How Important Is The Chair?

人气:115发表时间:2020-11-04

     The chair is not only a tool for rest, but also a "companion" to work and study. It is also a symbol of one's social status! According to the relevant investigation and study shows that: in a person's life, standing: 30 years, asleep: 23 years, sitting: 17 years, so come to sit sitting in our lives accounted for a large proportion, so a Ergonomic chair allows us to sit more comfortable, more healthy life. Investigations have shown that the design requirements of the man-machine seat are as follows: (1) keep the spine healthy and correct curvature; (2) prevent the pelvis from leaning backwards; (3) minimize the pressure on the coccyx and buttock; (4) Provide effective support; (5) reduce and limit the pressure on the leg muscles; (6) provide good support for the pelvis and foot. It is generally believed that the need to rely on the backrest. Now people no longer sit on the chair honestly, they will show a variety of poses, back to give them a chance to rest and relax, but to really relax depends on the back of the chair curve design is reasonable. Before the invention of the chair, human indoor activities to take more squatting, kneeling position. The chair has successfully solved the problem of human body balance. The comfortable sitting posture greatly improves the working efficiency. However, it shifts the load-bearing part of the human body from the knees to the buttocks and the spine. The various health problems caused by the chair also precisely Out here.


      When people are sitting in a chair to work or study, the center of gravity of the human body moves forward and the center of gravity moves forward to tighten the muscles of the neck and back of the human body. Long-term to maintain this sitting position, the muscle group will be stretched, reduced contractility, and gradually lead to head and neck and chest forward, this forward and forced the back of the neck muscle group further stretching, over time, cervical spondylosis and lumbar Come here. Recognizing the importance of a chair makes it "well-targeted" when selecting and using chairs. Need to work long hours desk "office workers" and the elderly, the best choice of headrests, backrests and armrests of the chair, when tired can head and neck and back to the headrest, backrest, hands on Armrests, chair headrests, backrests and handrails can take part of the body and upper arm weight, reducing the chance of muscle strain in the lower back. The height of the chair is best to make the upper body and thighs, thighs and legs angle, both into 85-90 degrees, and feet can be flat with the ground. This will enable the head and pillow, elbow support, back with a back, foot pedal, so that all parts of the body have enough support to reduce the posture of the back muscles and the buttocks, leg muscles, oppression.


      The swivel chair is now also more and more favored by people, in this chair to take something, the whole body can rotate together, help to reduce the back and back fatigue. But the downside of the swivel chair is that people turn around easily, and the chances of getting up and walking are reduced. For office workers sedentary all day long, virtually reduced the chances of activities. It should be noted that, when choosing a chair, to vary. Children's body is in growth and development, the best choice of highly adjustable chair, in order to adjust the height of the chair at any time according to changes in height. But now almost all the tables and chairs in schools and offices are "one size fits all", so many tables, chairs and people do not match at all. Long-term improper chair, no doubt equal to be forced to long-term "insist" bad sitting position, over time can easily lead to children with spinal curvature, myopia and other diseases. As the height of desks and chairs in the office is not "tailor-made," more and more white-collar workers are also suffering from the "torture" of back pain. In addition, the hardness of the chair should also be moderate, too hard chair to sit up uncomfortable, too soft chair is also detrimental to health, especially men, long time to sit over the soft chair, the scrotum is surrounded by compression, can not be normal Temperature regulation, will lead to testicular temperature rise. Testicular spermatogenic cells are very sensitive to temperature, the temperature is too high, is not conducive to the formation of sperm, thereby affecting fertility. Maintaining good posture is as important as choosing the chair that suits you. Sitting on a chair should try to be back straight, the center of gravity will be allocated to the left and right hips and thighs. If you sit on a chair with a backrest, you should try to keep the lower back and backrest close to the backrest on the basis of the above posture, so that the lumbosacral muscles will not be tired. Do not develop the habit of rocking his legs or legs, otherwise it will give the neck, back sustained load, so that the back muscles, ligaments suffered over-stretched for a long time and damaged, causing unexplained low back pain, in addition, seated his legs sedentary, but also Due to squeezing the legs, hinder leg blood circulation.
