Radiation of the hazards of computer vision syndrome
A, radiation of the hazards of computer vision syndrome
The U.S. agencies announced two survey results show that long-term use of computers will make people's eyes appear a variety of uncomfortable symptoms, ophthalmologists and optometrists will be referred to as the "computer vision syndrome ". Health care experts believe that operating a computer is a fairly concentrated vision work, will reduce the secretion of lubricants and enzymes in the eye. In general, if a person blinks less than five times per minute. And if it lasts for a longer period of time, it will make the eyes dry and tired, with symptoms such as double vision, blurred vision as well as head and neck pain. Ophthalmologists warn computer users that after using a computer for one to two hours (60 percent of which is spent gazing at a fluorescent screen), it is important to do something else to give your eyes a break. When eye problems do not go away naturally, you should go to the hospital for a checkup. In order to avoid reflections and lack of clarity on the screen, wear anti-radiation glasses to protect your eyes, as well as computers should not be placed on the opposite side of the window or at the back, and should avoid or minimize the glare on the screen as much as possible. Do not operate your computer in the dark, as the black and white contrast can be harmful to your eyes. The place where you sit should be as comfortable as possible. If possible, you should use a chair with an adjustable backrest.
Second, the harm of radiation of the carpal tunnel syndrome
Carpal tunnel syndrome
Radiation of the harm of the carpal tunnel syndrome
Prolonged use of computers, some people's hands will be pain and paroxysms of numbness, accompanied by swelling of the carpal joints, hand movement inflexibility, weakness of the hands and other symptoms, and there is a tendency to aggravate, which is known as the medical " Carpal Tunnel Syndrome". Prevention of carpal tunnel syndrome, self-care is a more effective method, usually should develop a good sitting posture, regardless of work or rest, should pay attention to the posture of the hands and wrists, to try to keep the wrist straight, do not bend. But do not overstretch. Ambulatory staff, should be adjusted to the height of the chair, sit down when the feet can just flat on the ground. Computer operators can use wrist rests if necessary. Do not tilt your head forward. Keep your upper body straight and do not bow your head. Every 0.5 to 1 hour, you should stand up and take a break, shake your hands, stretch your fingers, make a fist and relax. Once you have carpal tunnel syndrome, there is no need to be overly nervous. For patients with mild early symptoms. Local closure and physical therapy can often achieve better results. Treatment should initially allow the wrist to rest a lot, and if necessary, the wrist can be immobilized with a plaster splint to keep it straight. The doctor may also give anti-inflammatory and analgesic substances to help the symptoms subside. In severe cases, a localized cortisone injection may be given into the wrist to control pain and swelling. If these methods do not work or if atrophy of the piriformis muscle (the full muscle that protrudes from the base of the thumb in the palm of the hand) has occurred, surgery is needed to relieve pressure on the median nerve.
Three, the harm of radiation cervical spine syndrome
Disease
Young people sitting in front of the computer longer and longer, long time posture is very easy to lead to cervical spondylosis. Spinal subluxation not only makes the joints lose function, affecting the flexibility, so that the muscles tighten severe pain and fatigue, and may even cause muscle atrophy, due to the spinal nerve compression, the serious will lead to the heart and lungs, and other organs continue to decline in function. In domestic medical institutions, there are many spinal diseases and treatment programs, such as massage, acupuncture and physiotherapy, objects, traction, surgery, etc. Patients can choose the treatment according to the doctor's recommendations, combined with their own state. Application of spinal biomechanical principles, combined with traditional manipulation of chiropractic treatment of spinal disease, treatment time is short, less pain, quick results, patients are happy to accept.
Four, the harm of radiation of the "computer face"
The harm of radiation of the "computer face"
Psychology experts found that people who often deal with computers, due to the prolonged face of the lifeless Computer screen, less and less communication with people, will unknowingly produce an expression of indifference, cold face, and will affect the daily interpersonal communication, and then produce psychological and mental disorders. According to medical research, where the face with a smile, eyeballs, flexible, glowing eyes of the baby, the body's iron storage most of the normal. On the contrary, the face is serious, dull or 1 hour only laugh 1 to 2 times of the baby, the blood iron content may be insufficient. If in a week of continuous iron, serious expression will gradually disappear and replaced by a pleasant look; experts suggest that those who do not smile "computer face", may wish to choose to supplement the iron, in order to change the stereotypical face.
Fifth, the hazards of radiation computer thrombosis
"Computer thrombosis" is actually the medical venous thrombosis. Computer operators due to sedentary, lack of exercise, coupled with more in the air-conditioned environment, do not pay attention to timely supplementation of water, blood viscosity will increase, greatly increasing the risk of thrombosis. "Computer thrombosis" is similar to the so-called "economy class syndrome", the early symptoms are spontaneous leg and stomach pain, swelling, localized fever, walking pain, and even cause the inability to walk. If venous thrombosis is not treated in time, it can lead to lower extremity venous occlusion and destruction of venous valves, and deep venous embolism can lead to the gathering of clots to the lungs and induce pulmonary embolism, which can be life-threatening in severe cases. So people in front of the computer office, every once in a while to stand up and walk, drink more water, do more calf and foot stretching exercise, which can effectively prevent this disease.
Six, the harm of radiation of the computer radiation alopecia
The harm of radiation of the computer radiation alopecia
The longer the contact and use of the computer, the stronger the radiation produced by the human body, one of the main side effects of radiation is that it will make people's hair fall out. In addition, computer workers use the brain for a longer period of time, the attention is highly concentrated, will make the excitability of the brain continues to increase, and the endocrine function related to the growth of hair disorders, sebaceous gland secretion, the hair follicle is easy to be embolism, which will make the hair of the nutritional supply of the obstacle, leading to hair brittleness increase and happen to fall off. Therefore, the key to preventing hair loss in the scientific use of the brain, at the same time, the installation of computer fluorescent screen shield, adjust the time to use the computer, to ensure adequate sleep, head of good habits, reasonable adjustment of dietary structure, scientific care of hair.
"There is a healthy body, only the capital." Visible health is how not to be ignored. I hope that everyone through this article are aware of the hazards of radiation triggered by the symptoms! So for the sake of our health, we should take protective measures to reduce the harm of electromagnetic radiation on us. More details of the decoration strategy, please continue to pay attention.
