Workers should not only be reconciled and reluctant, but also have care for their own health。Society is everywhere in the "roll", in addition to overtime or overtime every day, people who fall due to overwork abound, whether you are a social elite, or an ordinary worker, and whether you have money or not.
According to statistics, more than 6 percent of office workers sit for 6 hours a day, and more than 28% of office workers sit for 8 hours a day. So what's the harm of sitting every day?
Long-term sedentary can causeThe strength of the lumbar spine muscles is weakened, and lumbar spine instability increases the chance of a herniated disc in the lumbar spine。Many sedentary people have low back pain, lumbar muscle strain, lumbar disc herniation, back pain and other problems. For example, drivers who drive all year round are normal because they don't have a few waists because they sit for a long time.
Discomfort in the lower back is not necessarily a problem with the disc itself;It may also be that there is a problem with the lumbar spine, sacroiliac bones, muscles, ligaments, fascia。For example, when stretching the waist, there are three muscles to cooperate, such as the gluteus maximus muscle is strained and weak, then the waist will be sore, and the problem appearsSacroiliac bonesAbove.
The cervical, thoracic, lumbar and sacral vertebrae are a whole and are dynamically related to each other. Among them, the sacrum is connected to the lumbar vertebrae, the lower part is connected to the coccyx, and the two sides are connected to the ilium, and the sacroiliac bone is the foundation of the spine. Improper sitting posture, prolonged sitting, and poor straining behaviors can all causeLumbar facet joint disorders, orSacroiliac joint misalignmentetc., which in turn affect the discomfort of the lumbar spine and even the disappearance of the lumbar spine curve. As shown in the figure below, it is a disorder of the sacroiliac joint, which causes low back and back pain, and in severe cases, scoliosis.
Changes in the angle and position of the sacroiliac bone can cause changes in the pelvis, and pain is usually manifested in the lower back. There are also many behaviors that affect lower back discomfort:
If women wear high heels, it is easyAnterior pelvic tilt, triggering spinal stenosis, as wellThe physiological curve of the lumbar spine becomes larger, causing lower back pain.
Such as long-term desk work,The lower back is arched, the abdominal muscles are contractile and weak, and the psoas muscles need more force to compensateIt's easyPosterior pelvic tilt, stretching ligaments,The curvature of the lumbar spine becomes smaller, which can also cause pain in the lower back.
If you often cross your legs, it's easyLateral pelvic tiltWhen walking, the legs are long and short, scoliosis breaks through the fibrous ring, and the nucleus pulposus is easy to protrude from the side.
If you sleep on your side for a long time, it is easy to sleep on one sideRotation of the ilium, ligament stretching, can also cause lower back discomfort.
Whether it is an imbalance in the sacroiliac joint or an imbalance in the lumbar spine, it is best to have medical intervention first. Small problems can be recovered once or twice, and big problems should be treated as soon as possible, which is fundamental.
I have a lot of pressure at work, sometimes I sit for hours at a time, and my back will be uncomfortableThere's no way, Party A's father's money is not easy to earn. However, I was more sorry for my life, and I had some slight pain in my lower back, so if it was not relieved for a few days, I would go to the hospital to "intervene" to allow the overstretched muscles and ligaments to be repaired and restored.
By the way, I forgot to tell you that I am also a low back pain patient, and it has been a herniated disc for more than 20 years. Lumbar L4-5 protrusion, sacroiliac joint disorder, nerve radiating pain, inability to straighten the waist, etc., these have been experienced. Later, it was through such "interventions" and daily maintenance that he did not fall ill for many years.
From what I've observed, if people who don't exercise go for an MRI, few of the spinal muscles may be normal. In particular, the degenerative changes in the lumbar spine, the older you get, the more serious the condition, but some people have symptoms and some people don't, and they are getting younger and younger. The problem on the waist is divided into three points, and the seven points are raised, and only ** is not maintained in vain
Raising in your free time: Five-point support, train core strength, strengthen muscle stability;
Maintenance at work: You need to rely on a good chair to take care of your old waist;Although the work is tiring, it has to continue, otherwise you will have to roll up and leave.
At the same time, I would like to advise you that people who have a lot of work pressure and little time to exercise really need a good chair. Time will tellWhen I was young, I didn't know that the lumbar spine was expensive, and the old people were crying when they supported their waists
Waist discomfort, after talking about appropriate medical "intervention" and maintenance in free time, let's talk about which chair on the market is better to "nourish the waist". At present, there are roughly three types of chairs in the domestic market:Lumbar support, sacral support, and lumbosacral support；**From low to high, there are suitable people.
