The most suitable work companion for workers who sit for long periods of time
Working in the Huli Internet industry, daily work is inseparable from computers, and it is normal to work overtime when you are busy. The "occupational disease" of long-term sitting is a problem, and the body often suffers from a lot of discomfort due to long-term sitting.
As a sedentary worker, what "occupational diseases" do you often encounter?
As a bricklayer who has not left the Internet industry for more than ten years, he spends most of his time in front of the computer desk every day. He often suffers from various minor problems and has few good places. He is comparable to Osamu Tezuka. "Dororo" in the pen.
Among them, the most common problem is the cervical spine. The cervical spine is the "Achilles' heel" of workers who sit for a long time. Many problems will occur when the neck is sitting for a long time, bowing the head, or stretching forward, such as: Cervical spondylosis, neck pain, migraine, brain fog and forgetfulness, dizziness and nausea, neck and shoulder pain, insufficient blood supply to the brain, etc.
In addition, after sitting for a long time, problems such as lumbar disc herniation and back pain often occur. Once the waist starts to hurt, I will quickly wear a lumbar support to prevent the waist from bending forward and backward and twisting left and right, and use the support plate in the lumbar support instead. To support the lumbar spine, wait until the nucleus pulposus of the lumbar spine slowly returns to its original position before removing the lumbar support. Otherwise, the waist injury is likely to become more serious. Once the injury is severe, the whole person will have difficulty moving and have to put his hands on his hips when walking!
In addition, due to long-term work with arms hanging in the air, conditions such as shoulder pain and carpal tunnel will often occur. If they occur once or twice from time to time, they will greatly affect normal work and life.
In order to solve these problems, many "protective gears" have been purchased, including neck braces, lumbar braces, cervical spine pillows, wrist braces, etc. However, each type of protective gear is only for emergency use and cannot solve all problems once and for all. It's often the case of "pressing down the gourd and letting the gourd float up". It doesn't hurt here and it hurts there!
Based on the above injury experience, in fact, in addition to eye fatigue, occasional tinnitus and other problems. Other problems are directly related to poor sitting posture and working for too long! Sitting for long periods of time is the "root of all evil" that affects the health of Internet workers.
Therefore, in order to resist the harm caused by prolonged sitting and save the health and career of wage earners. It is really necessary to buy a "physical plug-in" that is suitable for sitting for a long time and relieves the damage caused by sitting for a long time - an ergonomic chair!
How do ergonomic chairs help "sedenters" relieve injuries caused by sitting for long periods of time?
Because ordinary chairs have very limited protective capabilities. Sitting in an ordinary chair for a long time often results in the neck and lumbar spine not being supported, the continuous tightness of the muscles not being relaxed, the shoulder and wrist joints being under pressure for a long time, and the lower limbs being immobile for a long time causing numbness and varicose veins. question.
Compared with ordinary chairs, the support of ergonomic chairs is very comprehensive. It is quite like the movie "Tomorrow's War", which created a set of auxiliary support "exoskeleton" for workers who sit for a long time. With its help, it can help people maintain good sitting posture, disperse body pressure, and relieve injuries caused by prolonged sitting! Let’s take a look with Brother 4 below!
The human spine is more like a spring, with two forward bends at the cervical and lumbar vertebrae, and two backward bends at the thoracic and coccygeal vertebrae. This "spring-type" structure allows the spine to become a shock absorber and stabilizer for the human body. device! It can filter the vibrations transmitted from the ground when walking and running, so that humans can walk and run upright without being shaken and dizzy.
However, the conditions of each position of the spine are also different. The structure near the thoracic vertebrae has auxiliary support from the ribs, and the structure near the tail cone has auxiliary support from the pelvis, making these two parts less likely to have problems.
But the situation of the lumbar spine and cervical spine is very different! Unlike the stable support structures of the back and hips, the human waist and neck have extremely high flexibility, allowing them to flexibly raise their heads, lower their heads, and turn their heads. Bending, twisting and other movements.
However, the consequence of extremely high flexibility is that the cervical spine needs to rely on a few small bones to support the weight of the entire head; and the lumbar spine also has several bones to support the weight of the entire upper body.
Such a body structure puts great pressure on the cervical and lumbar vertebrae, causing the nucleus pulposus to bulge and squeeze inward into the spinal cord, causing problems such as limited movement, insufficient blood supply, and numbness of the limbs!
① Ergonomic chairs can help people maintain good physiological curvature of the spine, assist in spinal support, and prevent cervical and lumbar vertebrae from protruding!
The backrest of a traditional chair is designed to be straight up and down, with no support for the forward bending of the neck and waist. You need to maintain a straight and upright sitting posture throughout the entire process to avoid excessive local stress on the spine caused by the "leverage principle" due to tilted sitting posture.
The ergonomic chair has a headrest support for the neck and a lumbar support design for the waist. The back of the chair is also designed to provide support for the neck and waist.
Neck Support Judging from the experience of using neck braces and cervical spine pillows in the past, the headrest of the ergonomic chair mainly shares the pressure of the cervical spine in two aspects. On the one hand, it supports the weight of the head and partially bears the weight of the cervical spine. On the other hand, it is placed on the back of the head near the lower cervical spine to support the cervical spine curve and help the cervical spine maintain a forward physiological curve.
②The ergonomic chair can disperse the body weight, reduce the stress on the spine, and relieve fatigue from sitting for a long time!
