Office Chair Health Method
At present, the "office chair" is working at home and the game is getting longer and longer. The office space with stereotypes and equations is no longer able to meet people's needs. Therefore, there are more and more desks and chairs that pay attention to individual development and pay attention to humanization, such as various colors, unique shapes, and convenient use. But only the shape or only the function is not enough. Whether at home or in the office, the design of the office space must be based on the rationality of rationality, that is, professional words and personalization.
Many people choose the height of the office chair that is not up to standard, so that the body can not be freed from back pain. So, how can I adjust the office chair to the "best state"? First adjust the desk or workbench to the right height according to the nature of the work. Because different desk heights have different requirements for the placement of the seat, and sometimes even a seat is required. Once the height of the desk is fixed, the height of the seat can be adjusted by using the desk and body height as a "reference".
1. Try to choose an adjustable function
A good computer chair should not only be comfortable, but also have a high degree of freedom in both the vertical and horizontal directions, that is, the adjustable range is large.
Choosing a comfortable seat is crucial. The good seat has a double pneumatic function, which can adjust the height of the chair and adjust the pitch angle of the seat back.
When shopping, you can sit down and feel whether the back of the chair is soft and moderate, whether the curve of the back of the chair fits the curvature of the human spine, fully support the back, and whether the waist can relieve the excessive pressure load on the back. Make sure the seat is seated correctly and the seat is wide and thick. Comprehensive support can not only reduce the impact of the body's weight when sitting down, but also relieve the pressure on the buttocks during long-term work, relax the body and mind, and improve work efficiency. At the same time, we must pay attention to the selection of the casters: whether it is safe and smooth, whether it can rotate freely on the carpet, whether the plastic texture of the roller is too hard to damage the floor.
2. Method for identifying the quality of computer chairs
Poor quality computer chairs are often not only harmful to health, but also easy to damage, and ultimately economically not cost-effective.
A. Observe the cushion.
The general computer chairs are sponge cushions. The good cost of a good cushion is high, so some merchants make a fuss about the cost of reducing the cost of the sponge, or the strength of the material. A good cushion is generally thicker and has a curved curve that fits down to fit the person's ass. In addition, good cushions have better elasticity. If the seat cushion is thin, it is uncomfortable to sit up. If the seat cushion is thick but not elastic, the merchant may have used poor materials. So you must keep your eyes open when you buy a cheap computer chair.
B. Sitting feeling.
If the design is reasonable, the chair generally has a comfortable sitting posture, and the seat cushion portion has good acceptance and inclusiveness, and does not feel uncomfortable.
C. The backrest should be reliable.
Some chairs have loose backrests and make noise when they are leaning back. Such chairs are easily damaged.
D. Try to shake left and right
If the overall structure of the chair is unstable, it is easily damaged.
Try to put it on the armrest, whether it feels comfortable.
F. gas rod
If you buy a swivel chair, try lifting the swivel chair and feel that some of the lifting process is smooth. If you feel dry, the gas bar is not good.
G. Freedom function
Some chairs have a reclining function, try to open the free function, and feel that you can rest assured that "free".
F. Turn the chair over
Watching its hidden structure, if it is found to be rough or even rusty, it is a poor quality product.
3. Put a cushion to keep sitting
The cushion can really relieve the people with lumbar muscle strain, but there are also a lot of stress when using the cushion. First of all, the cushion must be placed at the waist, and it is not effective to put it on the back. This is because the normal human body has three physiological curvatures. Because of physiological requirements, they do not grow in a straight line. The thoracic vertebrae are convex, and the cervical and lumbar vertebrae are convex forward. From the side, the spine is like the connection of two S. Due to this physiological feature, the waist and back cannot be placed in the same plane.
Therefore, when sitting on a computer chair, if you put a cushion on the waist, you can effectively support the waist, maintain the flexion of the lumbar spine, balance the pressure of the lumbar spine and lumbar muscles, reduce strain, increase comfort, prevent and improve the lumbar spine. Discomfort is good for stabilizing the spine.
Secondly, the thickness of the cushion should be appropriate. Can not be too thin and too soft, so that it can not lift the waist, not too thick and too hard, too thick may cause excessive flexion of the lumbar spine, and too hard will be uncomfortable. The cushion can be placed behind the waist during the selection. If the cushion still feels comfortable after ten minutes, the thickness is suitable. If the back is tired or even painful, the cushion is unqualified. Furthermore, people who already have lumbar disc herniation and lumbar spinal stenosis should pay more attention to the comfort of the cushion.
4. Correct posture to prevent occupational diseases
Maintaining a good posture is the best way to prevent occupational diseases. The correct operating posture includes the following five points:
A. When operating the computer, make sure that the wrist is straight when using the keyboard, that is, the angle formed by the wrist in the four directions of up, down, left and right is as small as possible, neither leaning nor folding. It is neither twisted to the left nor twisted to the right, so as to ensure that the wrist is always relaxed and not easy to fatigue.
B. What is the angle of the elbow joint when operating the computer? Is the angle between the inner surface of the upper arm and the forearm? Is the hole greater than 90 degrees? The hole is the arm that looks as straight as possible, to avoid the elbow nerve being squeezed.
C. The requirements for operating the mouse are similar to those for operating the keyboard: when placing the hand on the mouse, try to ensure that the wrist is straight and the upper arm and elbow should be as close as possible to the body, giving the wrist more flexibility.
D. Make sure the back is straight when sitting on the computer chair and the feet can be placed flat on the ground. If the back is not straight, it will easily cause the spine to deform, and the height of the seat is not suitable for causing the legs to be over-flexed or over-extended.
E. When sitting in the office chair, the neck should be as straight as possible, and the whole body should feel relaxed.
