Bad posture will bring hidden dangers to health.
Prolonging the neck for a long time will make the neck muscles tense for a long time, lead to muscle injury, increase the burden on the cervical spine, cause numbness and pain in the upper limbs by compressing the nerves in the spine, and may also lead to dizziness, headache and cervical spondylosis. Studies have proved that the weight of the head will double every 5 cm forward. The driver's back should be near the seat.
Low-headed people easily lead to the physiological curvature deformation of cervical vertebra, and then get cervical spondylosis. According to statistics, people bow their heads more than 1000 times a day, and the time can reach 7-8 hours.
Sleeping on your stomach can lead to dizziness, headache and even nerve damage. You'd better sleep on your stomach with a nap pillow. If you don't have a nap pillow, you can use a cushion.
Standing sideways will cause the spine to bend, with one shoulder high and one shoulder low. Standing sideways for a long time will affect posture, and the body will cause scoliosis. Severe scoliosis can lead to poor breathing. Mild scoliosis can be corrected by exercise, and severe scoliosis requires surgery.
