Laptop brings us convenience while also posing a potential threat to people's health. From the perspective of ergonomics, there are some insurmountable defects in the design of laptops. If the distance between the screen and the keyboard is too close, people have to stretch their necks and bow their heads to the screen, resulting in neck muscle damage for a long time. If we raise a laptop to a proper position, people often have to raise their arm when they press the keyboard, which may cause shoulder and arm muscle strain. Many people suffer from cervical spine and waist muscle injury due to sitting posture problems.

Research shows that when people normally raise their heads, the neck can perfectly support the weight of a person's head. Each 1 inch (equivalent to 2.54 cm) of the head goes forward, and the neck must support one more head. When people use laptops, due to their own design defects, they often have to lean their Heads forward. As a result, the long-term weight-bearing neck muscles are naturally not overwhelmed and end up with labor loss, this results in vertebral compression and deformation, and ultimately compress the nerves in the vertebral body to induce cervical spondylosis.

Although there are five different types of cervical spondylosis, at present, more than 76% of office workers with cervical spondylosis aged 30 to 40 years old are caused by labor loss.Cervical Spondylosis. This type of cervical spondylosis is mainly caused by posture fatigue, fatigue, so that the neck soft tissue injury, qi and blood stagnation.

■ Top1: Why do people who often bow their heads to the desk suffer from Cervical Spondylosis

Due to the physiological needs of the human body, each section of the normal spine has a certain curvature, which is called physiological curvature. The Physiological curvature of the cervical spine can increase the elasticity of the cervical spine, reduce and buffer the fluctuation of gravity, and prevent spinal and brain injury.

Often bow his head to the desk, it will make the cervical spine normal physiological flexion straighten, cause many other changes of the cervical spine (such as loosening, hyperplasia, muscle tension, etc.), and thus stimulate peripheral nerves or blood vessels, cause Cervical Spondylosis pain.

■ Top3: how to recover the cervical spine during sleep?

Each person spends 1/3 of his or her time in his or her sleep. A closely-suited pillow for the cervical curvature allows you to work, study, and live for one day, relieve cervical muscle and ligament fatigue during sleep.

According to ergonomics, the shape of the pillow, with the middle of the low, the two sides of the high ingot shaped pillow is the most suitable for cervical physiological curvature. This type of pillow can maintain the physiological curvature of the cervical spine using the protruding area in front. In terms of cushion filler, the slow rebound temperature polyurethane has unique viscosity elasticity and temperature sensitivity. It can be trapped according to the temperature and pressure, but will not rebound. These two features make it a good relief material.

Scientific Choice of pillows to prevent cervical spondylosis, should choose a height not more than 10 cm (shoulder), moderate soft and soft pillows.

Do it yourselfSewed soy bean pillow.The hardness and air permeability of the pillow core filler of cervical spondylosis patients should be moderate. The pillow is good, and the scalp and cervical spine will feel uncomfortable. the pillow is too soft to maintain a certain height. It will make the neck muscle fatigue and aggravate the illness. Some patients made of soy bean pillows have achieved good results. This is because the toughness of soy bean is similar to the hardness of human bones, and it can support the physiological curvature of cervical spine, the Scroll of soy bean will also be used to massage the neck facet disorder and ligament muscle spasm. The specific practice is: Put 2 kilograms of soy beans into a cotton cloth bag with a length of 1 foot (1 foot = 0.3333 meters) and a half foot width to make a pillow with a height of about 10 cm, the height of the gap between the neck and bed is exactly the same as when people lie down, which can make the head, neck, and shoulder feel comfortable.

■ Top4: How does a laptop hurt your cervical spine?

The laptop has serious engineering defects. The screen is too close to the keyboard, and the neck is stiff and the screen is looked down, which may cause cervical muscle damage. The machine is carried to the right position of the eyes, it may also cause shoulder and arm muscle strain. At present, a variety of related lesions have gradually appeared in early notebook users.

The simplest and most effective way for desk workers to prevent cervical spondylosis is to work for about half an hour, lift your head and gently move your neck around. Do not continue your work for more than two hours.

The correct precaution is to use a laptop and an external traditional keyboard. After using books to pad the computer, when the eyes are facing forward, the cervical spine is the smallest pressure. Office workers working with laptops should pad a few books under their computers to raise their monitors and reduce the probability of cervical spondylosis. Book thickness, as long as you sit straight, the line of sight is basically flat with the upper eaves of the display. At the same time, if the external traditional keyboard can reduce the labor loss on the wrist after the notebook is raised, the effect is better.

In addition to using books to pad a notebook computer, choosing a suitable computer support rack to support the computer screen is also a good way to make it parallel to the line of sight. This greatly reduces the lactic acid content in the neck muscles after a long period of work.

■ Top5: prevention and treatment of cervical spondylosis by wall tension?

Sitting on the wall, with the headrest back to the top of the wall, the head and body do not move, but muscle tension contraction, commonly known as "tension ". Or put your hands in the headrest, and put your hands in the forward direction. the headrest goes back, every 3-5 seconds is 1 time. Exercise-times a day, this is a simple and easy way to prevent cervical spondylosis without adverse reactions.
