Ergonomics in the workplace is a key element affecting the health, comfort and productivity of employees. Providing the right working conditions can significantly reduce the risk of physical ailments, such as back, wrist and neck pain, and improve overall quality of life and job satisfaction. In this article, we will discuss what ergonomics is, what its principles are, what ailments can result from a non-ergonomic work environment, and what steps can be taken to improve ergonomics in the workplace.

   1. What is ergonomics?

   1.1 Definition of ergonomics

  Ergonomics is the science that deals with the adaptation of working conditions to the psychophysical capabilities of humans. The goal of ergonomics is to design workstations, tools and tasks in such a way as to minimize the risk of physical ailments, fatigue and increase the comfort and productivity of workers.

   1.2 History of ergonomics

  Ergonomics as a science gained prominence in the 20th century, especially during World War II, when attention began to be paid to adapting workstations to the needs of soldiers and industrial workers. Modern ergonomics combines knowledge from various fields such as engineering, psychology, anatomy and medicine to create optimal working conditions.

   2. Ailments resulting from non-ergonomic work environments

   2.1 Back pain

  One of the most common problems resulting from an unergonomic workstation is back pain, especially in the lumbar and cervical regions. Prolonged sitting in the wrong position, lack of proper support for the spine, and improper monitor and chair positioning can lead to muscle tension and pain.

   2.2 Wrist and hand complaints

  An unergonomic workstation can lead to wrist and hand ailments such as carpal tunnel syndrome, tendonitis and joint pain. Improper positioning of the keyboard, mouse and lack of proper wrist support can contribute to these problems.

   2.3 Neck and shoulder pain

  Prolonged sitting in the wrong position and improper monitor positioning can lead to muscle tension and pain in the neck and shoulder area. Lack of proper shoulder support and too high or too low a monitor position can cause discomfort and discomfort.

   2.4 Eye fatigue

  Inadequate lighting, being too close to the monitor and looking at the screen for long periods of time can lead to eye fatigue, dryness, burning and headaches.

   2.5 Circulation problems

  Sitting in one position for long periods of time without adequate breaks for movement can lead to circulation problems such as swollen legs, varicose veins or thrombosis.

   3. Ergonomic principles in the workplace

   3.1 Ergonomics of the workstation

  Adapting the workstation to the needs of the employee is key to ensuring comfort and health.

    3.1.1 Chair

    - Lumbar support: The chair should have lumbar support that supports the natural curvature of the spine.
    - Footrests: The chair should have armrests that support the arms and reduce muscle tension.

    3.1.2 Desk

    - Desk Height: The desk should be high enough so that the forearms form a right angle with the shoulders when working on the keyboard.
    - Desk Surface: The surface of the desk should be large enough to accommodate all the necessary work tools such as computer, documents and other accessories.

    3.1.3 Monitor

    - Monitor Height: The top edge of the monitor should be at eye level or slightly below to avoid excessive leaning forward.
    - Distance from monitor: The monitor should be positioned about 45-70 cm from your eyes to ensure comfortable vision.
    - Tilt angle: The monitor should be tilted slightly backward to reduce glare and improve comfortable vision.

    3.1.4 Keyboard and mouse

    - Keyboard Position: The keyboard should be in line with the forearms to prevent excessive tension on the wrists and hands.
    - Mouse: The mouse should be placed close to the keyboard to avoid excessive arm and wrist extension.

   3.2 Ergonomics of lighting

  Adequate lighting is key to working comfort and preventing eye fatigue.

    - Natural light: If possible, your workspace should be well lit with natural light. Avoid placing the monitor directly in front of a window to avoid glare.
    - Artificial lighting: Use artificial lighting of appropriate brightness and color. A desk lamp with an adjustable arm can help customize the lighting.
    - Avoiding glare: Avoid glare on your monitor screen by using matte screens, curtains, blinds or anti-glare filters.

   3.3 Ergonomics of movement

  Regular movement breaks and repositioning can significantly reduce the risk of physical ailments.

    - Movement Breaks: Plan regular movement breaks every 30-60 minutes. Stand up, stretch, take a few steps to improve circulation and reduce muscle tension.
    - Use ergonomic tools: Use tools that promote healthy posture and movement, such as footrests, seat balls and adjustable desks.

   4. Prevention techniques to prevent workplace ailments

   4.1 Stretching and exercise

  Regular stretching and exercise can help maintain muscle flexibility and prevent strains.

    - Neck and shoulder exercises: Perform stretching exercises for the neck and shoulders, such as gentle twists and head bends.
    - Exercises for the spine: Perform exercises to strengthen your back muscles and stretch your spine, such as kitten curls, trunk twists and hip bridges.
    - Wrist exercises: Perform wrist exercises such as wrist rotations, finger and wrist stretches, and wrist circles.

   4.2 Relaxation techniques

  Relaxation techniques can help reduce muscle tension and stress.

    - Deep Breathing: Use deep breathing techniques regularly to calm the body and mind.
    - Meditation: Use meditation or mindfulness techniques to reduce stress and improve concentration.
    - Progressive muscle relaxation: Practice progressive muscle relaxation by tensing and relaxing different muscle groups.

   4.3 Regular health checkups

  Regular health checkups can help detect and treat work-related health problems early.