Just from the perspective of the body weight borne by the spine, when sitting upright, all the weight of the human upper body is supported by the spine. When you sit on an ergonomic chair and lean back slightly, part of the human body's gravity is supported by the chair, which greatly reduces the weight borne by the spine. When the "lying" mode of the ergonomic chair is turned on, the spine can take a break and get a chance to relax.
The backrest of an ergonomic chair looks like a person sitting on a sofa. The wider the size of the backrest, the larger the contact surface between the person and the backrest, the stronger the wrapping feeling, and the more comfortable the actual body feeling. When the human body leans on the ergonomic chair, the body pressure can also be well released. It reduces the accumulation of fatigue in various joints of the body caused by long-term sitting, and can better meet the actual needs of sedentary workers.
③The ergonomic chair can provide a "lying flat" rest environment, relieve muscle tension, and quickly restore energy.
As a worker who often works overtime, it’s really hard! I usually go out very early, and sometimes I have to work overtime at night. When you are busy, you spend almost half of your time at work, so taking a lunch break is very important! Good rest quality can help people quickly restore physical strength and energy, release pressure on various parts of the human body, allow the human body time to repair itself, and avoid fatigue damage to the spine and other locations.
④The ergonomic chair has a ventilated and breathable mesh design to avoid prickly heat and skin redness and swelling caused by sweating in summer.
Compared with traditional sponge cushion and leather chairs, ergonomic chairs adopt a mesh design, which is comfortable and breathable. In the hot summer, prickly heat will not occur due to sweating at the position in contact with the chair.
⑤ The ergonomic chair is elastic and non-compressive, making it easier to move the body and avoid varicose veins in the lower limbs.
Compared with benches and wooden chairs, ergonomic chairs use an elastic mesh design. The human body and the seat cushion are in flexible contact, unlike traditional chairs, which are rigid contacts. Therefore, the blood vessels in the legs are not oppressed, so that the legs will not suffer from long-term fatigue. Sitting numb. The cushion design with downward curved edges avoids direct pressure on the legs when sitting on the chair and prevents the problem of numbness caused by sitting for a long time.
The seat cushions of ergonomic chairs support seat depth adjustment, and the position of the seat cushion can be adjusted forward and backward. In addition, among the seat cushion sizes of several chairs, Gu Yongzhi’s seat cushion is the largest, especially wider laterally. Can provide a more dispersed and comfortable seating experience.
It adopts a four-level safety air column that can be lifted and lowered. The height of the chair is adjustable, ensuring sufficient space for leg activities. Frequent changes in leg posture can avoid varicose veins in the lower limbs.
The chassis adopts a lever + wire control adjustment chassis, and all adjustment functions are located in the area controllable by the left and right hands under the seat cushion. In addition to the adjustment at the bottom of the seat cushion, there are many adjustment functions located on the chair back and other locations.
⑥The adjustable armrests of the ergonomic chair can provide elbow support and reduce pressure around the shoulders and wrists.
When typing, the pressure is mainly borne by the shoulder joints, elbow joints, and wrist joints. If your elbows are hanging in the air while typing, your shoulder and wrist joints will bear greater pressure, leading to problems such as frozen shoulder and carpal tunnel. Due to a lot of daily typing, I often get blisters on my wrists. Later, in order to avoid such things, I also bought protective equipment such as wrist guards and gaming gloves.
It's different with adjustable armrests, where you can rest your elbows and forearms while typing. This can disperse the pressure very well. Since the elbows and forearms are similar to "spherical" and "cylindrical" structures, when choosing armrests, it is recommended not to choose angular armrests. It is recommended to choose armrests with softer lines, which can increase the elbow and small arms. The contact area between the arm and the handrail should be adjusted to avoid "shocky" contact with edges and corners.
⑦Ergonomic chairs are often used for many years when purchased once. Durability is very important!
Ergonomic chairs are often used for many years once purchased. Therefore, the workmanship materials and the sturdiness of the frame are very important.
Using pure metal five-star base, this material design makes the base of the ergonomic chair more stable and will not break easily like nylon feet. As for the wheels, they all use flexible and silent wheels, so there won’t be much of a problem in terms of wear resistance.
Summarize:
Over millions of years, humans have learned to walk upright through evolution, freeing their hands to use tools. The body has been developing in a direction more suitable for standing on two feet and running.
However, with the development of science and technology, in just a few decades, due to the widespread popularization of computers, a large number of jobs have shifted from manual labor to mental work. Traditional manual labor and combined physical and mental work have suddenly become long-term tasks. Sedentary office mode for computers.
Obviously, our bodies have not adapted to this change from standing to "sitting". For sedentary people, especially those like me who need to work in front of computers for long periods of time, simply relying on basic adjustment methods such as adjusting sitting postures, standing and walking frequently, and standing up to move muscles and bones is no longer enough." Labor Protection "Demand. However, the nature of work determines that it is impossible to completely leave the computer to work, thereby avoiding sitting for long periods of time.
"If you want to do your job well, you must first sharpen your tools." With the emergence and popularity of ergonomic chairs, people have finally found a solution to the "injury caused by prolonged sitting." It allows us to obtain healthier cervical vertebrae and spine, improve problems such as dizziness, mouse hand, frozen shoulder and leg varicose veins, and gain better energy and physical endurance.
