Why is an aquathermia pad not placed under a body part?

An aquathermia pad is designed to deliver regulated heat to a specific area of the body to relieve pain and promote healing. When positioned directly under a body part, the heat generated by the pad cannot properly dissipate. This can increase the risk of overheating and potentially cause skin burns or damage due to excessive heat retention. The design of aquathermia pads often includes features that allow for heat to flow away from the pad and into the tissue, but if the pad is placed underneath a body part, the trapped heat can lead to complications.

In this context, the characteristics and intended use of the pad highlight the importance of proper placement to ensure effective therapeutic outcomes and patient safety. Other considerations such as discomfort from hoses, visibility of application sites, and alignment, while relevant in different contexts, do not fundamentally address the key issue of heat retention that arises when an aquathermia pad is placed underneath a body part.
