What is the purpose of applying heat therapy?

The primary purpose of applying heat therapy is to increase blood flow to a specific area of the body. When heat is applied, it causes blood vessels to dilate, improving circulation, which can promote healing and aid in the recovery process. Enhanced blood flow delivers more oxygen and nutrients to the affected tissues while also facilitating the removal of metabolic waste products. This increased circulation can help relax and soothe tight muscles as well, contributing to pain relief and a reduction in muscle stiffness.

While heat therapy can have several benefits including promoting tissue regeneration and potentially aiding in issues related to swelling, the most direct and fundamental action is its ability to enhance blood flow, which is crucial for effective healing and recovery.
