Final answer:
Poor ergonomics can cause physical problems like back and neck pain, repetitive strain injuries, and injuries from mechanized labor, as well as psychological issues like stress from a poor work environment.
Step-by-step explanation:
Issues from Poor Ergonomics: Poor ergonomics can lead to various health problems due to inadequate workspaces and repetitive movements. One of the critical issues arising from poor ergonomics is back strain and pain. For instance, a person with bad posture at a desk may experience a significant torque around the hips, which the lower back muscles must counteract, requiring those muscles to exert large forces due to their small mechanical advantages. This can result in muscle strain and is a common problem for those using computers.
In addition to back pain, workers may suffer from neck pain by spending hours looking down at devices, leading to muscle injuries. The repetitive nature of tasks like typing can lead to repetitive strain injuries (RSIs), such as carpal tunnel syndrome, affecting the carpals, radius, ulna, and other bones of the hand and arm. Poor ergonomic conditions can also exacerbate conditions, like in textile factories where constant standing, exposure to heat, and inhalation of fibers cause swelling, miscarriages, respiratory problems, and heat exhaustion.
Other physical issues include injuries from mechanized labor, such as lost fingers and hands due to moving machine parts, as well as hearing loss from constant noise.
The psychological impact should not be underestimated. Little positive feedback, unsafe work conditions, bureaucratic frustrations, excessive paperwork, a sense of personal responsibility for clients, and work overload contribute to a stressful work environment. These psychological issues, combined with physical strain, can lead to a broad spectrum of health problems for workers, potentially resulting in long-term disabilities.
