People who often bow their heads and hunch their backs often grow a fist-sized bag on the back of their necks.
This not only affects the curvy beauty of the neck, but also makes the head appear large and the neck is thick.
This bag is what we often call the "rich bag".
Today, "Ask the Doctor" will tell you in detail about how it works and how to eliminate it.

The rich bag is actually a lumbar and cervical vertebrae, a lump that is misaligned at the junction and bulges.
Normally, our cervical spine is slightly forward-leaning and can rotate flexibly. The thoracic spine, on the other hand, is convex and basically remains motionless.
If our cervical spine is too forward or the thoracic spine is excessively concave, the junction of the two will be misaligned, and the muscles attached to it will spasm and swell.
And because this position is more fragile, the body will send more fat to accumulate here, which has a fixed effect.
As a result, the richer the bag also grows bigger and bigger.
(1) People with the cervical spine leaning forward
Round shoulders, chest, and hunchback can all cause the cervical spine to lean forward for a long time.
This will correspondingly cause the thoracic spine to lean back, causing the junction to bulge and grow a rich bag.
How do I know if the cervical spine is leaning forward?
Stand relaxed, feet together, and let the people around you observe whether your earlobes are on the same vertical line as your shoulders.
If the position of the earlobe is in front of the shoulder, it can be judged that the cervical spine is leaning forward.
(2) People whose pelvis tilt forward causes the lumbar spine to lean back and the cervical spine to lean forward
When the pelvis leans forward, the center of gravity of the body moves forward. To maintain balance, the thoracic spine gradually moves backwards.
At the same time, in order to avoid the body falling backwards, the cervical spine will gradually lean forward.
Misplaced cervical and lumbar vertebrae will appear at the junction of the rich bag.
The typical feature of pelvic forward tilt is a kyphosis of the buttocks, while the lumbar spine and lower abdomen are convex. Moreover, it is easy to have waist pain after standing for a long time.
How do I know if my pelvis is leaning forward?
Stand against the wall, with the back of your head, shoulders, and hips pressed against the wall.
Insert one hand into your waist:
If you can only insert one palm in the lumbar gap, that's a normal posture.
But if you can insert a fist, or even have excess, it's the pelvic leaning forward.
Rich bags do not grow out in a day, and it is not an overnight thing to eliminate it, mainly by insisting on correcting bad posture.
Action 1: Adjust the cervical spine
Stand against the wall, make sure that the heels, hips, back, and back of the head are pressed against the wall, and the arms are opened and lifted.
In the process of continuous lifting, make sure that the arms and the back of the hand slide against the wall as much as possible.
This action can relax the chest muscles while strengthening the back muscles, which can be said to kill two birds with one stone.
Action 2: Adjust the pelvis and spine
Training Goal: Relax the muscles that will tilt the pelvis forward and increase the strength of the muscles on the posterior side of the pelvis.
Movement: Support on one knee, keep the upper limb stable, the same side hand grasps the same side of the foot, while stretching the calf in the direction of the thigh, slowly tilting the body forward, by stretching the inner thigh muscles, pulling the pelvis in the same way, so that it returns to the correct position. Alternating 8 to 10 times between the left and right legs.
Action 3: Contract your chin
On the basis of adjusting the spine and lumbar spine, insisting on practicing chin contraction can help us quickly eliminate the rich bag.
Movements: The cervical spine remains perpendicular to the ground, then the chin is slightly retracted and the cervical spine moves horizontally backwards.
