How does chronic stress affect wound healing?

• A. It impairs immune function and delays tissue repair
• B. It accelerates immune response and speeds repair
• C. It has no effect on healing
• D. It reduces scarring

Answer: (A)

Chronic stress keeps the body in a prolonged state of alert, with elevated cortisol and stress hormones circulating over time. This hormonal pattern suppresses immune system activity and disrupts the inflammatory and proliferative stages that are essential for wound healing. When immune cells function is dampened, there’s less effective debris clearance and a higher risk of infection, which can stall the healing process. At the same time, cortisol and related factors can slow collagen synthesis and fibroblast activity, reducing new tissue formation, angiogenesis, and wound strength. The overall effect is slower wound closure and delayed tissue repair, with a greater chance of complications, especially if stress continues unabated. In practice, addressing chronic stress through psychosocial support, adequate sleep, nutrition, and mitigation of anxiety can help support better healing alongside direct wound care.
