Mary has two 15-minute breaks during her workday. What is the primary purpose of these breaks?

The primary purpose of the breaks is to reduce physical strain and refresh focus. Breaks are essential in maintaining employee health and productivity, particularly in environments that may induce fatigue or repetitive stress. By taking short breaks, workers can alleviate muscle tension, reduce eye strain, and have a moment to recover mentally, which ultimately helps sustain their performance throughout the workday. These intervals provide an opportunity to step away from tasks that may cause physical discomfort and to return to work feeling renewed and more attentive. This practice aligns with ergonomic principles, which emphasize the importance of managing fatigue and maintaining comfort in the workplace.
