and daily routine, and maintain health scientifically during the dog days? Recently, the National Health Commission invited experts to introduce the relevant situation of "seasonal solar terms and health". Professor Lu Yi from Beijing University of Traditional Chinese Medicine said that summer is prone to symptoms such as mental fatigue, thirst, excessive sweating, chest tightness, and shortness of breath, which are related to the characteristics of heat evil. The first characteristic of summer heat is heat, which can easily consume qi and damage fluids, causing fatigue. The second characteristic is dampness and evil, which can easily trap the spleen and cause problems in spleen and stomach circulation. At the same time, it is easy to get stuck on the watch, causing symptoms such as headaches, heavy head, and body aches. So, in terms of diet, we mainly focus on the two characteristics of heat and dampness to maintain health. For the evil of summer heat, you can add some foods with a cold and refreshing taste, such as mung beans, loofah, cucumber, winter melon, etc., which have a sweet and mild taste and clear heat and dampness. For the characteristics of dampness, you can choose some foods that can invigorate the spleen and dry dampness or invigorate the spleen and dissolve dampness, such as lotus seeds, yam, Job's tears, tangerine peel, etc. For dampness and evil stagnation, you can choose foods such as Su Ye, Huo Xiang, and Sha Ren to dry and relieve dampness, invigorate the spleen and stimulate appetite. In summer, with high temperatures, the body's yang energy tends to float more on the surface, while the internal yang energy tends to be weak. Therefore, special attention should be paid to nourishing yang energy, and one should not overeat cold and cold foods to avoid causing spleen stagnation due to cold and dampness. How to maintain emotional stability in hot weather? Lu Yi said that in summer, special attention should be paid to maintaining a happy and peaceful mood, with a full and upward spirit, in order to make the qi flow more smoothly. Calming the mind, minimizing excessive physical exertion, and avoiding vigorous activities, as sweating can damage yang and easily cause palpitations, palpitations, chest tightness, and other symptoms. In the morning or evening, you can choose some activities that do not require much physical exertion, such as taking a walk, playing eight dan brocade, etc. Taking a short nap at noon in summer can help to calm the mind. If you don't have the conditions to take a nap, you can sit quietly or close your eyes to rest. Massage acupoints, you can massage two acupoints, one is Laogong acupoint and the other is Neiguan acupoint. These two acupoints have the effects of clearing the heart and calming the mind, as well as nourishing the heart and calming the mind. Take care of your diet, drink medicinal tea or take Tonic Diet. You can choose some tea drinks that are both medicinal and edible, and have the effect of soothing the liver and relieving depression, such as brewing tea with jasmine and mint. If the heart fire is intense and accompanied by mouth and tongue sores, dry mouth and tongue, you can make some medicinal teas that clear the heart fire, such as bamboo leaves, lotus seed hearts, etc. If you are tired and have poor sleep, you can use wheat and longan meat to cook Congee, which is beneficial to qi and spleen. How to prevent heatstroke during the Xiaoshu period? Pan Lijun, a researcher at the Chinese Center for Disease Control and Prevention, said that as temperatures rise and humidity increases, it is easy to suffer from heatstroke outdoors and air conditioning sickness indoors. The symptoms of heatstroke mainly include dizziness, blurred vision, headache, nausea, chest tightness, irritability, etc. High risk populations prone to heatstroke include children, pregnant women, the elderly, patients with chronic underlying diseases, outdoor workers, especially those in high-temperature environments. Therefore, try to go out in the early morning or evening when the weather is cooler. When going out in the daytime, take sunscreen and cooling measures, such as wearing sunshades, spray cooling, etc. If the amount of exercise is high, drink a small amount of diluted salt water or sports drinks multiple times to replenish the lost electrolytes in the body. If you experience symptoms of heatstroke such as dizziness, fatigue, and thirst, you should promptly rest in a cool place, replenish water, and cool down. If the symptoms do not improve or worsen, seek medical attention immediately. Air conditioning disease refers to symptoms such as nasal congestion, dizziness, sneezing, fatigue, and memory loss that occur in enclosed air-conditioned environments due to poor air circulation and low temperatures. It is more common in the elderly, children, and women. To prevent such diseases, firstly, clean the air conditioning well; The second is to set the temperature of the air conditioner, which should not be lower than 26 degrees Celsius, and open the window for ventilation for 20 to 30 minutes every 2 to 3 hours; Thirdly, when returning to an air-conditioned room from outdoors, it is important to prevent excessive temperature differences between indoors and outdoors, as sudden temperature changes can easily cause symptoms of air conditioning sickness. Wang Quan, chief physician of Beijing Children's Hospital, said that there is a significant increase in exposure to sunlight in summer, and appropriate sun protection is very important. If there is no ultraviolet light source indoors, there is no need for sun protection. However, if there is a possibility of exposure to ultraviolet rays indoors, such as by windows, with ultraviolet light sources or strong fluorescent lamps, and outdoor activities on cloudy days or under tree shade, sun protection can be chosen. At this point, the sun protection factor of sunscreen products does not need to be too high. Engaging in direct sunlight or being exposed to high-intensity ultraviolet radiation, such as in snow capped mountains, beaches, or plateaus, requires the use of products with a relatively high sun protection factor. Of course, the sun protection factor of sunscreen products should be appropriate, but if it is too high, it will increase the burden on the skin. In addition, even if sunscreen products are applied, it is not advisable to engage in prolonged activity in strong sunlight. Wang Quan introduced that summer is a high-risk season for children's diarrhea. In terms of children's daily care, the following points need to be done: pay attention to food hygiene and safety, keep food fresh, separate raw and cooked food during storage and processing, especially animal food should be steamed thoroughly, vegetables and fruits should be washed and peeled, do not drink raw water, and do not eat spoiled or unclean food. Eat in moderation, avoid overeating, avoid being too cold, eat less raw and spicy food. Pay attention to personal hygiene and environmental hygiene. Wash hands before and after meals, disinfect utensils, and thoroughly heat leftovers and overnight food before consumption. Try to implement the serving of individual dishes to reduce the risk of infectious diseases in the digestive tract. Pay attention to indoor ventilation, do not let the air conditioning temperature be too low, and do not let the fan blow directly to avoid getting cold. During the summer vacation, maintain a good daily routine, have a reasonable diet, exercise regularly, engage in moderate outdoor activities, and enhance resistance to diseases. (New Society)
