"Sunward Lie" requires the body to lie flat naturally, with both hip joints relaxed, feet close together, both legs extended to both sides, as far as possible attached to the bed, with correct breathing methods, to help the body absorb more oxygen and restore health. It is an important exercise method in TCM health preservation. Some netizens said that it is very comfortable to complete this action. Some netizens said that they felt "paralyzed" in their lower limbs after finishing this action, while others complained that they could not finish this action. From the beginning, they found the "big hip" (hip joint) unbearable. Why? This posture is similar to the action-frog posture ("big hip" photography) we use in clinical hip imaging examination. The so-called frog position is to let the patient lie on his back, bend his knees 45 degrees, and stick them straight on the bed as far as possible. The whole posture is like a frog on his back, so it is called frog position. It is often used for the examination and diagnosis of congenital dislocation of hip joint in children. When you want to know whether there are lesions in the upper and lateral positions of femoral head, bilateral acetabulum and bilateral femoral neck, you need to take frog radiographs of bilateral hip joints.
Our hip joint, which is composed of femoral head and acetabulum, belongs to ball-and-socket joint and is a typical pestle-acetabular joint. The normal range of motion of hip joint is: flexion (leg forward): the normal range is 0-135; Backward extension (leg extension): the normal range is 0-20; Abduction (leg lift to the outside): the normal range is 0-60; Adduction (inward leg clamping): normal range 0-40; Internal rotation (toe turning to the other foot): the normal range is 0-45; External rotation (toe turning with the other foot behind): The normal range is 0-45.

When the "big hip" is sick, that is, when there are diseases such as femoral head necrosis, hip impact syndrome and dislocation of hip joint, the range of motion of hip joint in all directions decreases; At this point, the patient can't complete the action of "lying in the sun", or there is pain or even fear when doing this action. Lying in the sun, the hip joint will be in a state of flexion, abduction and external rotation, that is, the "big hip" will be in a state of "nesting". There is no problem for a short time, but if you stay in this state for a long time, if you fall asleep in this position, you will not relax, but will cause cartilage or glenoid lip damage because of the increase of pressure between the femoral head and acetabulum, and the nerves and blood vessels around the hip joint will be in a state of flexion and traction, which will cause nerve paralysis, blood circulation obstruction of lower limbs and other diseases. That is to say, lying in the sun for a long time will hurt your hips, so don't sleep in this position.
Sleeping posture is very important for joint health. 1. Lying flat posture: Lying flat is one of the most respected sleeping postures, which can make the body in a state of natural relaxation and reduce the pressure on the cervical spine and spine. 2. lateral position: lateral position is also a good choice, and the pressure on the joints is relatively small. In addition, you can choose to bend your legs up a little (pad the posterior cranial fossa of your knees), which can reduce the pressure on your knees and hip joints. 3. Sleeping posture: Sleeping posture is a kind of sleeping posture that is easy to cause compression of cervical vertebrae and lumbar vertebrae, and it is not recommended. Generally speaking, lying flat and lying on your side are the most beneficial sleeping positions for joints, but everyone's situation is different. Choosing a sleeping position that suits you also needs to proceed from specific situations, such as whether there are problems such as cervical vertebrae and lumbar vertebrae, and whether there are obstacles in breathing. Whether you are lying on your side or lying on your side, it is unhealthy to keep a posture for a long time. It is difficult for most people to master their sleeping posture after falling asleep, so they usually change their posture. Therefore, it is particularly critical to choose a mattress with moderate hardness and a pillow with moderate height, and to maintain a correct and healthy posture before going to sleep, because these factors are controllable. Correctly understanding or trying to use "pattern nest" may bring benefits to some people, but over-interpretation or misuse will be counterproductive.
