Cold Sprays and Pain Relieving Gels
Cold Sprays and pain relieving Gels are classified as topical analgesics (Pain Relieving), which work through a ‘counter irritant’ mechanism. This means that the active ingredient creates a sensation that overrides pain signals to the brain. This process is known as ‘Gate Control Theory’, where nerve impulses from one stimulus block the nerves containing pain signals to the brain. Some products may also stimulate cold receptors in the skin that may help regulate pain as well.
