What are the disadvantages of smart phones?

Smart phones are gadgets that we are familiar with now. It can be said that our life is completely inseparable from it. It seems that most people are addicted to using smart phones. Whether eating, taking the bus, going to the toilet or even walking, there are always a large number of people using smart phones. It is harmful to indulge in anything, including smart phones. This time, Bian Xiao will introduce you to eight kinds of harm that smart phones may bring to your health.

1, mobile phone elbow

In fact, mobile phone elbow is also called cubital tunnel syndrome by some people, but it should only be regarded as a kind of cubital tunnel syndrome. Refers to the symptoms of numbness, tingling and pain in forearm and hand caused by compression of ulnar nerve, which spreads through the bone inside elbow. One of the reasons for the compression of ulnar nerve is thought to be the excessive use of smart phones by people. For example, if you put your mobile phone to your ear for a long time, your elbow will bend for a long time. In susceptible people, long-term elbow posture will lead to decreased blood flow, inflammation and nerve compression. Although there is no exact data to show how many people suffer from mobile phone elbow, hand experts say that with the active global 3.3 billion mobile phone service contracts, the incidence of mobile phone elbow is rising.

2, SMS claw

"SMS claw" may not be a formal medical diagnosis, but many people who are proficient in technology do feel the pain of texting, typing or browsing the web. Refers to the pain in the wrist and hands after frequent use. Sometimes this leads to tendinitis, which leads to wrist pain, numbness and weakness. Actually, it will make you feel very painful.

3. Smartphone pinkie

In recent years, it has been described that the little finger is deformed due to excessive use of mobile phones. This strange phenomenon, known as the "little finger" of smart phones, is becoming more and more common now, because from the development trend of mobile phones, they are getting bigger and bigger and need greater efforts to support them. Nowadays, photos of the little finger shrinking or bending in various strange ways can be found on social media.

4, SMS thumb

A study by Nielsen, a data analysis company, shows that British teenagers send an average of 3339 text messages every month. According to another research report of the British Office of Communications, 77% of children aged 12 to 15 spend about 12 hours playing video games every week. Combining these two activities requires a lot of thumb movement. SMS thumb usually refers to the injury caused by inflammation of tendon sheath. In some cases, this can lead to long-term pain and permanent injury of flexor digitorum longus tendon. To avoid this kind of injury, take a break while playing games and texting.

5, SMS neck

Wen Jing, also called Wen Jing, was invented by American chiropractors. This term is used to describe neck pain and repeated stress injury caused by frequent watching and using mobile phones. With the increasing popularity of smart phones around the world, this situation is also growing. Moreover, according to the latest data, 87% of teenagers in the United States own smart phones, while 79% of teenagers in Britain. Among adults, 92% of people in the United States have smartphones. Besides neck pain, it can also cause shoulder pain, upper back pain, headache and chest kyphosis.

6. Burn risk

Although this is a small probability event, we still need to pay attention to it. Because many people will overuse their mobile phones, and even watch them for a long time before going to bed, and then put them on their pillows. The mobile phone that is not turned off may still play TV movies after you fall asleep, which will cause continuous fever. In some small probability cases, there may even be an explosion. Last year, for example, a woman in Malaysia heard firecrackers in her sleep. Later, she found that her mobile phone exploded. After the explosion, her sheets and floor were burnt.

7. Computer vision syndrome

In fact, computer vision syndrome mainly refers to all kinds of poor eyesight symptoms of people who watch computers for too long. Such as inflammation, redness, dryness and blurred vision. But this is not only when you use the computer, in fact, using the mobile phone for a long time will have the same adverse consequences. The three main mechanisms leading to computer vision syndrome are extraocular muscle mechanism, accommodation mechanism and ocular surface mechanism. Brightness, resolution, glare and quality are all known factors that lead to computer vision syndrome. Obviously, controlling usage time is the most important strategy to avoid computer vision syndrome.

8, affecting sleep

Watching mobile phones before going to bed also has a very obvious negative effect, that is, it will affect sleep. Because the blue light emitted by the mobile phone screen will inhibit the production of melatonin, which is a hormone that controls the sleep-wake cycle. This makes it more difficult to fall asleep and wake up the next day. Circadian rhythm seems to be particularly sensitive to blue light because its wavelength is very short. Studies have also shown that exposure to blue light can damage the retina.
