How important is an office chair that fits the lumbar curve of the human body?
You work 8 hours a day. How are your back, shoulders and neck? Long-term sitting and poor sitting posture are one of the "culprits" of lower back muscle injury, lumbar disc herniation, and neck and shoulder pain. According to relevant data released by the National Health Commission, the number of patients with lumbar spondylosis in China has exceeded 200 million. The detection rate of lumbar disc herniation among young people aged 25 to 39 is as high as 13.93%, ranking steadily among all age groups. the first position of the segment. Young people aged 25 to 39, as the "main force" in the workplace, are plagued by health problems. This phenomenon has also attracted more attention.
For professionals, maintaining the same posture or sitting in a bad posture for a long time will often cause the spine to be in an abnormal curvature state for a long time, which will pose a serious "threat" to health over time. This is not just an individual case, but an ongoing health crisis that requires us to think carefully and take active measures to improve it, such as choosing a comfortable office chair to relieve back pain.
It is reported that the human lumbar spine curve is a naturally formed physiological curvature of the lumbar spine, and its existence has important physiological significance. The main manifestations of this aspect are: the human lumbar spine curve can increase the elasticity of the lumbar spine, making the lumbar spine more stable when bearing gravity, and is more conducive to maintaining the body's balance. At the same time, the natural physiological curve of the human lumbar spine helps to disperse the vertical pressure on the spine and reduce the pressure and friction on the lumbar spine.
Generally speaking, a proper lumbar curve can help maintain the balance of the spine and reduce waist fatigue. Excessive curvature or abnormal lumbar posture may increase the burden on the waist, so maintaining a proper lumbar curve is one of the keys to maintaining spinal health.
The lumbar spine is an important part of the human spine. The importance of an office chair that fits the curve of the human lumbar spine is that it can provide ergonomic support and comfort, and effectively relieve the pressure and discomfort caused by long-term sitting. This type of office chair should have the following functional designs:
Lumbar support: The lumbar support is one of the core parts of the office chair. It supports the waist, helps users maintain a correct sitting posture, effectively reduces the pressure on the lumbar spine, and relieves back pain and other problems.
Specifically, when a person is in a standard standing posture, the lumbar spine will show a normal physiological curvature, and the person will feel very relaxed in this state. Because the waist core muscles and abdominal core muscles maintain a balanced force in this form, there is no excessive stretching or contraction. But when we sit down, if there is no suitable lumbar support, the pelvis will tend to tilt backward, the lumbar spine will change from lordosis to kyphosis, and the force balance of the waist and abdominal core muscles will be broken. Therefore, the lumbar support system of the office chair can maintain the natural lumbar spine shape of the human body and reduce the pressure on the lumbar spine and pelvis, thereby helping the human body better avoid lumbar muscle injury, lumbar disc herniation and other problems.
Back support: The ergonomic chair back design can disperse the pressure on the back muscles, prevent scoliosis, and reduce the risk of spinal diseases.
At the same time, the adjustable recline angle of the chair back can evenly distribute the pressure on the human sitting bones and spine. If you want to sit comfortably, the recline angle of the chair is very important. Especially for professionals who need to take a lunch break, the greater the recline angle of the seat, the less pressure on the spine and the more comfortable the lunch break will be.
Not only that, the chair back also has a supporting function. If the support force is too small, a person with a heavy weight will easily fall; if the support force is too strong, a person with a small weight will have a hard time leaning back. Therefore, office chairs must have good mechanical balance properties so that users of different weights can feel the silky and light sitting feeling of "relaxing back and effortless getting up".
Seat design: The depth and width of the seat should be moderate to adapt to the needs of users of different sizes and provide more personalized support and comfort. Because seat designs that are too shallow or too deep may lead to incorrect sitting postures, which may affect the user's spinal health.
In addition, considering the office sitting posture of working professionals, it is recommended to choose a seat with 5 to 10cm of space between the edge of the seat and the back of the knees. Because if the seat is too far forward, it can put too much pressure on the back of your knees. This reasonable seat depth setting helps ensure a comfortable sitting posture while reducing knee discomfort, providing better support for long hours of office work.
Armrest design: The armrest design of the office chair cannot be ignored. As a support point for the arm, it allows users to rely on it when typing on the keyboard or reading. In particular, the adjustable armrests can adjust the height and angle according to the user's needs in multiple scenarios, providing more comprehensive support and assistance, thereby effectively reducing the burden on the shoulders and arms.
All in all, the harm caused by prolonged sitting must not be ignored. Choosing an office chair that fits the lumbar curve of the human body is crucial for office work and study. In order to "transfuse life" to key parts such as the "old waist", "buttocks" and "arms" and maintain the health of the spine, please choose a high-quality chair for your lumbar spine and take full care of it!
