Nowadays, many people need to sit when working, often facing the computer, sitting for a whole day, feeling back pain, and can hardly stand up straight...Let's talk in detail about how to "talk while sitting without back pain".
Emphasis
When people sit, the weight of the upper body is concentrated on the waist, causing the pressure on the lumbar intervertebral disc to be at least 150% of that in the standing position.
A suitable chair should have a backrest, armrests, and wheels.
If you have to sit for a long time, you should also pay attention to maintaining a correct sitting posture.
Most people need to sit when working, and more and more people find that the time they sit every day has exceeded the time they lie down.
It is an indisputable fact that sitting for a long time hurts the waist. Therefore, on the one hand, we should try to avoid sitting for a long time as much as possible, and on the other hand, we should learn to use some skills when we have to sit for a long time to minimize the damage to the spine.
There should be "feeling-friendly" armrestsThe armrests have similar functions to the chair backs, and can also effectively share part of the load.The armrests should be of a suitable height, and it is best to allow the upper limbs to rest on them in a relaxed manner, without pulling the soft tissues such as the muscles and fascia of the neck and shoulders or the chest and back, waist and back due to being too high or too low. When we sit and work, we often don't need armrests, so we can choose retractable armrests.Have wheels that "turn as you like"When you sit and work, you may need to turn around at any time to get information or communicate with people, and wheels come into play at this time. Without wheels, people can easily generate shear stress on the lumbar spine due to turning. With wheels, this action is much safer.In addition to choosing a suitable chair, you must also adjust your sitting posture
In daily work and life, it is unrealistic to rely on "consciousness" to maintain a good sitting posture. Many people can sit very standard when they start working, but after a period of time, the good posture can't help but "collapse".When sitting and working, the adaptation of the table-chair-computer screen is very important.The center of the computer screen should be basically flush with the line of sight; the chair should be able to be stuffed under the table, so that the front of the body is one fist away from the edge of the table when the human body is in a sitting position.Only by adjusting the environment and "limiting" us to a good position can people involuntarily maintain a good posture when sitting. In order to adjust a good sitting office environment, computer stand, wireless mouse, keyboard, lumbar pillow, etc. can be included in your shopping list.
