In situations where work‐related musculoskeletal symptoms or disorders are prevalent, it may be advantageous to apply work breaks. It is generally assumed that work breaks may provide a recovery period for any musculoskeletal structure that is stressed during the working process. This review evaluates the effectiveness of different work‐break interventions for preventing work‐related musculoskeletal symptoms and disorders in healthy workers, when compared to conventional or alternate work‐break schedules. Associated Cochrane Clinical Answer: Do additional work breaks improve musculoskeletal symptoms and work performance?

The prevalence of musculoskeletal symptoms among sedentary workers is high. Interventions that promote occupational standing or walking have been found to reduce occupational sedentary time, but it is unclear whether these interventions ameliorate musculoskeletal symptoms in sedentary workers. This review investigates the effectiveness of workplace interventions to increase standing or walking for decreasing musculoskeletal symptoms in sedentary workers. Associated Cochrane Clinical Answer: Do workplace interventions to increase standing and/or walking improve musculoskeletal symptoms among sedentary office workers?

Many people are employed in sedentary occupations. Physical inactivity and excessive sitting at workplaces have been linked to increased risk of cardiovascular disease, obesity, and all‐cause mortality. This review evaluated the effectiveness of workplace interventions to reduce sitting at work compared to no intervention or alternative interventions. Associated Cochrane Clinical Answers: Compared with traditional sit desks, do sit‐stand desks reduce time spent sitting at work? and For office employees, what are the effects of counseling in the workplace on time spent sitting?

Exposure to light plays a crucial role in biological processes, influencing mood and alertness. Workers may be exposed to insufficient or inappropriate light during daytime, leading to mood disturbances and decreases in levels of alertness. This review assesses the effectiveness and safety of lighting interventions to improve alertness and mood in daytime workers. Associated Cochrane Clinical Answer: What is the impact of changing workplace lighting on alertness and mood of daytime workers?

Computer users may experience problems with vision and other eye functions, including eyestrain, eye ache, headache, double vision and blur, burning, irritation, ocular dryness, and tearing. This review examines the evidence on the effectiveness, safety, and applicability of optical correction of refractive error for reducing and preventing eye symptoms in computer users. Associated Cochrane Clinical Answer: For computer users, how do progressive computer glasses to correct refractive error compare with monofocal computer glasses for people with presbyopia?

Work‐related musculoskeletal disorders can involve the neck and upper limbs (shoulders, upper arms, elbows, forearms, wrists, and hands). This review assesses the effects of physical, cognitive and organizational ergonomic interventions, or combinations of those interventions, for the prevention of work‐related upper limb and neck musculoskeletal disorders among office workers. Associated Cochrane Clinical Answers: What are the effects of ergonomic equipment for prevention of musculoskeletal disorders of the upper limb and neck among office workers? and What are the effects of ergonomic training on musculoskeletal disorders of the upper limb and neck among office workers?
