What physiological functions can compression or contact stress interfere with?

• A. Digestive and respiratory functions
• B. Circulation and nerve function
• C. Muscle development and flexibility
• D. Bone density and mass

Answer: (B)

Compression or contact stress primarily impacts circulation and nerve function. When parts of the body are subjected to excessive pressure, the blood flow to those areas can be reduced. This diminished circulation can lead to several issues, such as numbness, tingling, or a feeling of weakness as the nerves responsible for sensation and muscle control are affected. Additionally, sustained pressure on nerves can result in more severe conditions such as carpal tunnel syndrome or sciatica, demonstrating the importance of understanding and mitigating risks associated with ergonomic practices. While other physiological functions like digestive and respiratory functions can be affected by poor ergonomics in a broader sense (particularly in how posture can influence them), the primary concern regarding compression and contact stress is its more direct and immediate effect on circulation and nerve function. This highlights why addressing such stresses in the workplace is crucial for maintaining overall health and preventing injury.
