Abstract
This study conducted a non-interventional longitudinal study to collect physiological data from tunnel construction workers using an Internet-of-Things-based photoplethysmography physiological monitoring system. The analysis results indicated that among tunnel workers, the SDNN and RMSSD of muck car drivers were significantly lower than those of other occupations, reflecting decreased sympathetic innervation or parasympathetic activity, which is typical of mental stress. During tunnel construction, many HRV indicators of workers were significantly higher in the morning and afternoon than during the lunch break. The most obvious physiological response to noise was observed in the muck car driver, where the SDNN, LF, and LF/HF indices increased significantly under noise >85dB. This study fills an empirical gap in the objective assessment of mental stress among tunnel workers, providing a reference for optimising work scheduling and task allocation. It provides a framework for occupational health monitoring and stress management strategies.
期刊介绍：
Ergonomics, also known as human factors, is the scientific discipline that seeks to understand and improve human interactions with products, equipment, environments and systems. Drawing upon human biology, psychology, engineering and design, Ergonomics aims to develop and apply knowledge and techniques to optimise system performance, whilst protecting the health, safety and well-being of individuals involved. The attention of ergonomics extends across work, leisure and other aspects of our daily lives.
The journal Ergonomics is an international refereed publication, with a 60 year tradition of disseminating high quality research. Original submissions, both theoretical and applied, are invited from across the subject, including physical, cognitive, organisational and environmental ergonomics. Papers reporting the findings of research from cognate disciplines are also welcome, where these contribute to understanding equipment, tasks, jobs, systems and environments and the corresponding needs, abilities and limitations of people.
All published research articles in this journal have undergone rigorous peer review, based on initial editor screening and anonymous refereeing by independent expert referees.
