This is a common problem when you sit in front of the computer for a long time, because you sit for hours while using the computer. Your body has always maintained a posture, and it is inevitable that you will have backache and occupational diseases after working for a long time.

Generally speaking, computer diseases can be divided into two categories: physiological and psychological. The former includes "mouse hand", "keyboard wrist", neck and shoulder back pain, skin disease, nutritional deficiency, visual impairment, epilepsy and so on. The latter has many personality disorders, while others have physical and psychological diseases, such as "screen face" and obesity.

Because computer workers concentrate on the screen for a long time, the brightness of the computer screen remains unchanged for a long time, the handwriting is dense, and the indoor light is not suitable, which is easy to cause visual fatigue. If you don't pay attention to adjusting your eyesight at work, it will cause eye fatigue and decrease your eyesight. At the same time, computer operators have been engaged in data input and keyboard printing for a long time, and the amplitude of repeating a single action has not changed much, which requires considerable static support, which makes some neuromuscular tissues tense, which will cause inflammation and pain of tendons in hands, wrists, arms and even shoulders for a long time, sometimes involving tendon sheaths and muscle tissues.

Have posed

Personal seats should be adjusted to a suitable height so that people have enough space to stretch their legs and feet when sitting; Don't sit or stand too long;

When sitting, the back should be straight, close to the back of the chair, and don't cross your feet to avoid affecting blood circulation; When typing, the keyboard of the computer should be facing you. If you lean to one side, your wrist may be excessively bent and nervous. When typing, adjust the height of the keyboard and the parallel distance from the human body to a comfortable position.

Develop good health habits

Computer operators should not eat while operating the computer, nor should they eat in the operation room, otherwise it will easily cause indigestion or gastritis. Touch the computer keyboard too much, wash your hands after work to prevent infectious diseases.

Pay attention to keep your skin clean.

The skin of face and hands should always be kept clean, because there is a lot of static electricity on the surface of computer screen, and the accumulated dust will be transferred to the operator's face and exposed skin. If you don't pay attention to cleaning for a long time, it will easily lead to macula and pigmentation, and even cause skin lesions in severe cases, affecting beauty and physical and mental health.

Pay attention to the working environment

The light in the computer room should be suitable, neither too bright nor too dark, so as to avoid interference caused by direct light irradiation on the fluorescent screen. Regularly remove indoor dust and microorganisms, and it is best to use a wet cloth or a warm mop when cleaning. Disinfect the air filter, adjust the air volume reasonably and change the fresh air. If computer operation is carried out at home, protective screens should be arranged and used according to the above requirements as far as possible to minimize the harm of electronic radiation to human body.

Pay attention to the combination of work and rest

Generally speaking, computer operators should rest for about 1 0 minutes after continuous work. Moreover, it is best to exercise your hands, feet and limbs outside the operating room, take a walk, do radio exercises, take the initiative to rest, or do eye exercises and exercise your head indoors.

Pay attention to supplement nutrition.

Computer operators working in front of the screen for too long will consume rhodopsin on the retina, which is mainly synthesized by vitamin A. Therefore, computer operators should eat more foods such as carrots, Chinese cabbage, bean sprouts, tofu, red dates, oranges, milk, eggs, animal livers and lean meat to supplement vitamin A and protein in the human body.

Eye protection tips:

1. blink more when using the computer and rest every 1-2 hours 15 minutes.

2. The fluorescent screen should be under the line of sight.

3. In order to avoid reflection and unclear, don't put the computer on the opposite or back of the window.

Don't watch the computer in the dark, because black and white contrast is harmful to your eyes.

Some vision protection products will also help the eyes, such as various computer screens, which can reduce the radiation of computer screens and the stimulation to the eyes when computer screens flicker to some extent.
