Self-heating to warm the baby is the principle that iron absorbs oxygen in humid air to produce corrosion and heat release. The activated carbon in the mixture has strong adsorption, which can store water vapor in the air, liquefy it into water droplets, and react with iron powder in the air. Under the action of inorganic salt catalyst, iron hydroxide is generated and heat is released after rapid chemical reaction.
