There have been many studies abroad on the effects of prolonged sitting and standing on physical health. Generally sitting for more than 2-4 hours is called sedentary. Research shows that most Chinese people sit and stand for 6-9 hours a day or more. If the daily sitting and standing time in 9.6 hours, the incidence of neck sprain (oblique muscle tension for a long time), upper back pain, heart disease, colon cancer (every 2 hours more sitting, colon cancer risk increased by 8%), low back pain, joint pain, varicose veins, osteoporosis, obesity, lumbar disc herniation, etc. will increase very much. Sedentary damage heart: sedentary less mobile, blood circulation slowed down, blood viscosity increased, myocardial contraction weakness, over time, atherosclerosis, coronary heart disease, stroke, etc. will come along. In recent years, we have heard of many cases of sudden myocardial infarction in office white-collar workers, how can this disease happen at a young age? Sedentary less mobile, blood circulation slowed down, blood viscosity increased, myocardial contraction weakness, over time, atherosclerosis, coronary heart disease, strokes, etc. will come along. Some information shows that the risk of coronary heart disease is four times higher in sedentary people with little movement than in people who exercise regularly or manual workers. There is also information showing that the incidence of cerebral infarction increased by 13.6% in sedentary people over 35 years of age who move less than those who exercise regularly, and the incidence of cerebral hemorrhage increased by 22%. Sedentary brain injury: sedentary, blood circulation slowed down, will lead to insufficient blood supply to the brain, injury to the brain, mental depression, manifested as body fatigue, neurological depression, aspirated. This is also the most common symptom of our current office workers, if suddenly stand up, there will be dizziness and dizziness. Sitting and thinking about blood and yin, the elderly will lead to memory loss, inattention. Sedentary prone to cervical spondylosis: one of the main reasons for cervical spondylosis is sedentary. Sitting down to study and work, the balance between the cervical vertebrae is out of balance, the ligaments, tendons and tendon sheaths in the neck do not get the relaxation they deserve, resulting in the formation of cervical spur hyperplasia, cervical ligament calcification, ossification, cervical vertebrae then stiffen and straighten, resulting in different types of cervical spondylosis. Sedentary neck, shoulder and back continue to maintain a fixed posture, the intervertebral disc and interspinous ligament in a state of tension and rigidity for a long time, will lead to stiffness and pain in the neck, shoulder and back, or pitching and turning difficulties. In particular, improper sitting posture (such as the crest continues to bend forward), but also prone to hunchback and osteophytes. Chinese medicine has long recognized that “sitting hurts meat”. Sitting, blood is not smooth, the lack of movement will make muscle relaxation, elasticity, lower limb swelling, tiredness, heavy will make muscle stiffness, pain and numbness, triggering muscle atrophy. Think back, you went to work all day, is not always feeling back pain leg cramps ah! The woman who often works in the office is sedentary will lead to “poor pelvic blood circulation, so that the ovaries do not have enough blood supply and lack of oxygen”, which is a major reason for the increase in infertility in modern women. Many women in their 30s who sit in offices often have severe pain before and during menstruation due to prolonged sedentary lifestyle. This is due to sedentary lifestyle and lack of normal exercise, resulting in impaired circulation of Qi and blood and poor blood circulation in the lower abdominal cavity, including the pelvic cavity, resulting in insufficient blood supply to the ovaries and lack of oxygen. 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 actual fact is that you will find a lot of people who are not able to get a good deal of money from the internet. This is because office workers sit on soft seats for a long time and keep the same sitting posture for a long time, so that the blood flow below the abdomen slows down and affects the normal operation of blood circulation. At this point, the rectal veins are prone to varicose, leading to blood pooling and eventually forming a venous mass, which is where hemorrhoids form. Several studies at home and abroad have found a phenomenon that the risk of colon cancer is significantly higher among sedentary office workers than among people who exercise regularly and manual workers. This is because long-term sedentary people at the desk have weakened and slowed down intestinal peristalsis, and harmful components in feces, including carcinogens, remain in the colon and stimulate intestinal mucosa, plus poor blood circulation in the abdominal cavity, pelvis and lumbosacral area of sedentary people, which can lead to a decrease in intestinal immune barrier function, all of which increase the risk of developing colon cancer. Therefore, some experts call this kind of colon cancer due to sitting in front of the desk as “desk work cancer”. Sedentary is easy to become “three highs”: What are the “three highs”? High blood pressure, high blood sugar, high blood fat. Especially the modern white-collar workers, sedentary more than 8 hours, almost no movement Palace. Often because of the pressure of work, and life’s chores, and