How to sit in the correct posture while using a computer to maintain good health.

According to recommendations from the Bitkom High-Tech Association (Germany), an ergonomically designed workspace, whether in the office or for remote work, not only enhances comfort but also improves work efficiency.

Ergonomics principles are a set of rules and methods aimed at optimizing the interaction between people and their work environment, helping to reduce physical stress, improve performance, and ensure long-term health.

Ergonomics is widely applied in the design of workspaces, office equipment, and manufacturing tools to reduce the risk of injury and muscle fatigue caused by incorrect or repetitive working postures over long periods.

One of the most common health problems faced by office workers is back pain, which is also a leading reason for many people taking sick leave. The main causes of this condition often stem from a lack of exercise and the habit of sitting for long periods in front of a computer screen in an incorrect posture.

To minimize the risk of back problems and ensure a healthy work environment, Bitkom offers the following recommendations:

Adjust the height of the table and chair precisely.

Setting the appropriate height for your desk and chair is crucial for maintaining proper posture, reducing muscle tension, and preventing problems with your spine, shoulders, and wrists.

When making adjustments, you need to ensure the following factors:

The natural right angle of the body:The thighs and lower legs should form an angle of approximately 90 degrees, with the feet flat on the floor or on a footrest if needed. Similarly, the upper arms and forearms should also form a right angle when resting on a desk.

Keyboard and mouse placement:The keyboard and mouse should be placed on the same surface, at elbow level. When typing or using the mouse, the palm should be kept relaxed, and the wrist should not be excessively bent to avoid carpal tunnel syndrome.

Seat height:Adjust your chair so that your spine is well supported, with the backrest supporting the natural curve of your spine. If the chair has armrests, make sure they are not too high or too low to avoid straining your shoulder muscles.

By adjusting the height of your desk and chair correctly, you will create a comfortable working posture, reduce stress on your body, and enhance concentration and work performance.

Sit in a flexible position to protect your health.

Maintaining a flexible posture while sitting at work helps reduce pressure on the spine, improves blood circulation, and limits the risk of muscle pain from prolonged sitting. A properly designed office chair not only supports the back but also allows the body to move naturally throughout the workday.

Here are some important factors to keep in mind when sitting at a desk:

The seat is highly adjustable:Choose a chair with adjustable height to suit your leg length, ensuring your feet rest firmly on the floor without putting pressure on your thighs or calves.

Backrest that supports the spine:A chair with a flexible backrest that can be slightly tilted and adjusted in height will help support the lower back, maintain the natural curve of the spine, and reduce strain on the lower back.

Flexible movement:Avoid sitting in one position for too long. Take advantage of the chair's tilt and swivel features to gently change your posture, helping to prevent muscle stiffness. Sometimes, leaning slightly back or shifting your weight can help reduce pressure on your back.

Foot support:If your feet don't fully touch the floor, use a footrest for a stable support. This is especially important for smaller people, helping to prevent their feet from dangling and causing muscle fatigue.

Position your body correctly:When sitting, keep your head straight, shoulders relaxed, and arms comfortably resting on your desk. Avoid leaning forward or reclining too deeply in your chair, as this can put unnecessary strain on your neck and back.

By adopting active sitting principles, you can minimize health problems associated with desk work while maintaining better focus and productivity.

Maintain a safe distance from the screen to protect your eyes.

The distance between your eyes and the screen is a crucial factor in reducing visual strain, minimizing eye fatigue, and avoiding posture-related problems. Sitting too close or too far from the screen can lead to eye strain, dry eyes, or even neck and shoulder pain due to improper posture adjustments.

Here are some specific guidelines to ensure a proper distance between your eyes and the screen:

Minimum distance:Desktop PC users should maintain a distance of 50 cm to 70 cm between their eyes and the screen. This helps reduce eye strain when viewing content on the screen.

Larger screens require a greater viewing distance:For larger screens, such as 27 inches or more, the viewing distance should be increased to approximately 75 cm to 90 cm to avoid the need for constant eye movement and adjustment.

Adjust the screen settings accordingly:

Position the monitor at eye level or slightly lower (about 10-15 degrees below the straight line of sight) to reduce strain on your neck.

Tilt the screen slightly at an angle of 10-20 degrees to reduce light reflections and optimize the viewing angle.

Ensure the screen is neither too bright nor too dark to avoid eye strain from constant adjustment.

Apply the 20-20-20 rule: Every 20 minutes, look at something about 6 meters away for 20 seconds to help your eyes relax and avoid digital eye strain.

Maintaining the correct distance when working with a screen not only helps protect your eyes but also contributes to improved posture, minimizing the risk of neck, shoulder, and back pain caused by improper posture.

Proper lighting is essential for eye protection and increased work efficiency.

Lighting is a crucial element in the workspace, directly impacting visual health, concentration, and productivity. A suitable lighting system helps reduce eye strain, minimize glare, and create a more comfortable environment for extended computer use.

Ideally, your workspace should be positioned to receive sufficient natural light, which is more comfortable for your eyes than artificial light. However, avoid placing your monitor directly opposite or behind a window, as this can cause glare or reflections on the screen, requiring your eyes to strain more.

By arranging the lighting properly, you can help keep your eyes comfortable, reduce fatigue, and maintain higher work efficiency.

Maintain physical activity to protect your health.

Sitting for long periods not only causes fatigue but also increases the risk of spinal, circulatory, and overall health problems. To maintain good physical condition and mental clarity throughout the workday, proactively move around and incorporate physical activities into your routine.

Avoid sitting in one place for too long:Try to change your posture frequently, standing up and moving around every 30-60 minutes to avoid muscle stiffness and reduce tension in your back, neck, and shoulders.

Take advantage of short workouts:Perform some stretching exercises, extend your arms, or take a short walk around the office. These exercises help stimulate blood circulation, reduce muscle tension, and improve overall flexibility.

Remember that exercise not only improves physical health but also boosts energy and productivity every day.

Work efficiently and comfortably with laptops and tablets.

In the age of mobile technology, more and more people are using laptops and tablets for work, instead of traditional desktop computers.

However, due to their compact design, these devices often have small screens and fixed keyboards and mice, which restricts working posture and can cause strain on the body when used for extended periods.

To minimize negative health impacts and ensure a more comfortable working posture, the Bitkom High-Tech Association recommends:

For laptops:

When using it as a stationary device, connect an external keyboard and mouse to avoid wrist strain and reduce pressure on your shoulders.

If possible, use an external monitor and position it at eye level to avoid excessive head bending, which can reduce strain on the neck and back.

If you don't have an external monitor, use a laptop stand to adjust the screen height, combined with a separate keyboard, to maintain proper working posture.

For tablets:

Use a monitor stand to adjust the viewing angle to a comfortable position, avoiding having to bend your neck for extended periods.

Combine it with a detachable keyboard to increase typing comfort, allowing your wrists and arms to be in a more natural position.

If using a stylus, place the tablet on a surface with a slight incline to reduce pressure on your wrist and shoulder.

Implementing these measures will help optimize working posture, reduce the risk of back pain, eye strain, and muscle tension, and improve work efficiency even when using mobile devices.
