Cold therapy – or “cryotherapy” – is the practice of applying something cold to the source of pain. For years, cold therapy has been used to reduce pain, swelling and nerve activity using ice, cold packs, and ice baths. Now, topical cold therapy pain relievers like Biofreeze offer additional benefits.
When Biofreeze is applied, menthol binds with temperature-sensitive receptors in the skin. Activating these receptors is thought to modulate pain signals through the body’s natural pain relieving systems. This mechanism works similarly to ice, but with additional benefits.
