Wondering how small adhesive patches can provide hours of soothing heat? The warming mechanism relies on a simple chemical reaction.
Body warmer patches contain a mixture of iron, water, salt, activated charcoal and wood pulp inside the adhesive packaging. When exposed to oxygen as the package is opened, the iron is oxidized in an exothermic reaction.
This oxidation generates a controlled, sustained warming up to 130°F that is safely maintained by the other ingredients. The heat is gradually released into the skin surface, providing a soothing effect that lasts 5-24 hours depending on the formula.
The patches are designed to be thin to allow effective heat transfer while still protecting the skin from direct contact with the warming ingredients. Added components like jasmine and menthol provide aromatic and soothing properties.
Through this efficient chemical reaction, body warmer patches leverage technology to conveniently provide an instant warming effect without electricity, flame or mess. The patches are ultra thin and flexible to be worn comfortably under clothing on the go. Just open, adhere and enjoy the gentle heat.
