Lead to endocrine disorders
Hui Jin, chief physician of endocrinology department of Zhong Da Hospital affiliated to Southeast University, said that some studies have found that using electronic products such as mobile phones and tablet computers two hours before going to bed will inhibit melatonin secretion and cause insomnia, which will lead to endocrine disorders in the long run. The common manifestation is acne on the face, which may even lead to metabolic diseases such as diabetes.
Injured cervical vertebra
Professor Wu Xiaotao, director of spine surgery in Zhong Da Hospital, pointed out that looking down at mobile phones for a long time is an important reason for the rejuvenation of cervical spondylosis. If you bow your head for too long, the pressure on the cervical spine will increase, which will lead to changes in the flexion of the cervical spine, which will easily lead to cervical disc herniation and cervical instability.
Injured lumbar vertebra
Wu Xiaotao said that there are still people who like to play with their mobile phones while lying half-lying, which will hurt their lumbar spine. Because in the semi-supine position, due to the lack of adequate support, the original curvature of the lumbar spine will change, so that the gravity on the intervertebral disc will continue to increase, and over time it will induce disc herniation.
Cause the neckline to "climb"
Zhang Jue, an attending physician at the Plastic Surgery Center of Zhong Da Hospital, said that when playing mobile phones, the pressure on the human neck is greater than usual, and the neck muscles grow vertically, which makes it easy to sag. In addition, lower head extrusion will shorten the neck muscles, lead to accelerated aging of epidermal cells and deepen neck wrinkles.
Cause skin allergy
Dong Zhengbang, an attending dermatologist in Zhong Da Hospital, said that some people may suffer from contact dermatitis when they touch mobile phones. Because some people may be allergic to metals, rubber, etc. And many mobile phones are often made of these materials, so mobile phones are likely to become allergens. In addition, contact with mobile phones is also a kind of irritation to the skin. With the increase of answering time, the temperature of the mobile phone itself rises, which may aggravate skin problems such as acne and acne.
Hurt the eyes
Ray, the attending ophthalmologist of Zhong Da Hospital, said that for children, watching mobile phones at close range for a long time will keep their eyes in a state of tension and fatigue, and they will not get enough rest, which will easily lead to myopia. For adults, staring at the screen for a long time will reduce the number of blinks by 1/3, which will lead to more tears evaporation on the eyeball surface and make the eyeball lack of water. The evaporation of tears is one of the main causes of dry eye. Dry eye will eventually lead to permanent eye damage.
Induced tenosynovitis
Kong, deputy director of the Department of Orthopaedics, Zhong Da Hospital, said tenosynovitis is common in middle-aged and elderly people, but for young people, playing mobile phones for a long time can also cause tenosynovitis, with symptoms including finger, wrist and forearm pain and spasm. In addition, if the mobile phone is much larger than the palm, the thumb will remain abduction for a long time, and the whole palm will exceed the functional position. If it takes a long time, it will cause strain on hands and wrists, and there will be symptoms such as numbness and weakness in hands.
Leading to "digital dementia"
Yuan Yonggui, director of the Psychiatry Department of CUHK Hospital, said that if we rely too much on digital products such as mobile phones, such as frequently swiping Weibo, reading friends and browsing the web, a lot of invalid information will enter the brain, which will weaken the brain's ability to process useful information and eventually lead to memory decline, leading to "digital dementia".
