Which factor is least likely to contribute to impaired wound healing?

Regular physical activity plays a significant role in promoting overall health and enhancing the body's ability to heal wounds. Engaging in exercise improves circulation, increases oxygenation of tissues, and reduces the risk of complications associated with sedentary behavior. In fact, regular physical activity can help to strengthen the immune system, accelerate recovery, and contribute positively to tissue integrity.

On the other hand, chronic stress, smoking, and chronic diseases are all factors that can inhibit wound healing. Chronic stress can lead to hormonal changes that negatively affect the body’s healing response. Smoking introduces harmful substances into the body that can reduce blood flow and oxygen to tissues, impairing the healing process. Chronic diseases such as diabetes or cardiovascular conditions can also complicate wound healing by disrupting the normal physiological processes necessary for recovery. Thus, while the other choices contribute to impaired wound healing, regular physical activity is least likely to do so.
