Which of the following factors does NOT impede the healing process?

Healthy nutrition plays a crucial role in the healing process by providing the necessary vitamins, minerals, and energy needed for tissue repair and regeneration. Adequate nutrition supports various physiological functions, including immune response, collagen formation, and the overall maintenance of bodily functions, all of which are vital during recovery. When the body receives proper nutrients, it can effectively manage inflammation, repair damaged tissues, and restore injured areas to their optimal state more efficiently. Thus, healthy nutrition promotes healing rather than impedes it.

In contrast, separation of tissue, infection, and muscle spasm can hinder the healing process by causing additional trauma, prolonging recovery, or leading to complications that interfere with proper tissue repair.
