Which condition is known to increase the risk of pressure injuries?

Restricted mobility is a significant factor that increases the risk of pressure injuries. This condition often affects individuals who are unable to change positions regularly, whether due to illness, injury, or age-related factors. When a person remains in one position for extended periods, particularly in areas where bones are close to the skin, such as the heels, hips, and tailbone, pressure can build up. This pressure reduces blood flow to the skin and underlying tissues, leading to tissue damage and ultimately resulting in pressure injuries, also known as bedsores or ulcers.

In contrast, high blood pressure does not have a direct relationship with the development of pressure injuries. Skin allergies may cause discomfort or irritation but do not typically lead to the conditions that create pressure injuries. Low body temperature can affect overall health but is not a primary factor linked to pressure injury development. Therefore, restricted mobility is the most critical condition among the options listed when it comes to increasing the risk of these injuries.
