In retrospect, it wasn't unrelated to the fact that I used to watch TV when I was a child. So Xiao Bian went deep into the study and lay down to watch TV and read books.
Hazard I: blurred vision, decreased visual acuity
When watching TV, the eyes cannot be kept on the same horizontal line as the TV screen. This requires adjustment with the eyes. It causes the eyes and lateral rectus muscles and the upper and lower oblique muscles to wear out and contract and cause strabismus. disease. Not only does it make you feel tired easily, but it also easily causes diseases such as eye astigmatism. A long time will cause the external eye muscles and ciliary muscle contraction in the eyeball, resulting in eyeball swelling, conjunctival hyperemia, binocular tears, and even increased intraocular pressure, blurred vision and decreased visual acuity.
Hazard 2: insomnia, neurasthenia
As most of the body's muscles have relaxed, the body's breathing and blood circulation slow down, the brain's central nervous system gradually enters a suppressed state, and the brain's thinking and memory abilities are greatly reduced, resulting in serious disorders of depression and excitement. Not to appreciate the purpose of television programs, but also can cause insomnia, neurasthenia and back pain and other adverse consequences.
Hazard 3: Induced cervical spondylosis or even joint dislocation
Many people like to watch TV in bed on a rest day. As a person maintains a posture for a long time, the body activity of the person is relatively low. At this time, the head maintains a posture for a long time, and the neck muscles are prone to fatigue and stiffness. In this case, when the head rotates, the muscle response ability will be weakened, resulting in joint dislocation, muscle sprains, induced cervical spondylosis, and even serious joint dislocation.
Not only that, bad posture can also cause the normal curvature of the cervical spine to disappear or even bend in the opposite direction, which can cause instability of the spinal column due to cervical spine intervertebral ligament injury. In addition, in order to maintain such a posture for a long time, some muscles and tendons are always in a state of tension in order to maintain the balance of the body's center of gravity, resulting in ischemia and hypoxia, and this causes a long-term fatigue state such as stiffness of the entire back muscle.
Are the buddies scared? Xiao Bian himself can not help but adjust the sitting position. Here, we still advise everyone not to cope with a moment of comfort and lie down or watch TV in some weird posture. The correct posture should be to take a seated position and watch the proper time to move about the neck. Of course, more exercise and more fitness are the best ways to stay healthy.
