Crossing one's legs is a bad habit. What are the serious consequences of crossing one's legs?

I know the serious consequences of crossing your legs:

1. Aggravating varicose veins and making your legs and feet prone to numbness

Crossing your legs can easily block the blood flow of the femoral artery , affecting the normal circulation of blood in the lower limbs, easily causing numbness in the legs and feet, and even pain in severe cases.

2. Injury to the spine and prone to low back pain

When people cross their legs, it is easy to bend and push the back. If things go on like this, the human spine will deform, resulting in uneven pressure distribution between the lumbar and thoracic vertebrae, and the waist Muscle soreness, severe cases may cause lumbar disc herniation and induce ankylosing spondylitis.

3. The pelvis is tilted high and low, which is easy to form high and low shoulders

Crossing the legs for a long time will cause the position of the femoral head in the acetabulum to change, which will affect the stability of the hip joint in the long run. The position of the joints is one high and the other low, resulting in a serious tilt of the pelvis. The tilt of the pelvis also causes uneven stress on the shoulders, which can easily lead to uneven shoulders over time.

4. Damage to male reproductive health

This worry comes from the fact that the thighs are more likely to close tightly when the legs are crossed, and the scrotal temperature increases, thereby damaging sperm development. In response to people's concerns, scientists found that the temperature of the scrotum increased by 1.4°C and 2.7°C when wearing clothes and crossing the legs compared with the temperature under the naked legs. However, on the one hand, in daily life, people do not remain naked with legs apart 24 hours a day. What's more, there is a lack of evidence whether this increase in temperature can increase the risk of male infertility. Affects male reproductive health. When the legs are crossed, the legs are usually closed tightly. The skin on both sides of the thighs is in close contact with the reproductive organs, and the temperature rises. The temperature exceeds the optimal temperature of sperm by 35 degrees, which affects the survival of sperm.

5. Splayed feet and piriformis muscle injury

For people who often cross one leg, you will find that when they cross the leg on one side, the foot will easily move outward when walking, similar to For people with unilateral splayed feet, these people are also prone to piriformis syndrome, because the piriformis is an external rotator muscle, and long-term shortening may cause pain points, stimulate sciatica, and induce pain!

6. Common peroneal nerve entrapment syndrome

Common peroneal nerve entrapment syndrome is mainly seen in tibial plateau, fibular head and neck fractures, as well as acute or long-term chronic excessive knee joint Compression of the common peroneal nerve by flexing the peroneus longus muscle. Although half-flexing the knee joint of cross-legged legs may stretch the common peroneal nerve, and may cause numbness if the time is longer. Presumably it is this numbness that leads people to believe that nerve damage has occurred. In fact, feelings such as pain and numbness are the body's protective mechanism, indicating that injury is beginning to occur and should be avoided in time. The numbness that may be caused by crossing your legs serves as a warning to avoid real injury.

7. Promoting diabetic foot disease

One of the most common complications among people with long-term diabetes is vascular disease, which itself can affect blood flow, causing one limb to weaken another limb. The pressure can aggravate the poor blood flow and induce or aggravate the occurrence of diabetic foot disease. People with diabetes should avoid stretching their legs!
