A change in temperature can indicate a potential deep tissue injury breakdown due to its association with underlying tissue changes. When deep tissue injuries occur, the body's response often involves inflammation, which can lead to localized increases in temperature as blood flow increases to the affected area. This temperature change may be a sign of tissue damage, indicating that the skin or underlying structures are not receiving adequate blood supply or that there is damage due to pressure.

In contrast, an increase in appetite is not generally indicative of deep tissue injury; it's more related to overall health and recovery. Bright white discoloration often suggests a different type of skin change such as ischemia or necrosis. Improved skin turgor reflects hydration and good elasticity, which do not suggest the presence of a deep tissue injury. Therefore, the assessment of temperature changes is critical for early detection and management of potential deep tissue injuries.
