Smartphone does not deny being one of the most useful inventions of mankind. It changes the way life works, making things easier. You can call a car, order food, transfer money, pay bills, make silver billions transactions … with just a few claws.
But the convenience of smartphones also makes people become increasingly dependent on it, even abuse to the point of becoming addicted. Usually anything "too" is not good, and with smartphones, it brings 5 diseases that are happening to many people today.
1. Syndrome … horns
Recently, experts from the Sunshine Coast University (Australia) conducted a study on 1,200 young people between the ages of 18 and 30 years old. They tracked the X-ray of the candidates' skulls, and found a very unexpected phenomenon: About a third of them had a bone spine growing from behind the skull, looking like like a small horn.
The reason is attributed to the habit of tilting the head forward when using smartphones and other portable electronic devices. This action causes weight to shift from the neck vertebrae to the back muscles, causing the skull to grow more bone to relieve pressure.
This can be compared with the phenomenon of skin that grows into bottles when constantly under pressure from external environment.
Usually, this bone is only hidden inside the head, but there are some cases where they feel they have it. And even though it has not been recorded yet, it is a fact that people today are using too many phones.
To avoid a "horny" day, always sit up straight, avoid bending over when using the phone, and remember that after 1 hour it is necessary to rest your body.
2. Syndrome "Stock Message" (Text-neck)
The crouching posture when using the phone not only causes you to grow horns, but also causes bad effects on the back and neck. The most typical consequence is the "stock message" syndrome.
Specifically, a recent study by spinal surgeon Jason Cuellar and Todd Lanman from Cedars-Sinai Medical Center (Los Angeles, USA) has shown that we are inclined to bow too much when using Use the phone, with a forward curve of about 45 degrees. This number is even more terrible – up to 50, 60 degrees when using the phone while sitting.
Lanman said, in a straight neck position, our head is subjected to pressure of about 4-5 kg. But just bending down 15 degrees, the pressure was up to 12kg. And when tilting 60 degrees, that's 27kg.
So what to do? Doctors believe that the best advice at this time is to reduce the frequency of using the phone down, while enhancing the breaks during use. Also, practice the exercises to improve the strength of the neck and shoulder muscles.
In addition, Lanman thinks that while sitting and using the phone, at least put your elbows on the table, putting the phone at eye level. That posture is good for the neck, and reduces the pressure on the shoulders and arms.
3. "Texting thumb" syndrome (Texting thumb)
In fact, this disease has not had an official diagnosis, but there are many people who recorded the same symptoms, so they gave it that name.
This is a syndrome that makes people feel painful, uncomfortable by pressing and swiping the screen too much, causing a thumb and thumb under the hand. There are even severe cases that require surgery – as noted by doctors at Rush University (Chicago, USA).
Medicine has not yet recognized the connection between this disease and excessive phone use. However, some chueyen suggest that if you see similar symptoms, you need to use your smartphone more moderately, give your fingers more rest, and regularly do stretching movements every time. tired.
4. Computer vision syndrome (Computer vision syndrome)

According to scientists, the culprit causing this "ghost phone" phenomenon is called "Phantom Vibration Syndrome" (PVS).
Researchers from Massachusetts of the United States hypothesize that these false signals "may be the result of cortical sensory signal processing".
They said that the busy people often communicate by phone, the brain will often misunderstand the meaning of the information such as rubbing clothes into the body, stimulating other perceptions … virtual The phone vibrates.
