Why does the waist ache when people sit for a long time?

Many people, especially those who work in the office for a long time, often suffer from chronic neck pain, low back pain and leg pain. How to prevent these neck, waist and leg pains? It is recommended that you sit 1 hour and get up for 5 minutes. Sitting in the office for a long time has neck, waist and leg pain. Let's talk about the waist first. Low back pain is a common disease in people's work and life, especially those who work in a sitting position for a long time, especially those with lumbar muscle strain. They constantly seek medical advice, traction, massage, acupuncture, painkillers and bed rest ... but most people are still repeating the cycle of pain-treatment-improvement-pain. What causes low back pain to be cured for a long time? Is there a good treatment? Low back pain is "the pain in the world". In the United States alone, the economic loss caused by low back pain is as high as $654.38+000 billion a year, while in Germany it is 20 billion euros. According to western statistics, 80% of adults will experience back pain at least once in their lives, and 7% of them will turn into chronic low back pain when they reach 1 1%. The waist should be strong enough to support the weight of the trunk and flexible. Around the waist, there are two different muscle systems working under the command of nerves. People can see that the back muscles are very strong, just like Optimus Prime, which mainly controls the output. In the body, there is a group of "local stabilizing muscles" near the lumbar spine. These muscles are not strong, but they are responsible for protecting the stability of the lumbar spine, so that when you bend over, the five lumbar vertebrae will not move back and forth or sway from side to side. In many cases, low back pain is caused by weakness, strain, atrophy and dysfunction of locally stabilized muscles. Lumbar muscle strain is a chronic injury to lumbar muscles, intervertebral discs and ligaments. The reasons can be summarized into three types: first, long-term bad working posture, such as bending over, carrying heavy objects on one shoulder, or habitual posture, makes the lumbar muscles in a state of traction for a long time, resulting in cumulative strain degeneration and soft tissue fatigue, leading to low back pain; The second type is congenital or acquired deformity of lumbar spine, long-term bedridden after lumbar trauma, and long-term fatigue of lumbar muscles. Third, the acute injury of lumbar soft tissue is not handled properly. People who work in the office for a long time are most likely to suffer from lumbar muscle strain, which requires them to change their posture frequently and correct their bad posture at work. At ordinary times, it is necessary to strengthen the exercise and protection of back muscles and intervertebral ligaments. Before exercising or lifting heavy objects, you should be prepared to prevent your waist from being sprained by sudden exertion. I often take part in physical exercise, play Tai Ji Chuan and do aerobics. Conducive to preventing lumbar muscle strain. If you hurt your neck with a laptop for a long time, talk about your neck. In the outpatient department, many patients with cervical spondylosis did not see a doctor in time. If your cervical pain has not improved for more than two weeks, and no abnormality is found through X-ray examination, it is mostly due to cervical muscle dysfunction. Dysfunction of spinal muscles means that there is something wrong with the muscles that protect the spine. It's like a person who is not familiar with driving, and the car will break down faster. Through self-regulation, most cervical pain will recover within two weeks. If it takes more than two weeks, you must go to the hospital in time. Financial personnel, teachers, writers, graphic designers, IT workers, drivers, etc. They all belong to the high-risk group of cervical spondylosis, so we should pay attention to the usual health care, change posture every 1 hour at work and stand up for 5 minutes. Long-term use of notebook computers is very harmful to the neck. Those who usually use a laptop can put two books under it. The thickness of the book is controlled by yourself. As long as you sit up straight, the line of sight is basically flush with the top of the monitor. In addition, the notebook or computer monitor must be placed in a direct view area. If you always twist your body or look at the computer with your neck crooked, it is easy to cause neck pain. There are also many people who often work at their desks, such as teachers and financial personnel. When choosing a desk, it's best to choose an inclined desk, or make a 30-45 degree inclined plate to support it on a plane, which will make them feel more comfortable. I also want to mention the standing posture of middle-aged people. Many middle-aged people always "bow their heads" when standing. Needless to say, they often have problems with their cervical vertebrae and their necks unconsciously lean forward. At this time, the muscles outside the neck have been working hard. When they are tired, their necks ache. Therefore, don't think that practicing standing posture is only for children or dancers. Middle-aged people should first keep their heads straight and their shoulders slightly open back. Remember not to move your head back, but move your neck back and keep this position for a while. It may feel a little awkward at first, but as long as you stick to it for two or three weeks and form a good posture, your neck will be much more comfortable. Climbing stairs and mountains will aggravate knee arthritis. Finally, talk about the knee joint. Lao Zhang has knee arthritis. Others say that if he has arthritis, the more painful he is, the more positive he is. So she made an appointment with her partner to climb the mountain together, but the next day after climbing back, Lao Zhang's knees could not move. Why is this? Knee arthritis is a common disease in middle-aged and elderly people. The survey shows that the incidence of knee arthritis in people over 55 years old is over 60%. Characterized by pain and swelling of the knee joint. It is necessary for arthritis patients to exercise actively at ordinary times, but they can't feel pain after exercise or after getting up the next morning. If it still hurts the next morning, it is either excessive exercise, uneven exertion and unequal exercise methods. The wrong way of exercise will often aggravate the condition, and hospitals often accept patients with knee arthritis caused by excessive outdoor activities such as mountain climbing. In fact, patients with knee arthritis can't move, can't move blindly, and can't resist pain. Because excessive activity will lead to joint strain, too little activity will lead to premature aging. People with knee pain after going up and down stairs or sitting for a long time should try to reduce the number of going up and down stairs and climbing mountains. When you have to go upstairs and downstairs, you must master certain skills. When going upstairs, step on the painless leg, and the painful leg will follow, so as to avoid stepping on the painful leg first; On the contrary, when you go downstairs, you should get that sore leg first. If the pain in your legs is severe, you can go up and down the stairs sideways to relieve the pain appropriately. When sitting, do more such actions, that is, try to straighten your legs or take turns to straighten your legs. Patients with knee arthritis can choose swimming, walking, cycling and other sports with light joint load as appropriate. In addition, try not to get hurt or catch a cold, supplement calcium properly, usually use knee pads and wear flat shoes. Obese people need to lose weight. Once there is pain and swelling, you should go to the hospital for treatment to relieve the symptoms.
