[Countless Heroes Bow Down] Reminds us that waist is [fragile]. If you use it carelessly, heroes cannot carry it.
Yes, the waist will be used in any daily movement, so if we are not careful, we will [flash].
Today, Dr. Clove will work with you to find out the bad habit of hurting the waist.
Incorrect sitting posture
This is the most common cause of lumbago.
The wrong posture will cause the lumbar spine and muscles to be excessively pulled and squeezed, making them uncomfortable for a long time, and finally you are the one who is uncomfortable.
Single hand weight
Although we carry heavy objects by hand, our waist also bears a large part of the weight.
If you think about it, one side of the waist will be more tired and easier to be “flashed” if it is light and heavy, and the stress is uneven for a long time.
Bend over without bending one’s legs
When people lift heavy objects, they bend down directly to pick them up. The pressure on the waist is very great.
Assuming that the pressure on the lumbar spine is 100 when standing, the pressure will increase to 220 when bending down, which is more than twice.
Therefore, no matter whether it is to carry heavy objects or pick up a piece of paper on the ground, don’t bend down directly.
Stand for a long time
Now many people know [sitting for a long time hurts the waist], so they all choose to work standing up.
As we said earlier, the pressure on the lumbar spine when standing will be less than that when bending over or sitting, but the waist will be tired when standing too long.
