The art of considering human physical and psychological needs.

What is ergonomics?

Ergonomics is a science focused on optimizing the interaction between humans and their activity. It explores how to improve work environments and conditions so they align with human physical and psychological needs. The word comes from the Greek ergon (“work”) and nomos (“law” or “science”), literally meaning “the laws of work.” As an interdisciplinary field, ergonomics combines various scientific and engineering principles to reduce injury risk and enhance work efficiency.

This discipline includes a range of methods and tools to assess what a workplace, machinery, and equipment should be like to ensure healthy and comfortable working conditions. Through studying work environments, ergonomics establishes standards and regulations designed to reduce stress, fatigue, and health issues.

Ergonomics began to develop in the mid-20th century, though its roots go back to ancient civilizations. For example, in Ancient Egypt, attention was already given to work organization and tool design. Later, during the Industrial Revolution in the 18th century, interest in improving work efficiency grew, as it increased productivity.

In the 20th century, ergonomics became a formal science thanks to advances in technology and research into human physiology and psychology. Researchers and engineers began studying factors affecting human movement, psychological impact, and biomechanics to improve work environments. Since then, ergonomics has emerged as a specialized scientific field.

The Role of Ergonomics in the Modern World

In today’s world, ergonomics plays a vital role not only in increasing productivity but also in preserving human health and wellbeing. Challenging working conditions, long office hours, the presence of technology, and modern life stressors all raise the risk of health problems—especially those related to muscles, joints, and the nervous system.

Thus, ergonomics is essential for:

• Preventing injuries and fatigue,
• Enhancing worker efficiency,
• Designing more intuitive and user-friendly technologies and equipment.

As a result, ergonomics is not merely a science, but also an art that seeks to harmonize human needs and productivity by providing solutions that support physical health and psychological balance.

Theoretical Foundations of Ergonomics

Ergonomics is based on several core principles aimed at creating a healthy, efficient work environment:

• Comfort: The workplace and tools should be designed to support physical comfort, reducing muscular and nervous strain and preventing health issues.
• Safety: Ergonomics aims to ensure safe work environments. Workers should feel secure, which decreases both physical injuries and stress. Equipment placement, usage guidelines, and the overall environment significantly influence safe work.
• Efficiency: Ergonomics relates to quality and speed of work by applying methods that help people perform tasks without extraneous effort or wasted time, boosting productivity.
• Individualization: Considering each person’s physical and psychological traits. Ergonomics strives to create environments that meet diverse needs, accounting for age, physical fitness, and mental state.
• Interface simplicity: Tools and tech devices should be easy and intuitive to use, minimizing errors and allowing focus on main tasks.

Types of Human Needs: Physical, Psychological, and Social

Ergonomics studies human needs to ensure that work environments satisfy them:

• Physical needs: The body operates best in environments without added pressure or tension. Factors like posture, lighting, ventilation, temperature, and workspace layout are essential for physical wellbeing. For example, ergonomic chairs and desks reduce strain on the spine, neck, and eyes during long seated work.
• Psychological needs: Work environment and conditions affect mental state. Comfortable, safe, and calm surroundings help reduce stress, improve focus, and boost creativity. Mental comfort significantly influences work quality and productivity.
• Social needs: Collaboration is common in work environments. Ergonomics supports healthy interpersonal relationships through solutions that promote cooperation and effective communication.

Numerous studies confirm that good ergonomic conditions increase work efficiency. For instance, employees with proper ergonomic solutions experience 20–30% less stress and fatigue compared to those in non-ergonomic environments—yielding both economic and social benefits.

Implementing Ergonomics in the Workplace

With the growth of computer technologies, ergonomics emphasizes healthy office conditions. Proper posture, furniture design, and workspace setup greatly reduce muscular tension and negative effects of unhealthy work habits.

Ergonomics in Transportation and Industry

In physical labor environments like transport and industry, ergonomics focuses on reducing physical burden, improving work time efficiency, and lowering injury risk. Vehicles and industrial equipment are redesigned to meet human physical and psychological needs.

Critical Areas: How Ergonomics Minimizes Injury Risk

In industrial settings, ergonomics examines movements, work heights, ideal postures, and weight considerations to reduce injury risk. Using ergonomic tools, workers can perform tasks without excessive physical strain.

Impact of Technological Innovations on Ergonomics

Advances in technology bring new opportunities for ergonomic applications. Modern computer programs and innovative devices enable environments tailored to human needs.

For example, high-tech chairs, desks, and interactive screens that self-adjust allow users to set their positions according to preferences, promoting health and reducing muscular strain—especially for those working seated all day.

Special software—like VR-based workstations—enables simulation and testing of ergonomic environments without real-world modifications, making prototype testing and refinement much easier.

Ergonomic Principles for Interfaces and Devices

In technology use, the human-device interaction is key. A primary goal of ergonomic design is to make interfaces intuitive and accessible for effective, frictionless use.

Effective ergonomic interfaces consider memory, attention, and perception characteristics:

• Clarity and simplicity: All actions and controls should be understandable and easy to access.
• Stepwise progression: Complex functions are broken into simple steps to reduce error chances.
• Comfortable reach: In some interfaces (like adjustable desks or mobile control panels), functions should be accessible without excessive movement.

Operational Memory and Attention Ergonomics

Optimizing attention and short-term memory is crucial in multitasking scenarios. Since working memory is limited, devices and software should be designed to reduce cognitive load.

Technological methods include:

• Prompts and alerts to notify users of errors,
• Information automation to progress or correct actions automatically,
• Color-coded systems—using colors for steps or actions to aid quick orientation.

Psychological Needs and Ergonomics

This section explores how ergonomics supports psychological wellbeing, particularly in reducing stress and enhancing focus.

How Ergonomics Reduces Stress

Work-related stress adversely affects quality and health. Ergonomics offers methods to lower stress—especially during prolonged, heavy tasks:

• Providing comfortable positions and environments tailored to physical needs helps workers feel more at ease,
• Designated transition areas—such as rest corners—offer short breaks to ease stress.

Ensuring Focus and Psychological Stability

Stable mental state is vital for concentration and efficiency. Ergonomic environments aim to reduce noise, offer proper lighting and interior design that promote calm.

When a worker has a quiet, balanced environment, it’s easier to focus without distraction. Proper placement of devices also helps minimize interruptions.

Emotional Ergonomics: Human–Machine Interaction

The relationship between people and technology can positively or negatively influence mood and performance. Emotional ergonomics aims to create environments where devices and tools are intuitive and user-friendly.

Applying Ergonomics in Healthcare
