Don't miss every push

The author: Xiao Chengwei, orthopedic surgeon of Sichuan Provincial People's Hospital

Ushering in the "Mid-Autumn + National Day" holiday, are you always sitting on the sofa to catch up on drama, or hard at work, or lying in bed playing mobile phones, or walking in tourist attractions?

For many people, sitting and standing for long periods of time has become the norm. So long sitting, long standing, long lying or long walking, which is more harmful to the body?

【 Sedentary 】

Lumbar disc herniation + venous thrombosis

"Sitting for a long time can easily cause lumbar disc herniation." Many people will choose to travel to the surrounding cities on vacation, and for people who drive for a long time to sit down, and sit in the wrong position, it is easy to lead to lumbar disc herniation.

Dr. Xiao Chengwei introduced that the "lumbar intervertebral disc" is the connection of the lumbar vertebrae, similar to a soft cushion, which can buffer the strong shock brought by the outside of the body, maintain the height of the spine, and maintain the spinal motion.

In addition to causing a herniated lumbar disc, sitting for long periods of time can also lead to blood clots in the lower limb veins. Sitting for a long time, the human blood circulation will be affected, the speed of blood flow is slower, and the lower extremity is more prone to venous thrombosis.

When a blood clot forms in a vein in the foot, the clot blocks the blood vessel and causes the return of blood to be blocked, causing the blood to clot. When the thrombus spreads all the way to the iliac vein and inferior vena cava with relatively large diameter, due to the large blood vessels, part of the blood flow will wash away the thrombus and cause large thrombus to fall off. Once the large thrombus falls off, it will cause massive pulmonary embolism and the fatality rate is very high.

Dr. Xiao Chengwei reminded that if you have to sit soon because of work and study, it is recommended to put a cushion on the waist while maintaining a good sitting posture. If you can, you can sit for 40 minutes and then stand up and move.

【 Long station 】

Lower limb varicose veins

Most people are off for the holiday, but some people stick to their jobs, such as waiters, shopping mall salespeople, doctors and nurses. People in these occupations often stand for a long time, often for hours at a time.

Dr. Xiao Chengwei reminds that standing for a long time can easily lead to varicose veins in the lower extremities!

The most common appearance of varicose veins in life is that the blood vessels in the lower extremities are like "earthworms". The harm of varicose veins is mainly due to high venous pressure, which will eventually cause patients to appear - acid distension, weakness, swelling pain of lower limbs; Skin color changes, rashes; Skin ulcers, difficult to heal...

Over time, the symptoms gradually worsen, which in turn seriously affects the quality of life of patients. Dr. Xiao Chengwei said that in terms of life and work habits, if you want to prevent varicose veins, you should first try to avoid standing for a long time and sitting for a long time.

Secondly, calf muscle contraction can effectively help lower limb venous return. Therefore, proper exercise is beneficial to promote venous return. If prolonged standing or sedentary time is unavoidable, medical intravenous elastic socks (primary pressure) can be worn to prevent it.

【 Long lying 】

Cervical dislocation

After talking about sitting and standing for a long time, when it comes to lying down, Dr. Xiao said that compared with the first two, lying down may be relatively better, because lying down is less harmful to the spine, and it is not easy to cause lumbar disc herniation.

"However, lying for a long time without a pillow can cause damage to the cervical spine." Dr. Xiao added that many people will feel sore neck after lying down for a long time, and how to make it uncomfortable. The root cause of these problems is closely related to cervical joint dislocation.

Health chart

For a long time with the wrong posture has been lying, it is very likely to appear cervical spondylosis. If it is because the pillow height is not right and the sleeping position is not good, the possibility of cervical spine problems is greater.

Dr. Xiao Chengwei reminds that if you want to lie for a long time, it is best to choose the right pillow, and the height of the pillow should be consistent with the curvature of the cervical spine.

【 Long walk 】

Injury to knee joint, meniscus

Many people travel and walk for a long time during the holiday, and the leg muscles need to metabolize and produce energy, while excessive exercise will make the leg muscles become anaerobic metabolism, resulting in muscle lactic acid accumulation.

Too much lactic acid can make leg muscles sore and difficult to walk. It's a little penny wise and pound foolish to use a day of walking for the next few days. In addition, a long period of violent walking will also lead to leg muscle strength imbalance, it is easy to lead to wrestling injuries.

Dr. Xiao warned that walking for a long time can also damage the human knee joint and meniscus. Complications such as mobility disorder of knee joint, joint effusion and osteoarthritis may occur.
