”Glamorous bar, a scantily clad fashion girl, stretched legs, holding a tall cocktail glass, elegantly smoking a cigarette, between the lips pouring out the smoke ring ……” This is the usual shot used in many film and television works to show the female characters The fashionable and elegant. In life, the second leg has also become the most common leg posture of modern women at work and leisure. However, stilted legs are not as comfortable and noble as we know, behind such a popular posture, who would know that stilted legs are actually slowly harming our health? Not only women, many people around us sitting in chairs, are habitually crossed legs, and even after sitting down immediately stilted legs become subconscious habitual action, some people may feel more comfortable, especially women think that stilted legs are very elegant. But in fact, behind the surface of the elegant legs, is the potential cause of disease. Today we’ll talk about the relationship between the “second leg” and health, especially with cardiovascular disease. So how did the word “erlang-legged” come about? Our poet Liu Shahe has written an article “The Explanation of Erlang-leg”, which explains the origin of Erlang-leg in a funny way. He pointed out: “Erlang-leg” is not only in Sichuan Province, but also in other provinces. This is the sitting posture of Erlang Shen. The statue of Erlang on the main hall of my hometown Chuan Wang Temple and the old statue of Erlang in Dujiangyan Temple in my Shu are in this shape. The legend says that Erlang was the second son of Li Bing, the county sheriff in Qin Dynasty, who helped his father to cut the pile and eliminate the scorpion, and after his death, he was named Erlang God. In technical terms, the “Erlang leg” should be the Yu step. According to legend, the Great Yu made every effort to heal the water, but after ten years of not entering the house, he became paraplegic, one leg stiffened and became a cripple. Later, a sorcerer performed a spell, hopping on one foot and stilting on the other, claiming to be the “Yu step”, which is actually an imitation of Dayu. After the evolution to this day, is called “Erlang legs”. Crossed legs due to sitting deformation, although temporarily feel comfortable, but after a long time will cause a variety of physical discomfort and disease, seriously affecting health. If the normal human spine should be “S” shaped from the side, and when the legs are hunched over, over time, the spine will form a “C” shape, resulting in uneven pressure distribution between the lumbar and thoracic spine. The pelvis and hip joints are prone to soreness and pain due to long-term pressure, which can lead to bone lesions or muscle strain and compression of the spinal nerve, causing back pain. Especially when riding the bus, if you encounter emergency brakes, the crossed legs can not be flattened in time, easily lead to dislocation of bone and joint muscle damage. When stretched legs, the legs are usually clamped too tightly, raising the temperature around the inner thighs and genitals. For men, this high temperature can damage sperm, long-term, may affect fertility. The elderly people have an enlarged prostate gland, and prolonged stretches of legs will compress the pelvic floor muscles to contract and expand the enlarged prostate gland to the urethral tube, thus compressing the urethra and thus causing difficulty in urination. The actual fact is that you can find a lot of people who are not able to get a good deal on a lot of things. The fact that women stretched their legs will also lead to an increase in local temperature, which creates a warm and humid environment in the perineum, can cause pathogenic bacteria to multiply, thus causing vulvodynia or vaginitis. If the pathogens infect the genital tract and spread, it may affect the entire pelvis. In addition, people with a history of dysmenorrhea, often stretched legs may also aggravate dysmenorrhea. The hot sun, the elderly outdoor activities reduced a lot, the home of the card table has become the old sisters to exercise the mind of the battlefield. Once the weekend was over, the children went to work and school, and the four old sisters could have a good time playing, and before they knew it, it was dawn. The company’s main goal is to provide the best possible service to its customers. Hurry to the hospital, after examination and diagnosis: coronary heart disease, hypertension, diabetic foot. The company’s main goal is to provide a good solution to the problem. It is well known that the elderly are often hypertension, diabetes, coronary heart disease, cerebrovascular disease, atherosclerosis is the basic pathological basis of these diseases, especially diabetes, hypertension is accompanied by lower limb vascular plaque to narrow or even occlusion. When stretched legs, the N artery and N vein in the bend of the calf on one side are compressed by the knee, which very easily affects the blood circulation of the lower limbs. Both legs remain in one position for a long time, easy to numb, if the blood circulation is then blocked, poor venous return, is likely to cause varicose veins or thromboembolism in the legs. Poor upward blood flow will also reduce or slow down the amount of blood returning to the heart and brain, affecting the brain and heart function, also easy to induce hypertension, coronary heart disease, etc., especially the elderly with cardiovascular disease, should be more alert. Diabetic patients vascular lesions are usually multiple and diffuse lesions, the lower limbs are more prominent, prolonged cross-legged arterial outflow is blocked to affect the end of the lower limbs blood supply, can lead to limb ischemia or even necrosis, and become diabetic foot disability. From this point of view, not to feel comfortable sitting is a good sitting posture. The correct sitting posture should be straight upper body, tuck in the abdomen, jaw slightly closed, and both lower limbs together. If possible, the knee joint should be slightly higher than the hip. If you sit on a chair with a backrest, you should try to put your back as close as possible to the back of the chair on the basis of the above posture, so that the muscles of the lumbosacral region will not be fatigued. After sitting for a long time, you should move around and relax the muscles of the lower limbs. Long-term sedentary people, or people with the above-mentioned chronic diseases, it is best to less stretched legs. If you can’t change it for a while, you should also consciously control the time of stretched legs, legs should not cross too tightly, a few minutes should change a sitting posture, or after a period of time, stand up and walk around more. This can avoid the damage caused by “two legs” to us.
