Artificial Lighting and its Relation with Body Posture in Office Workplaces

Abstract

Background: Inadequate lighting in the workplace can cause unconventional changes in the posture of office workers. Poor ergonomic conditions in the office cause inappropriate postures during work and increase pressure on the musculoskeletal system which can cause some disorders in long-term. In this study, the relationship between work environment lighting with the prevalence and severity of musculoskeletal pain among office workers has been investigated.

The effect of housework, psychosocial stress and residential environment on musculoskeletal disorders for Chinese women

“…This indicated that most Chinese women in the survey sacrificed their own resting time to serve the family even after the paid work, which may further strengthen the effect of housework on MSDs. It was important to note that our study (−0.27) demonstrated the protective role of indoor environment satisfaction on MSDs in contrast to the risk role in the study (0.13) of Nagasawa et al Previous studies have shown indoor environmental stressors, such as temperature, humidity, noise and vibration, can cause musculoskeletal tension and increase the risk of MSDs ( Magnavita et al, 2011 ; Pienimaki, 2002 ; Pirmoradi et al, 2018 ; Telfer & Obradovich, 2017 ). In fact, indoor environmental satisfaction reflected individuals’ subjective judgement scales for indoor environment quality, and good indoor environmental quality can reduce the risk of MSDs.…”

“…Previous studies have found that physical stress contributed by workplace conditions, such as awkward postures, carrying loads, hand/arm vibration, wrist deviations and contact stress, can significantly affect the musculoskeletal system ( da Costa & Vieira, 2010 ; Punnett & Wegman, 2004 ; European Agency for Safety and Health at Work (EU-OSHA), 2010 ). Physical environment factors in the workplace, including low temperature ( Pienimaki, 2002 ), humidity ( Telfer & Obradovich, 2017 ), noise and vibration ( Magnavita et al, 2011 ) and poor lighting ( Pirmoradi et al, 2018 ), may directly or indirectly lead to physiological reactions that can potentially increase musculoskeletal load, which raise the risk of MSDs. Associations have also been found between MSDs and psychosocial (or organisational) stress results from high work demands, low social support, discrimination in the workplace, working long hours, lack of breaks, and low job satisfaction ( European Agency for Safety and Health at Work (EU-OSHA), 2021 ; Hauke et al, 2011 ; Lang et al, 2012 ).…”
