A clear system for choosing heat, cold, and contrast therapy.

Cold therapy uses cooling to change tissue temperature and is commonly used in acute or post-activity contexts. Heat therapy uses warmth to change tissue temperature and is commonly used for stiffness, comfort, and movement preparation. Contrast therapy alternates both in timed sequences for recovery and conditioning contexts. This site is an educational reference that explains the modalities and decision factors without prescribing protocols.

How the topics connect

Cold therapy and heat therapy are the two foundational thermal modalities. Each produces distinct physiological effects: cold reduces blood flow and inflammation; heat increases blood flow and relaxes tissue.

Heat vs cold therapy provides the decision logic for choosing between them based on condition type (acute vs chronic), timing (injury phase), and goals (pain relief vs recovery).

Contrast therapy combines both modalities in timed sequences. It is used for recovery, circulation enhancement, and adaptation training.

Contrast therapy setups covers the practical equipment and configurations needed to implement contrast protocols at home or in facilities.
