● hazard 2: insomnia and neurasthenia
As most of the muscles of the body have been relaxed, the breathing and blood circulation in the human body have been slowed down, the central nervous system of the brain has gradually entered a state of inhibition, and the thinking and memory ability of the brain has been greatly weakened, resulting in a serious disorder of inhibition and excitation, which not only fails to achieve the purpose of enjoying TV programs, but also causes insomnia, neurasthenia, backache and other adverse effects Fruit.

Many people like to watch TV in bed on a rest day. Because they keep a posture for a long time, their body activities are relatively less. At this time, when the head keeps a posture for a long time, the neck muscles are prone to fatigue and rigidity.

Not only that, the bad posture will make the normal physiological curvature of the cervical spine disappear or even bend to the opposite direction, which will lead to the instability of this section of spine due to the injury of cervical spinal ligament. In addition, to maintain such a posture for a long time, some muscles and tendons in order to maintain the balance of the human body's center of gravity will always be in a state of tension, leading to local ischemia and hypoxia. For a long time, this will lead to the whole neck back muscle's stiff spasm and other fatigue state.
