Some serious health problems I might have to get a job require sitting in front of a computer screen 9 hours each dayFirst: Repeated pressure damage (RCI):Also known as Work Related Upper Limb Disorder WRULD is a non-medical concept used to express a range of stresses that a person experiences as a result of repetitive performance of the same work, especially with inappropriate posture for a long period of time. Which leads to damage tendons, nerves, muscles and other body tissues Soft body tissue.Some symptoms and signs of repetitive stress.1. CTS Carpal Tunnel Syndrome.The production of oxygen without the presence of oxygen, which produces lactic acid and other products to accumulate in increasing quantities causing fatigue in the muscle and then move the effect to the cells Which leads to the continuation of oxygen causing the bulge of the muscle that presses the central nerve, which works on the delivery of nerve indicators and thus the atrophy of the muscles of the forearm and loss of control over the performance of movements of the fingers and a sense of numbness and pain and less Motor range of the wrist.Symptoms:- Tingling in the fingers of the first three hands and part of the palm with a cold in the hands.- Pain in the wrist, hands and fingers.-2. Muscle tendon injuries: 1-Tendonitis Tendonitis:The increased tension on the tendon results in inflammation, where the tendon fibers begin to gradually separate until they rupture causing a large friction leading to swelling and a feeling of pain.(Sub-acute Tendonitis) is the most common, which causes chronic pain in the wrist and forearm and worsens the condition of the activity.2-myocardial tendonitis Tenosynovitis:Which occurs as a result of moderate or intermittent activity that does not reach the extent of causing acute inflammation, but affects the ability of the sheath to lubricate the tendons leading to increased thickness of the sheath and inflammation causing pain.Symptoms:Pain when the movement of fingers and pain in the hands and joints may develop into severe pain in the forearm.II: Optical Stress (EYE STRAIN) (ASTHENOPIA)70% of those sitting in front of the computer screens suffer from pain in the eye area "Dr. Janet Focke" Safety and Occupational Health 1998, results from staring for long hours in computer politicians with the reduction of eye blink BLINKING, which leads to dry eye and with time cause confusion and deterioration of vision Especially those who did not suffer from previous visual problems in addition to the pain of the head.Symptoms:- Heartburn and itching in the eye.Optical fatigue.- Distorted vision and problems in color perception- In addition to the deficiency of the eye, which leads to tension and permanent headache.This problem develops to cause pain in the head, fatigue and difficulty concentrating.Third: Neck and Back PainIt is the most common cause of low work efficiency, as 30% of adults suffer from it and are spread among people whose work nature requires sitting for a long time behind the computer.In the case of computer use we find that it requires staying stable for a relatively long period during the working period, especially with low level of fitness. Which causes straining the neck and back as a result of continuing to lift and lower the head for a clearer vision.Symptoms:- These pains cause inability to sleep and perform homework or carrying children.Fourth: headache Headache is divided into two types:1. Tension headache: - is the most common - and occurs as a result of the long contraction of muscles in the shoulders or neck or face or scalp, which leads to pressure on the blood vessels and thus block blood flow, which leads to lack of oxygen in the muscles.The tension headache is usually lumpy and non-pulsating at the beginning and starts from the back of the head and crawls forward to give birth to a sense of strong pressure at the front of the head or forehead as if the person put a hat very narrow, most of these types of headaches may stop on their own after a few hours Continue for days. Factors such as stress and anxiety when using the computer lead to this headache.2. Headaches: - In this type of blood vessels in the brain to the sudden expansion, which stimulates and irritates the surrounding nerves and shows the pulsating pain that distinguishes the sister and hit one side of the head more than the other and lasts between an hour and 72 hours may be launched from the front area around One of the eyes or the temples or near the ears or the jaws and pain may affect the muscles of the shoulders and neck. The headache may be accompanied by nausea, vomiting, diarrhea, dizziness, numbness in the face, chills or coldness in the hands and feet, and the sister is exposed to factors such as physical stress.V. DEPRESSION:Is one of the symptoms that are beginning to appear significantly in the present time in conjunction with the widespread spread of the Internet. Recent studies show that there is a significant correlation between the time consumed during the use of the Internet and the high frustration of those individuals, which led to the belief that the person who spends long hours online Increasingly, excessive use of computers reduces the time available for normal social relationships and reduces the chances of family reunion, leading to frustration. Sixth: Electromagnetic radiationThis issue has sparked widespread debate about the impact of electromagnetic radiation on health, because continuous exposure and a relatively long period of time of radiation as in areas of high pressure lines lead to health problems.But there is no evidence that the weakest radiation from computer screens causes birth problems, breathing problems, heart palpitations and dizziness.
