Better not play with tablet computers!

It's hard to see reading books and newspapers on the subway and bus. Whether white-collar workers or students, they are all immersed in playing with electronic products, posting microblogs, cutting fruits, reading novels... Every day, one thing before and after closing your eyes and the first thing after opening your eyes are using 3c products! The technology and beauty of modern electronic products do fascinate three-year-old children, but too much obsession will lead to a series of potential health problems, from eyes to fingers, cervical vertebra may be involved in disease.

Induced dry eye

When we look at things, the eyelids blink regularly, just like the windshield wiper of a car, which continuously spreads tears evenly on the surface of black and white eyes for lubrication. Normally, the number of eyelid blinks is 10-15 times per minute, but when watching the computer, especially when playing games with high concentration, the number of blinks will be greatly reduced, and the tear film on the eye surface will break over time. Whether for adults or children, long-term focus on tablet computers may stimulate eye congestion, dryness, and induce or exacerbate dry eye symptoms.

It should be noted that winter is the season of dry eye disease. Because the humidity is low in winter, the eyes are easy to dry. If you still stare at electronic products frequently in this season, dry eye disease is likely to recur.

Generally, dry eyes can use artificial tears to alleviate symptoms, but it is important to consciously control the time you use computers and mobile phones, and blink as much as possible.

Cause strain of cervical vertebra

"Tablet computers are very different from ordinary desktops and even laptops. They are really easy to carry, but at the same time, they have no support points, so users often put them on their legs, resulting in excessive neck droop, unnatural body bending, and more and more forward leaning of the neck. This makes the sternocleidomaxillary muscle of the human neck stretch forward continuously, and after a long time, it will be in a chronic hyperemia state, which will easily lead to neck fasciitis, compression of vertebral artery and cervical spondylosis, resulting in chronic strain.

The symptoms of cervical spondylosis are head, neck, shoulder, back and arm pain, stiff neck and neck, and limited activity. For light cases that feel unwell soon after using the tablet computer, as long as they have a proper rest, adjust the length of computer use or change the sitting posture, the symptoms can be alleviated.

The tablet is well placed with a bracket so that the center of the computer screen is at the same level as the user's chest. It can adjust the angle of the display to form an angle where the eyes can gaze at the screen when they are slightly downward, so that the neck muscles can be well relaxed.

In addition, when using the computer, you should have a rest of 5-10 minutes every hour. Move your neck and shake your head to increase the flexibility and muscle strength of your cervical spine and avoid getting stuck in stiffness.

Tendonitis

Whether sitting on the sofa or lying in bed using a tablet computer, this means that most users either place it on their legs or support the computer with their left hand, and use their right hand to continuously gesture and control. Over a long period of time, both hands will be overloaded, and the shoulder and neck will also be overwhelmed, which is easy to cause tendinitis.

This kind of tendinitis is mostly seen in the special occupational groups who need to use their arms excessively, but now it is more and more seen in the ordinary people who are addicted to tablet computers. It seems that the tablet computer is not heavy, but it is very laborious to hold it with one hand when it is in the air. It will cause recessive fatigue to the tendons. At that time, you may feel a tingle, and it will be OK after a short rest. But every day for such a long time, you may find it difficult to raise your hand one day.

In addition, tenosynovitis of the wrist is another major disease that 3c fans may suffer from. It is reported that if you make frequent gestures for a long time, it is easy to make your wrists, forearms and fingers feel tired, which can cause muscle soreness, cramps and weakness. In serious cases, joint degeneration and reduced range of hand movement may even occur.

The health channel of Global Alliance Network reminds you:

Whether you are just having fun or using a tablet under the banner of work, you must be scientific and prudent. The support point is very good. Don't entrust it to your own hands for too long. The rhythm of finger gestures should also be properly slowed down. Otherwise, it would be too uneconomical to hurt your hands and body for electronic products.
