Considerations on physical and cognitive ergonomics in the workplace

Abstract

Introduction: Physical and cognitive ergonomic considerations in the workplace are essential to ensure the well-being and productivity of employees. Physical ergonomics focuses on adapting work spaces and tools to the body's needs, while cognitive ergonomics addresses the mental load associated with tasks. Together, they promote a healthy and efficient work environment. Objective: Describe the considerations about physical and cognitive ergonomics in the workplace. Materials and Methods: This research was based on a documentary review of the collection, analysis and synthesis of information from secondary sources, such as books, scientific articles, technical reports and other relevant documents. Results: Among some anatomical-functional principles: Keep everything within reach, Use person/work equipment relationship based on elbow height as a reference, The way of holding reduces effort, Correct position between posture/position, for each task, Movements Repetitive tasks are excessive, Minimize physical workload, Minimize Direct Pressure, Adjust and change posture, Maintain a comfortable environment in the workplace, Highlight clearly to improve compression, Organization of work. Conclusions: Given the multiplicity of factors to be evaluated in ergonomics, there are many models and methods that can be used and it is practically impossible to find a method that includes all the factors. One of the classifications that can be used is one that distinguishes two large groups, objective methods and subjective methods.
