Many people have had low back pain, according to statistics, 60% to 80% of people will experience it at different times in their lives. Incorrect sitting posture, lack of exercise and other lifestyles make people “use not practice” and “use not nurture” their low back, coupled with increasing weight, modern people’s low back burden is too heavy. Low back pain plagues three generations According to experts, more than half of the people who come to the pain department now are suffering from low back pain, and there are three generations of old and young people. Among them, back pain in the elderly is mainly due to degenerative diseases such as osteoporosis and arthritis, and is usually accompanied by leg pain. In middle-aged people, back pain is mostly caused by sedentary, improper sitting posture and lack of exercise, and the muscles of the lower back are “overused” but not properly regulated. Back pain among teenagers is also on the rise, and some elementary school students also come to pain clinics, mainly because of heavy school bags and incorrect posture in writing homework. Sitting is more tiring than standing. The first major cause is sedentary and incorrect sitting posture. According to information, when sitting, the force on the lumbar spine is twice as much as standing, weighing 70 kg, the force on the lumbar spine is 140 kg. If the body is tilted forward 20 degrees, the pressure is as high as 200 kilograms, close to three times the weight, so “sitting is more tired than standing”. “The lumbar spine is like a pillar supporting the house, the upper beam is not right and the lower beam is crooked.” Pain specialists say that once the lumbar spine tissue is diseased, it can cause problems such as lower back pain or sciatica. “When you feel a vague pain in your back, the lumbar region has often developed an accumulative injury. In clinical practice, about 35 percent of people with long-term chronic low back pain eventually develop a herniated lumbar disc.” The second cause is lack of exercise. The percentage of back pain is higher among those who do not exercise, “Long-term inactivity decreases the quantity and quality of muscles and the ability to protect the spine.” The third reason is aging. Generally back pain starts from the age of 30 to 40, and as age increases, the degree and frequency of pain will increase. The fourth cause is obesity. “The pressure on the spine is related to weight, so the fatter a person is, the more pressure on the spine. And these people tend to lack exercise and have significantly less muscle protection.” The fifth cause is osteoporosis. Osteoporosis causes changes in spinal thickness, shortening, and problems with stress, which usually makes women’s back pain come earlier and last longer. In addition, arthritis, smoking, stress, and pregnancy can all contribute to back pain. Xi’an Zhongde orthopedic specialist said, “People can perceive just the symptom of pain, but there are a variety of causes of pain.” Eighty percent of people need to correct their sitting posture The survey shows that about 80% of people sit incorrectly to bring back pain to the hidden danger. Wrong sitting posture includes hunching at work, sitting at the front edge of the chair, and reclining on the sofa to watch TV. “The best way to reduce the burden on the back, is to form the correct sitting posture. First, we need a comfortable chair. Chair should not be “too deep”, sit down when the hips can sit full chair, so that the waist and back completely close to the back of the chair; two feet should be able to flatten the ground, so that the knees are the same height or slightly higher than the hips. Next, find a comfortable cushion. Experts say, “The best choice of cushion can fit perfectly with the lumbar spine, the material is a little harder, with a certain support strength.” Finally, always correct the sitting posture. When sitting, lumbar close to the cushion, not “only cushion not lean”. Experts say that the seat cushion is still hunched over, the cushion is virtually useless. From time to time, you may want to pull the chair a little closer to the table or move the computer monitor on the table a little closer. Every hour, be sure to stand up and move for 10 minutes to do some stretching exercises related to the low back. Do this to prevent low back pain: 1, stretching, sunshine can relieve pain daily low back stretching exercises, 10 minutes each time, 2 times a day, to help prevent low back pain. The specific posture is to slowly move the neck left and right, freely shrugging shoulders, and then do two arms open and close the chest expansion exercise. This set of movements can make the spine “reverse” relaxation. The sun can reduce chronic pain in the elderly such as low back pain and cold legs. 2, to the backpack to reduce the weight of the backpack more than 10% of their own weight, it may cause damage to the back. Open your bag and clear out the things that are rarely used inside. If you use a single shoulder, it is best to rotate the left and right, if you use a double shoulder, it is best to choose a wide shoulder strap. 3, don’t sleep too hard bed A recent study found that people who sleep in soft beds are less likely to suffer from back pain than those who sleep in hard beds. At the same time, do not choose too high pillow, if you sleep on your back, do not let the jaw press the chest; if you sleep on your side, do not let the head too bent to the shoulder side. 4, do housework to pay attention to women always bend over when doing housework, sweeping, mopping often side force, so it is easy to make the back under more pressure. It is recommended to do a while housework must take a break, the same action do not last too long. 5, if the pain for more than a month to seek medical attention experts recommend that when the pain for more than a month to seek medical attention, and it is best to go to a professional pain hospital examination and treatment, because the back pain is not only the cause of the bones, but also includes the muscle tissue and nerves of the waist, as well as the blood pain-causing substances, only then can patients get a comprehensive examination and treatment.