work every day to work overtime. Let their body function is difficult to function properly, and finally lead to hypertension, hyperlipidemia and other diseases. Sedentary prone to pulmonary embolism: Experts tell us that the biggest danger of sedentary is to cause venous thrombosis of the lower limbs. Sitting for 8 hours a day, of which 3 hours in a row without moving, is very dangerous. More than 12 hours of continuous sitting, the risk of pulmonary embolism will greatly increase, especially the elderly in poor health are most vulnerable. Sitting is prone to gynecological diseases: pelvic inflammatory disease, adnexitis. Sitting for a long time can make women lead to pelvic inflammatory disease and adnexitis. The reason for gynecological diseases is also that sitting causes women to be stuffy and breathable, which provides a favorable growth environment for bacteria to breed, leading to gynecological inflammation. Some women find themselves infertile for long periods of time, which may also be caused by Qi stagnation and blood stagnation caused by sedentary. This is because poor blood flow can easily lead to lymphatic or hematogenous embolism, making the fallopian tubes inaccessible. The first time this disease was discovered in a tailor, it was also known as “tailor’s hip”. The sciatic bone is a bone in the hip area of the body. The sciatic tuberosity is the part of the sciatic bone that protrudes. When the body is in a sitting position, the contact surface between the buttocks and the stool or chair is the sciatic tuberosity. At the top of the sciatic tuberosity is a self-protecting device called the bursa. The structure of the bursa is similar to the synovial membrane in a joint and contains bursal fluid. The bursa has a lubricating function when the skeletal muscles encounter collision and pressure. However, as endocrine hormone levels decline in old age, the bursa degenerates as well. There is growing evidence that “sitting” is a deadly behavior that can lead to the risk of obesity, diabetes and fatty liver disease. According to the report, although some people believe that the human body is not designed to sit, but that perception is not true, because if you have to sit, use the appropriate way. To sit healthy, please remember the following six principles: 1, walk from time to time To ensure that you do not continue to sit for too long, it is recommended to take short breaks, about 20 to 30 minutes each time. It is best to get up and walk around, even if it is sitting can also bend, lift the shoulders or deep breath to reduce muscle tension, help themselves to adapt and resume their work posture. 2, do not cross your feet feet is often an unconscious move, although you can relax the muscles, but will limit the blood flow in the other leg, pelvic weight, the center of gravity will also be distributed to the other leg, causing the crestal bend. Experts encourage people to cross their ankles, rather than knees crossed, which is very helpful to the body’s adjustment and blood flow. 3, the posture of the arms 90 degrees or slightly more angle is the ideal bending state of the elbow, for the action of encircling their arms on both sides, you can achieve the effect. Chronic compression of the wrist nerve will lead to carpal tunnel syndrome, which causes hand tingling and pain situation, so it is recommended that people who often use the keyboard, adjust the armrest of the chair can help improve the discomfort. 4, maintain the distance and angle in order to reduce fatigue, the middle of the computer screen is just level with the user’s chin, the distance between the two to maintain about 14 inches, if the computer is placed too far away is not suitable, because the body is easy to lean forward, resulting in crestal dislocation. Many people will put the computer screen on the desk position, resulting in the keyboard in front, the screen is on the side, the body long-term tilt and twist, will lead to more serious problems with the intervertebral discs. 5, to avoid body tilt How to see if you are sitting correctly? Can be compared to the posture of driving, when sitting in the driver’s seat, put your hands on your thighs to keep your body not twisted, hunched or skewed; in driving, we will not to the head leaned forward, reaching to the windshield in front of the car, but strangely enough, we see many people using computers, such a posture, short-term although the impact on the body is not obvious, but over time will be injured. 6, the use of adjustable chairs because everyone’s body type are different, the chair is best to do the adjustment according to the proportion of personal needs and curves. It is recommended to adjust the height of the chair in the office, so that the feet can rest flat on the floor, the thighs should also be parallel to the floor and desktop, the ideal situation is the back of the chair should be close to the back and keep the tilt 90-120 degrees, when looking at the computer screen, you also need a high-backed chair to support the head and neck. Suggestions: In order to physical and mental health, do not sit still to play chess, play mahjong. Older people should not sit at home behind closed doors. Where the work needs to be sedentary people, not only to pay attention to maintain the correct sitting posture, and once preferably not more than one hour in a row, work in the middle of every 2 hours should be at least 10 minutes of interval exercises, or stretching, or free to walk around to stretch the limbs, to relieve fatigue.
