The core of correct posture is actually three words: don't, low, head. The first trick: Altman style. The main point of action is to relax the neck, hold the mobile phone with your right hand flush with your eyes, and support your right hand with your left hand, so that you can hold the mobile phone conveniently and comfortably. The second measure: reading style. Action points: put your elbows on the table, relax your neck, and raise your mobile phone to almost eye level with both hands.
Another point is to use props, such as mobile phone stands. The bracket should be adjusted to the height of the eyes. Be careful not to bow your head. When a person does not bow his head, his neck only needs to bear the pressure of his head (about 4 ~ 5 kg), which is relatively easy. When a person lowers his head 15 degrees, it is equivalent to the weight on his head 12 kg! A person lowers his head 30 degrees, and his head weight is close to 18 kg! When a person lowers his head 45 degrees, the weight of his head is close to 22 kilograms!
In fact, our necks, like bananas, have a slightly forward-leaning physiological curvature. But always looking down at the mobile phone will make our cervical spine straight and lose the beauty of curve, which will make the muscles in front and back of the neck bend and stretch excessively. At that time, neck pain, shoulder pain, arm pain … all kinds of painful diseases will happen. Please remember the correct posture when using your mobile phone. The core of correct posture is three words: no, low, head!
