Female body sculpting has no intention of hurting the waist 4 major original sins
Studies have shown that when the human body sits 20 degrees forward, the pressure in the lumbar intervertebral disc is the largest.
This is exactly what we often do when we do reports in the computer, go online, and play online games.
Sitting for a long time, the lumbar vertebrae are pressed down and the whole body is shortened, and the middle tilt of the body is followed by the rearward movement, so that the intervertebral disc protrudes backward.
銆€銆€Tiredness: 25 hours a day, excessive flexion of the lumbar spine In our daily activities, the lumbar spine is mostly in a flexed state, and excessive work is equivalent to increasing the time of lumbar flexion.
Statistics show that the frequency of lumbar flexion can reach 3000-5000 times a day.
This excessive, repeated flexion is the most common cause of disc complications.
銆€銆€Vibration: The lumbar vertebrae were tested while driving, and the spine was repeatedly stretched. Scientists found that the natural frequency of the lumbosacral region is in the same range as the vibration of the chair in the driving, so the lumbar vertebrae easily resonate with the car when driving.
This resonance means that the spine is continuously compressed and stretched, and the surrounding tissue muscles are also fatigued, affecting the metabolic rate of the lumbar intervertebral disc, which accelerates the degeneration and deformation of the lumbar spine.
銆€銆€Cold: revealing a small waist, affecting the nutritional supply of the lumbar spine, especially the cold.
If the waist is exposed in winter, in order to resist the cold, the muscles in the lower back contract and the small blood vessels contract, resulting in a decrease in local blood circulation, which will affect the nutritional supply of the intervertebral disc, and the pressure in the intervertebral disc will increase, causing more damage.
銆€銆€Meng: Suffering from external forces, prone to lumbar sprains, normal lumbar intervertebral relationship is flexible and powerful, has a strong ability to withstand pressure, can withstand 450 kg of pressure without any injury.
But these forces must be gently pressed from the front. If you suddenly feel stressed or suddenly exerted strength after lack of exercise, it is easy to break through its limits and cause a sprained waist.
