When there is a haze, it is best not to exercise outdoors. You can perform tai chi, yoga, and other soft exercises at home. If you want to go outdoors, first, the amount of exercise should not be too large, too much exercise is easy to sweat, body fluids, blood discharge with the sweat will cause some damage to the body. The second is to properly reduce the exercise time, usually two hours of exercise can be properly reduced to one hour or half an hour, so that not only achieve the effect of exercise will not cause harm to the body. In addition, wear a mask before you go out.
The winter solstice will come on the 22nd of this month. The winter solstice is the shortest day and the longest night in the northern hemisphere throughout the year. Originally only discussed the topic of protecting the cold, but let the haze that frequently visit gives the new content of the winter solstice health. Recently, Dong Sheng, Associate Professor and Deputy Chief Physician of the Affiliated Hospital of Shaanxi University of Traditional Chinese Medicine, talked about his views on the topic of Winter Solstice.
The most important of the winter solstice “protecting the Yang†hands and feet
After the winter solstice, it began to count "nine" and every nine days was a "nine." Before and after the March 19th, the area had the least amount of heat and the weather was coldest. It is especially important to protect your own yang at this time. Dong Sheng said that the best way to maintain his own yang in the winter is to enjoy the sun. The winter sun is called "warm sun" because it doesn't feel like it's hot in summer. In the winter, the ultraviolet rays in the sunlight are not as strong as in the summer and will not cause harm to the skin. In addition, frequent sun exposure in the winter is beneficial to the absorption of calcium, which not only can prevent osteoporosis, but also can assemble and protect the yang itself. Older people can gently hit their backs in the sun to achieve better results.
In addition to the sun, the protection of hands and feet is also very important. Chinese medicine believes that hands and feet are the transfer part of the body's meridian circulation, that is, the place where the yin and yang are transferred. Therefore, the protection of hand and foot in winter can not be ignored. "A long period of cold in the feet and lower extremities can easily lead to many diseases such as leg pain, back pain, and dysmenorrhea in women," Dong Shengru said. In his opinion, some young women wear thin clothes in pursuit of beauty. If they continue to grow down, they will lay hidden dangers for the old cold legs and other diseases. Therefore, Dong Sheng suggests that the most important thing in the cold winter is keeping feet and lower limbs warm. In particular, women should wear warmer footwear after the winter solstice. At the same time, it is necessary to develop the habit of bathing at night. The feet can not only protect the cold but also promote the blood circulation of the feet, and have a good effect on the body, especially the lower limbs.
Light diet slow exercise
The red warning of heavy pollution caused by air from the 8th to the 10th of this month has caused Beijing residents to experience another fight against the enemy. Since the arrival of winter, the haze has been visited again and again, making it easier to enjoy the sunshine in the winter. In this regard, Dong Sheng said that selectively increasing the anti-smog diet, combined with good living habits is an important measure to deal with hazy weather.
Dong Sheng said that the winter solstice is a good time for health, mainly because "qi began in the winter solstice." White radish and jujube are good ingredients for the winter solstice. From the perspective of Chinese medicine, the white radish is sweet and sweet, and is suitable for people who have a lot of indigestion, dyspepsia, and poor urine. Jujube is not only qi and nourishing, it is suitable for anemic or cold female hands. In haze weather conditions, the diet should be light, eat more vegetables and fruits to supplement vitamin C, you can also eat some lily, Sydney, lotus root, honey, etc., to improve their immunity, avoid hazy days induced some diseases.
The increase of various pollutants in smog days not only affects the system of respiration and circulation, but also causes smog particles to accumulate on human skin. Therefore, Dong Sheng suggested that after returning from a hazy day, be sure to wash your hands, wash your face, and wash away the stickies on the skin. In addition, it is also necessary to clean the furniture on time to prevent dust from staying in the home for a long time to affect the circulation of air and cause illness.
"Because the smog-laden air contains more tiny particulate contaminants and pathogens, it can directly affect the respiratory tract, causing or aggravating various respiratory diseases such as upper respiratory tract infections, bronchitis, and asthma attacks; it will also increase the blood circulation system. The burden, coupled with more and more cold weather, will increase the incidence of cardiovascular and cerebrovascular diseases. Therefore, when there is haze, it is best not to exercise outdoors. You can perform Tai Chi, yoga and other soft exercises at home. If you want to go outdoors, first, the amount of exercise should not be too large.Excessive exercise can lead to sweating, body fluids, and qi and blood can cause certain damage to the body with the discharge of sweat.Second, it is appropriate to reduce the exercise time, and usually exercise for two hours. Can be reduced to an hour or half an hour properly, so that both the effect of exercise and physical harm will not be achieved. In addition, wear masks before going out to prevent smog pollution." Dong Sheng said.
Choose the correct face mask
The first step: Check the implementation standards on the mask package.
See if there is a clear and accepted mask implementation standard. Generally speaking, N95, N90, etc. begin with the American standard, the first with the FFP is the European standard, and the first with the KN90, KN95, KP100 is the Chinese standard.
Step 2: Try on it to see if it fits your face.
The masks that can prevent particles use special filter materials, and rely on the three-dimensional structure design to form a space that is sealed on the face and rely on human inspiration to force the contaminated air to filter and breathe.
The relevant experimental data show that the 3M mask with no breathing valve has the best filtering effect, and the PM2.5 filtration rate can reach 95.5%. The most obvious filtering effect in ordinary masks is a one-time medical nursing mask, with a filtration effect of 47.1%. However, the common people The most familiar and commonly used cotton mask, the filtering effect is only 17.3%. (Wu Ying)
