We found low- quality evidence that different work-break frequencies may have no effect on participant-reported musculoskeletal pain , discomfort and fatigue .
For productivity and work performance , evidence was of very low- quality that different work-break frequencies may have a positive effect .
For different types of break , there may be no effect on participant-reported musculoskeletal pain , discomfort and fatigue according to low- quality evidence .
Furthermore , work-break interventions should be reconsidered , taking into account worker population s other than office workers , and taking into account the possibility of combining work-break intervention with other interventions such as ergonomic training or counselling , which may may possibly have an effect on musculoskeletal outcomes and work performance
BACKGROUND Work-related musculoskeletal disorders are a group of musculoskeletal disorders that comprise one of the most common disorders related to occupational sick leave worldwide .
Musculoskeletal disorders accounted for 21 % to 28 % of work absenteeism days in 2017/2018 in the Netherl and s , Germany and the UK .
There are several interventions that may be effective in tackling the high prevalence of work-related musculoskeletal disorders among workers , such as physical , cognitive and organisational interventions .
In this review , we will focus on work breaks as a measure of primary prevention , which are a type of organisational intervention .
OBJECTIVES To compare the effectiveness of different work-break schedules for preventing work-related musculoskeletal symptoms and disorders in healthy workers , when compared to conventional or alternate work-break schedules .
Post-lunch nap as a worksite intervention to promote alertness on the job
A worksite study was conducted to examine whether a 15-min nap during a post-lunch rest period would affect subsequent alertness , performance , and nocturnal sleep in eight factory workers under a 3-week protocol . Subjects were asked to take the nap at 12:30 h on a reclining chair during the nap week , and to remain awake during the no-nap week . The order of these 2 weeks was counterbalanced between the subjects . During the third , follow-up week , each subject determined whether or not she/he would nap . Alertness on the job and nocturnal sleep were assessed using a sleep diary .  Wrist activity was also recorded during sleep at night . Choice reaction time task ( RT ) was performed at 10:00 and 15:00 h every day of the nap week and every other day of the no-nap and follow-up weeks . Perceived alertness was significantly higher in the afternoon after nap than after no nap at the end of the week . Similar effects were observed during the follow-up week where almost half of the subjects napped . No significant differences between the three weeks were found for RT performance or nocturnal sleep . Workers ' attitudes toward the nap were favourable . Although further intervention research is required , our results suggest that post-lunch napping may have the potential to promote daytime alertness at work
