Which factor listed can impair skin integrity?

Moisture can significantly impair skin integrity, particularly when it leads to conditions like maceration. Maceration occurs when the skin is exposed to excessive moisture, causing it to soften and break down, making it more susceptible to injury and infection. This is especially relevant in areas where skin is frequently in contact with moisture, such as in patients who are bedridden or those with incontinence.

While other factors like exercise, sunlight exposure, and hydration can also impact skin health, they typically do so in less direct ways. For instance, regular exercise generally promotes good circulation and overall health, which is beneficial for skin integrity. Sunlight exposure, while it can damage skin if excessive, is also essential for Vitamin D synthesis, which is vital for skin health. Hydration supports skin elasticity and resilience; therefore, it is crucial for maintaining normal skin function. However, none of these factors impairs skin integrity in the same direct and damaging way that excessive moisture can.
