Recently, "You Are My Human Fireworks" is on the air, and many bridges in the play have appeared on the hot search to cause heated discussions. For example, the sleeping posture of the male protagonist in the play "one book is serious" has also triggered discussion.
Compared with the sleeping posture of ordinary people, the male protagonist slept very "seriously", and his head, neck and shoulders were stretched into a straight line!
After this shot was broadcast, it caused heated discussions among netizens: I feel very tired from sleeping like this...
01 Sleep like this
This is equivalent to 16 bottles of mineral water hanging around your neck
Talented netizens calculated according to the principle of leverage.
The weight of an adult's head is about 5kg, and the force arm of the head gravity in the picture is about 2/5 of the head length, about 8.8 cm. The force arm of neck traction can be calculated by length and angle.
According to the formula, how much force does the male protagonist's neck bear?
As a result, in this sleeping position, his neck bears a force of about 80N, which is equivalent to carrying 16 pounds, and hangs 16 bottles of mineral water on his neck!
Wu Lianguo, director of the Second Department of Orthopedics and Injuries of the Second Hospital of Zhejiang University of Traditional Chinese Medicine (Provincial Xinhua Hospital), said that improper sleeping posture can induce diseases such as cervical spondylosis, high blood pressure, arrhythmia, stomach disease and so on.
"Like the sleeping posture of the actor in the play, 'the neck is empty, the muscles are tense', which can easily induce cervical spondylosis." Wu Lianguo said that this sleeping position is equivalent to only half sleeping on the pillow, which will keep the neck suspended and stiff, and the cervical spine cannot be supported, which is not conducive to maintaining normal physiological curvature.
02 What other sleeping positions are there?
There are also pits
·
Eight feet outside
When our feet fully do the outer eight movements, the waist will arch up, and the thigh bone will rotate outward, which will cause back pain in the long term.
·
Excessive curling
When we curl up too much to sleep, the back will be in a state of arching, and the muscles of the back will be overstretched and relaxed.
This is not good for our thoracic, lumbar, cervical, and even entire spine.
·
Sleep on your tummy
Sleeping on your tummy is indeed comfortable, but don't neglect your health by being comfortable.
When sleeping on our stomachs, our head will turn sideways, which will put our cervical and upper thoracic vertebrae in a twisted state, which is unhealthy for our spine.
In addition, when we sleep on our stomachs, breathing problems will also occur, including a certain squeeze of the heart and lungs, affecting cardiopulmonary function.
03 What is the "gold medal sleeping position"
For the vast majority of people without physical ailments, lying on the right side and lying on their back (feet naturally separated from shoulder width) are suitable for the vast majority of people.
If you want to better protect your spine or have lower back or leg discomfort, you can also have some small tips.
·
Lie on the right side
When lying on the right side, we must pay attention to the height of the pillow, the pillow should be shoulder height, we can't tilt our head, put the head in a neutral position, so that the muscles of the entire neck and shoulders are more relaxed and less labor.
It is also possible to clip a thin cushion between the two knees, which will keep our pelvis in a neutral position and avoid excessive twisting due to crossed legs when we are asleep.
And you need to sleep on both sides to avoid sleeping on one side for a long time, otherwise scoliosis is prone to occur.
·
Supine
When lying flat, you can also pad a cushion in the neck, waist, and popliteal socket of the knee joint, which can better support the curvature and make our muscles more relaxed.
