No matter whether you lower your head or not, watching electronic products in the same position for a long time will damage our cervical spine and lead to chronic strain.
When many people experience neck soreness, swelling, pain and other discomforts, they will habitually turn their necks in an attempt to relieve them through short-term posture changes. However, as everyone knows, these habitual movements may not only fail to relieve the discomfort, but may also aggravate the damage to the neck. The injury may lead to dizziness, headache, nausea and other symptoms, which may lead to stroke or even paralysis in severe cases.
These 4 types of people turn their necks
Be careful of all kinds of hazards coming to your door
The common characteristics of people who lower their heads are working and looking at mobile phones for long periods of time. During this period, the head puts a lot of pressure on the intervertebral discs. Lowering your head for a long time will cause excessive strain on the neck muscles and ligaments. Over time, this condition may lead to low muscle strength and weak ligaments, aggravating the damage to the cervical spine. At this time, if you suddenly turn your neck, it may cause muscle fiber rupture, causing internal bleeding in the muscle. The blood congestion may adhere to the small internal nerves. Later, when you perform larger local activities, it will stimulate the adhered nerves and cause neck pain. Pain, long-term pain will form long-term chronic pain.
The neck is the only way to connect our brain and body, so there are many blood vessels leading to the brain throughout. Patients with high blood pressure often have problems such as arteriosclerosis and thickening of blood vessel plaques. If they suddenly turn their heads at this time, it may first compress the blood vessels in the neck, making them narrow and thin, causing insufficient blood supply to the brain and causing dizziness, Nausea and other symptoms; secondly, it may also cause plaque in the compressed blood vessels to fall off and enter the brain with the blood, increasing the risk of stroke.
As the age increases, the bone function begins to enter the regression stage. The collagen of the annulus fibrosus changes from fibrous type to cartilage type, affecting the integrity of the fibrous annulus and tensile strength , causing intervertebral disc degeneration.
After the intervertebral disc degenerates, its resistance will be weakened. If you suddenly turn, twist or shake your head at this time, it can cause the pressure of the nucleus pulposus to increase unevenly, deepen the rupture of the annulus fibrosus, and cause cervical disc herniation. disease.
Under normal circumstances, the spinal cord is surrounded by cerebrospinal fluid , which protects the spine from injury during movement. The spinal cord belongs to the central nervous system , which controls movement, feeling, breathing, etc., and is one of the prerequisites for our human body to move freely.
Whether it is a sudden external force or one's own movements such as turning and shaking the head, any cause that can compress the cervical spine may reduce the storage space of the spinal cord, causing damage to the spinal cord in the neck. In severe cases, paralysis or even death can occur.
If you want to have a healthy cervical spine, the best way is to stop being a bowhead! When working or studying, you can set an alarm clock, get up and walk around every half an hour or an hour, and move your eyes away from the screen to look into the distance. This can not only protect the cervical spine, but also relieve eye fatigue, lumbar muscle strain, and frozen shoulder. and many other discomforts~
