What factor related to moisture can contribute to pressure injuries?

Excessive humidity can contribute to pressure injuries because it creates an environment that increases moisture levels on the skin. When skin becomes overly moist, it can lead to maceration, which breaks down the skin's protective barrier and makes it more susceptible to injury. This compromised skin can easily be damaged by pressure, friction, or shear forces, which are critical factors in the development of pressure injuries.

Moreover, excessive moisture can also lead to skin conditions such as dermatitis or fungal infections, further impairing the skin's integrity. Therefore, maintaining a balance of moisture is important in preventing pressure injuries, and managing humidity levels is a crucial part of skin care for individuals at risk.
