Final answer:
Overexertion in the workplace can result from excessive physical efforts such as lifting heavy objects or repetitive motions without adequate rest, leading to injuries and disorders. Job strain can cause job burnout, with higher risk for older, unmarried manual laborers with unhealthy lifestyle factors. Historically, intense manual labor in industries like textiles posed severe physical dangers and inadequate safety measures led to debilitating conditions.
Step-by-step explanation:
Overexertion is caused by exerting excessive effort or force when performing tasks that can be physical or mental in nature. This occurs in situations such as lifting heavy objects, doing repetitive motions, or engaging in activities without proper rest or recovery time.
Overexertion can lead to a range of workplace injuries, including musculoskeletal disorders, muscle, tendon, or bone injuries which are common from inadequate recovery periods or inappropriate exercise techniques, such as lifting too much weight or not aligning joints properly during activities.
Furthermore, job strain is a significant contributor to job burnout, which can manifest in physical symptoms like muscle soreness and more severe conditions such as depressive disorders. Those at higher risk include older workers, unmarried individuals, and those in positions involving manual labor.
Factors such as heavy alcohol consumption, physical inactivity, overweight, and existing mental or physical health issues also correlate with higher incidences of job burnout.
The historical context adds that in certain industries like the textile factories, apart from the risk of fire, workers faced severe physical hazards leading to maiming or even death, which in some cases, were exacerbated by harsh punishments from overseers.
Extensive hours of labor-intensive work also resulted in an array of health issues, from back problems and swollen feet to hearing loss and respiratory issues due to poor workplace safety measures.
