May cause big problems, the sleeping posture of well-known male actors in the drama is causing heated discussions! Sleeping like this is equivalent to hanging 16 bottles of mineral water around the neck, Yang Yang | neck | sleeping posture

Recently, the TV series "You Are My Human Fireworks" starring renowned actor Yang Yang is currently airing, and multiple scenes from the show have made headlines and sparked heated discussions. Among them, Yang Yang's serious sleeping posture in the drama has also sparked discussion.

Originally, compared to the sleeping posture of ordinary people

Yang Yang slept very seriously

His head, neck, and shoulders were stretched in a straight line!

After the broadcast of this scene, it sparked a heated discussion among netizens:

Sleeping like this makes my neck feel tired

So, how much pressure will Yang Yang's cervical spine bear? Some netizens calculated based on the principle of leverage, which means that the weight torque of the head is equal to the traction torque of the neck muscle group.

The weight of an adult's head is approximately 5kg, and the force arm of the head gravity in the picture is approximately 2/5 of the head length, which is about 8.8 centimeters. The force arm of neck traction can be calculated by length and angle.

According to the formula, how much force did Yang Yang's neck bear? You can pick up the pen and do the math. As a result, Yang Yang's neck was subjected to a force of about 80N in this sleeping position, equivalent to a weight of 16 pounds, and he hung 16 bottles of mineral water around his neck!

Improper sleeping posture can lead to systemic diseases

"The cervical spine is the most 'precious' part of the human body, supporting the head and the trunk, playing a role of' connecting the upper and lower parts'. Therefore, once there is a problem with the cervical spine, if not taken seriously, it may affect other parts." Wu Lianguo, director of the Orthopedics and Traumatology Department of the Second Hospital of Zhejiang University of Traditional Chinese Medicine, said that improper sleeping posture can induce diseases such as cervical spondylosis, hypertension, arrhythmia, and stomach diseases.

"Sleeping in a position like that of actor Yang Yang in the drama, with an 'empty neck and tense muscles', can easily trigger cervical spondylosis." Wu Lianguo said that this sleeping position is equivalent to only sleeping in half of a pillow, which can keep the neck suspended and stiff, and the cervical spine cannot be supported, which is not conducive to maintaining normal physiological curvature.

Some sleeping positions are signals sent by diseases

"Some sleeping positions may indicate that there is a problem with the cervical spine," Wu Lianguo said. For example, in the "surrender position", the hand is raised above the head. This is because the soft tissues in the neck and shoulders are too tight, and raising the hand can alleviate muscle tension and slow blood circulation, which can cause difficulty falling asleep.

"Some people wake up in the morning with their head not on the pillow, repeatedly falling on the pillow, feeling more comfortable sleeping on their stomach, getting tired as they sleep, or waking up with a tight neck, preferring to use a high pillow, all of which are caused by sustained tension and spasms in the neck muscles, or sprains, deformations, or lesions." Wu Lianguo said.

From the perspective of cervical health, the correct sleeping posture requires maintaining the normal physiological curvature of the cervical spine while ensuring natural relaxation of soft tissues such as muscles and ligaments throughout the body. The best sleeping position is supine, which can best maintain the natural curvature of the cervical spine.

"When lying on the back, a cushion can be placed at the neck, waist, and knee joint popliteal fossa to better support the curvature and relax the muscles." Wu Lianguo said that people who are accustomed to sleeping in a lateral position can clip a blanket or pillow between their legs. The pillow should be at the same height as their shoulder, and they need to sleep on both sides to avoid sleeping on one side for a long time, otherwise it is easy to have scoliosis.

Protecting cervical health, in addition to proper sleeping posture

Choosing the right pillow is also important

"Generally speaking, a pillow height of 10-15 centimeters is more suitable, and the specific size depends on each person's physiological curvature. The general principle is that after sleeping, the part of the pillow that supports the curvature of the cervical spine is 3-5 centimeters higher than the part that supports the back of the head, which can support the head and adapt to the height of the neck." explained Dr. An Zhongzhong from the Orthopedics and Traumatology Department.

"From the perspective of pillow material, some traditional fillers commonly found in pillows, such as buckwheat husks, cassia seeds, bran, and other natural plant-based materials, can be selected. It is not easy to collapse, can not only support our cervical curvature well, but also maintain freshness and breathability, ensuring smooth blood flow and relaxing tense muscles." An Zhongli believes that common "memory pillows" and tall latex pillows are also good choices.

According to relevant research literature, pillows are arranged in descending order of comfort: latex pillows, traditional pillows such as buckwheat leather, polyurethane memory pillows, and down pillows.
