How to prevent four major occupational diseases: mouse hand, mobile phone elbow, keyboard wrist and screen face?

The range of wrist flexion is about 70O~80O on the palm and 50O~60O on the back of the hand. When using the keyboard, the wrist flexes about 45O~55O, which is close to the maximum angle, and will pull the tendon in the carpal tunnel to make it in a high tension state. In addition, the palm root will press the carpal tunnel on the desktop. In this state, repeated movements of fingers can easily damage tendons and nerves. When people use the mouse, they will mechanically focus one or two fingers repeatedly, and with this monotonous and slight activity, they will also strain the ligament of their wrists. Causing peripheral nerve injury or compression.

Countermeasures: Get up and move every hour of work, do some fists and fingers, and relax your hands. When using a computer, the height of the keyboard and mouse on the computer desk should be lower than the elbow height when sitting. Don't hang down your arm when using the mouse. When moving the mouse, don't use wrist strength, but try to do it through arm strength. Don't hit the keys of the keyboard and mouse too hard. In addition, it is best to choose a mouse with large radian and wide contact surface, which will help to disperse the force.

Disease 2: mobile phone elbow

"Cell phone elbow" is called "cubital tunnel syndrome" in medicine. Most people suffering from "cell phone elbow" are white-collar workers, who spend more than four hours answering their cell phones and sending text messages every day. It is understood that the early manifestations of "mobile phone elbow" are fatigue, numbness and pain in the elbow joint, and sometimes the arm cannot be raised. Because it takes too long to answer the phone, the arm always turns in circles when making a phone call, which will cause nerve traction injury for a long time. Severe symptoms are persistent pain, arm weakness and even objects falling off. When the front arm rotates and stretches forward, it is often limited by pain.

Countermeasures: Experts suggest that people who often use mobile phones should try to use headphones when making calls to avoid long-term bending of their arms, or try to "open the bow left and right" and let their hands take turns to relax and rest. Generally, you should exercise properly after the phone call, and you can also use a towel to relieve muscle tension. Experts remind that if you find that the frequency of symptoms such as arm pain and numbness is increasing, or such symptoms appear in a short time, you should go to the hospital immediately.

Disease 3: keyboard and wrist

Medically, it is called carpal tunnel syndrome. The main symptoms are numbness and pain in the wrist, thumb, index finger and middle finger. The thumb is often clumsy and weak, and the thumb, index finger and middle finger feel dull and abnormal, while the inner half of the little finger and ring finger are completely normal. If the patient puts his hands on the table, his forearm is perpendicular to the desktop, and his wrist naturally bends his palm and droops, numbness of the index finger and middle finger will appear after about one minute. Mainly engaged in computer typing and keyboard tapping for a long time.

Countermeasures: People who use computers for a long time should be allowed to pad their wrists to avoid sagging wrists. After working for about an hour, you should have a rest and exercise your wrist. We should temporarily stop using the computer during the treatment and follow the doctor's advice through physical, closed and surgical methods.

Disease 4: Screen face

People who deal with computers every day, facing the computer screen for a long time, will unconsciously give birth to a face with cold expression, which will affect daily interpersonal communication and easily lead to personality disorder and personality abnormality. Long-term man-machine conversation will lead to the situation that facial expressions are not rich or even expressionless and indifferent. In addition, screen radiation will generate static electricity, which is the easiest to absorb dust. When you face each other for a long time, spots and wrinkles are more likely to occur.

Countermeasures: When operating the computer daily, the distance between the body and the computer screen should be no less than 70cm. The hardware should be equipped with a computer with small radiation, no glare and stable display, and the LCD screen is better. At the same time, you should choose a computer desk and chair that suits you, and try to adjust it to the state that suits you best. Pay attention to eye rest, preferably every hour 10 minutes, and do eye exercises twice a day. The first task after surfing the Internet is to clean the skin, thoroughly clean the face with warm water and cleansing liquid, wash away electrostatic dirt and apply mild skin care products. Long-term use can reduce injury, moisturize and beautify.

The phenomenon of "computer face" of white-collar workers who are not used to face-to-face conversation is serious.

According to a survey, more than 60% white-collar workers in Shanghai work at their desks until late at night every day, and 80% of them suffer from different degrees of brain fatigue due to long-term excessive use of their brains.

I have a "computer face".

"I have been facing the computer for a long time, and my face feels like ice, which is a bit dull." Soso, who works in the IT industry, felt uncomfortable for the first time on the way to the bathroom. Colleagues from neighboring departments greeted him, and Soso smiled back. "The other party looked at me strangely for a long time, and I still feel puzzled. I quickly smiled at the mirror again, and I was stunned at that time. " Soso said he found his smile fake. For young white-collar workers like Soso, the normal behavior mode is "man-machine dialogue", but there will be psychological obstacles when returning to "everyone dialogue". Psychologist Fei Jia analyzed that long-term working in the computer "instruction-execution" thinking mode, these people often grow into "computer faces", which will appear dull in real interpersonal communication.

"I start thinking about the case at hand in the blink of an eye every day, and I have to fight until two or three in the morning almost every day." Eric is a management consultant of a business consulting company. Due to stress and excessive use of brain, Eric changed from gastric ulcer to hair loss. There is also a new term: "Tsukuba disease". This refers to hallucinations, unresponsiveness, dizziness, etc. caused by people receiving excessive information and overloading their brains. Liu Wei is a public relations officer in the construction industry. He browses a lot of online information every day to ensure that he keeps pace with the times.

"Many times, I am not in a hurry to receive emails, but I always want to open my email without being controlled by my brain, just like I always feel safe when I am habitually surfing the Internet."

White-collar patients account for 70%

Every morning, two long chairs outside tongji hospital's psychosomatic department are full of people. Nurses in this department said that the patients who came to see a doctor were getting younger and younger, and some patients in neurology department had been transferred to psychosomatic department, many of whom were white-collar workers. "The peak of brain fatigue and psychological problems of white-collar workers is generally at the end of the year, and many white-collar workers are anxious because of job-hopping and work. Cui, deputy director of psychosomatic medicine, said: "At present, there are quite a lot of people in the psychological clinic, and sometimes more than 80 people have to watch it for half a day." White-collar workers account for 70% of anxiety patients who come to see a doctor. "In the psychosomatic inpatient department, the reporter met many young people. Cui said that most white-collar workers who come here for hospitalization are anxious and depressed. Many white-collar workers are generally in sub-health state, and their brains are overtired, which leads to insomnia. Persistent insomnia leads to impulsiveness and frequent temper tantrums, followed by forgetfulness and low work efficiency, thus forming a vicious circle.
