VDT – SYNDROME ACQUIRED WHEN WORKING WITH PICTURE DISPLAY TERMINALS
- What is VDT syndrome?
VDT syndrome is a condition characterized by a range of physical and mental disorders that occur when you spend extended periods looking at a screen and typing on a keyboard. This condition is common among young people who spend a lot of time on computers, smartphones, and other mobile devices.
- Cause of VDT syndrome
Factors contributing to VDT syndrome include:
(1) Workplace factors: workstation design, seating, screen, keyboard, desk.
(2) Worker factors: age, physical condition, work habits, medical history.
(3) Environmental factors: vibration, lighting, noise, temperature, humidity, ventilation.
(4) Work factors: working posture, work intensity, working hours, rest periods.
- Symptoms of VDT syndrome
If you frequently use a computer or terminal and experience one of the following three symptoms, you may have VDT syndrome.
(1) Eye strain and frequent redness.
(2) Eyes sensitive or irritated by light.
(3) A feeling of having sand particles in the eyes.
- Treatment of VDT syndrome
The most effective treatment for VDT syndrome is exercise/mild physical activity. For computer users, it is recommended to focus on movements involving the wrists, neck, and shoulders. Even moving while sitting in a chair can be beneficial.
The movement method involves holding the correct posture for 8 to 12 seconds and repeating it 3 to 5 times. During stretching, exhale naturally. Perform these light exercises multiple times throughout the day whenever you have time.
(1) Press the palms together and lower them.
(2) Lift your chin and place both thumbs on your chin, tilting your head back as far as possible.
(3) Press the back of your hand: Extend one arm and press the back of your hand with the fingers pointing downward.
(4) Eye pressing: Rub your hands together as quickly as possible to generate heat, then place them over both eyes and slowly press your fingers around the pupils in a circular motion.
- Note about VDT syndrome
It is essential to find the correct posture to prevent musculoskeletal disorders such as stiffness, numbness, and pain in the back of the neck, shoulders, arms, hands, and fingers caused by VDT syndrome. Additionally, when working, it is advisable to position your hands on the desk to ensure that the height of the keyboard and elbows are level, reducing pressure on the wrists.
Furthermore, the distance from the screen to the eyes should be at least 50 cm, enough to reach the screen with your fingertips. When working on a computer, it is crucial to take regular breaks. Generally, you should take a 10-minute break after every 50 minutes of work.