At present, most of the chairs in China are "lumbar support", emphasizing".Top waist feeling"It's this kind of chair. Whether it is a fixed lumbar brace or an adaptive lumbar brace, their mechanical action points are on the L3-5 segments of the lumbar vertebrae. Moderate strength is appropriate, and a strong top waist may not be really good.
Slim people are usually more sensitive to pain, and a waist chair is not used. For people who wear high heels for a long time, the chair with a top waist is also not used, which will aggravate the anterior pelvic tilt. People who sleep on their side for a long time have unilateral iliac rotation and are not suitable for a waist chair. There is also sacral joint imbalance, lumbar muscle strain, lumbar disc herniation should not use a strong support chair, the squeeze force is large, and the muscles and ligaments will not adapt. Unless you're bigger, use a top-waist chair
Case 1:
Looking at the picture above, the upper body is slightly leaning on the back of the chair, and the lumbar support pushes you forward, while there is still a gap between the back and the back of the chair, and the weight of the upper body is all piled up on the lumbar spine. Is this your old waist still comfortable?Will you sit for a while?Will the muscles be slightly sore?Is it possible for the physiological curve to change?
When the lumbar brace is compressed again when the back rests, the support force is stronger, and the waist is more obvious. Not only that, but the lumbar brace will also move up, and it may also touch the ribs of the thoracic spine, which will cause discomfort in the thoracic spine. Therefore, you should be cautious when choosing a chair with a strong waist, unless you are obese and can hold it down.
Case 2:
Looking at the picture above, it is still the same person, leaning back slightly, and the fit of the waist and back is very good. The lumbar support pillow is soft and can be moved back and forth, and there is a knob to manually adjust the strength of the lumbar support, and the lumbar back system of this chair is more comfortable.
At this time, the fit of the lower back is still good, the elbow is also supported, and the lumbar support is not moved up to compress the thoracic spine.
Although the lumbar support of this chair is good, it is also disadvantageous, and the seat cushion is highly elastic, which is not conducive to pelvic stability when sitting with a large weight, and it is also easy to dent the seat surface.
, sacral support
In the above 2 cases, if the sacroiliac bone causes soreness and pain in the lower back, the use of them does not improve significantly. Because neither chair takes care of the base of the spine - the sacroiliac bone.
The chair in the picture above also adopts a double-back design, but it belongs to the "sacral support", which can improve some of the low back pain caused by sacroiliac disorder and lumbar spine disorder. And there is no restriction on the crowd, fat and thin can be used, regardless of health or not. The mechanical support design is better than the lumbar support, and the comfort is higher. However, the up and down of the back of the chair is not seamless, and there is still a little "compensation" in the lumbar spine.
, lumbosacral support
It's one of the best ways to support it at the momentLumbar supportwith, sacral supportWhen the advantages are combined, the sacrum, lumbar spine, and thoracic spine will be held up, and the support strength can be automatically adapted, and the comfort is very nice. Such as Okamla in Japansylphy light, it's outstanding.
Fourthsylphy lightGet hands-on
Okamla is a world-renowned brand of ergonomic chairs with unique design and high comfort, which is deeply loved by consumers. among otherssylphy lightSpecially designed for Asians, it is suitable for both business and home leisure. Eight words to summarize:Start with your looks and stay true to your comfort
sylphy lightIt's comfortable because it has a unique lumbar support system. Foreign high-end brands are all this kind of single-back chairs, with integrated lumbar and back support, seamless connection. For example, the 10,000-yuan HM adopts this design, which can fit perfectly with the S-curve of the spine. However, the requirements for design and development capabilities are very high, and there are very few seats in China.
The Sylphy Light backrest is made of one-piece, low-stretch mesh, which has the advantage of a very good fit on the backrest. The back of the chair is evenly stressed, without the frustration of the double-backed chair, and the excessive support of the thoracic-lumbar spine is very natural. Whether it is a standard body or a petite body, there will be a very good sense of experience.
Some people may ask, since it is a mesh cloth that has been used for a long time, will it lose its elastic support?
sylphy lightThe imported high-quality shell hole mesh cloth is used, and the special weaving method has low toughness, and it will not change its shape after repeated pulling, and it is also comfortable and breathable, so it can be used with confidence.
Sylphy Light not only has conventional lumbar support, but also thoracic spine support, sacral support below, and dynamic support for the whole spine, which is the biggest difference from domestic chairs.
