First of all, the so-called supine position, similar to frog position, is used in our clinical imaging examination of hip joint ("big hip" film). Frog position is to let the patient lie on his back, bend his knees 45 degrees and stick it as straight as possible on the bed. The whole posture is like a frog facing the sky, so it is called frog position.
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.
The posture of "lying in the sun" is a health-keeping action of Chinese medicine. The images on the internet are all fantastic, so let's put them aside first. First of all, it is clear that it is not suitable for sleeping.
Sleeping posture is very important for health.
Lying flat posture:? Lying flat is one of the most respected sleeping positions, which can make the body in a state of natural relaxation and reduce the pressure on the cervical spine and spine.
Lying on your side: Lying on your side is also a good choice, and the joint pressure 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.
Sleeping posture:? Sleeping prone position is a kind of sleeping position that easily leads to compression of cervical and lumbar vertebrae, and it is not recommended.
Curling posture: This sleeping posture is equivalent to bending down for a long time, which easily leads to the straightening of cervical and lumbar vertebrae. 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.