Ordinary ergonomic chairs, when you are sitting, the upper body gravity is pressed on the lumbar spine;sylphy lightThe pressure is evenly distributed to the thoracic spine, lumbar spine, and sacrum. For example: it turns out that the lumbar spine is doing the work alone, and it is so tired that it is necessary to live;Now the thoracic spine, lumbar spine, and sacrum are shared by three people, and everyone is very relaxed, and this issylphy lightThe reason for the comfort of the lower back support.
Manually toggle the slider to adjust the support of the seat surface to suit different body types. Different heights, different waist circumferences, and the length of the S curve of the back are not the same, butsylphy lightThe back of the chair can be automatically adapted, and the mesh will automatically adjust the horizontal and longitudinal tension to adapt to the S curve of different people.
Comparatively speaking, the S line of the back of many domestic chairs is fixed, and it is comfortable only if the curve of your back coincides with the curve of the backIf the size ratio does not match, the experience is almost meaningless. Although they are both ergonomic chairs, the comfort level is different, and the details show the level of design.
In fact, choosing a chair is choosing a lumbar back support systemsylphy lightIt can be used by normal people, and it is also very helpful for the recovery of lumbar spine disorders and sacroiliac disorders, and relieves the pain caused by them. Let me tell you a secret about the use of tail spine pain caused by prolonged sittingsylphy lightStraighten the sacrum and the improvement will be obvious.
Some people may ask, since it is a mesh cloth that has been used for a long time, will it lose its elastic support?
sylphy lightThe imported high-quality shell hole mesh cloth is used, and the special weaving method has low toughness, and it will not change its shape after repeated pulling, and it is also comfortable and breathable, so it can be used with confidence.
The design of the Sylphy Light seat cushion is also more distinctive, and the curved surface of the seat cushion is higher than the lower edge of the support mesh of the back of the chairLow center of gravity design。When you sit down, the sponge supports your hips and corrects the pelvic positionThe mesh cloth along the lower edge of the back of the chair just corrects the anterior and posterior angles of the pelvis, which makes the waist feel better, and then makes the waist also present the best physiological curve, so that the relevant muscle groups and ligaments can be relaxed.
In terms of the choice of seat surface, I don't recommend the kind of "high-elastic mesh", which has high elasticity and large deformation, and feels good about the hips when you sit on it. Although comfortable, it may not be beneficial for the stability of the sacroiliac bones and should be considered by people who are in good health and have a small body weight. Heavy sitting may also affect the service life, just like the elastic band of clothing, when the elasticity will eventually weaken after repeated stretching, then the comfort will be significantly reduced.
On the contrary, it is more recommended to have a "low-elastic mesh" and a "hard sponge", which are stable from a health point of view and can restrict the sitting posture to a certain extent. As for choosing mesh or sponge, it depends on personal preference, the mesh is breathable, and the sponge should be more comfortable, each with its own advantages.
The foam cushion of different hardness used in Sylphy Light is molded in one step, which has good elasticity, toughness and durability compared with ordinary sponges.
The core things of Sylphy Light have been finished, the back is comfortable, and the experience is good. As for the handrails, five-star feet and other accessories are very good, after all, it is an international brand, you can go to the official website to check it yourself. The counterweight of the whole chair is 27kg, and the stacking material is quite sufficient, and Okamla is still quite good in terms of quality control.
Many foreign high-end brand chairs do not have headrests, but Sylphy Light can be optional, and friends who need to take a lunch break can buy it additionally.
There are also shortcomings of Sylphy Light, although the seat cushion and backrest are very good, but the height compatibility is weak, the best fit is 155-175cm, which may be related to the designer, the Japanese are short, and there is no way. However, it is also flawed, and height compatibility does not prevent it from making it an excellent chair.
5. Summary
Most people are tired from work and have low back pain, so they remember the ergonomic chair. When pain occurs, muscles, ligaments, fascia, lumbar spine, sacroiliac bones, etc. may have problems to varying degrees.
The problem of the waist is to divide and nourish seven, and the role of the ergonomic chair is to "raise", and it is also the "raising" at work. The "nourishment" in free time is to participate in more physical exercises, and the waist, abdomen, and core muscles are trained Xi. As for how much you want to spend on a chair, it depends on your financial situation and your concern for health.
This is some of the ergonomic chairs I have used, two of which are Okamura, each with a price of 3000+, and only after using it can I have a say. The background is the same, this is not processed by online ps.
At present, with my financial ability, I stop at Sylphy Light, I can't afford a chair of 10,000 yuan, and Sylphy Light has met my needs. If your budget allows and your height is compatible, you won't be disappointed if you want to get started with Sylphy Light.
