#Debunking# Rumor Headline: Self-heating underwear is false propaganda

Rumor content: energy conservation, underwear without external energy input is impossible to produce heat by itself, "self-heating" is a fake advertisement.

Truth interpretation: "self-heating" is not false propaganda, because self-heating clothing uses heat-generating fiber materials that can produce heat with the help of external conditions, such as moisture-absorbing heat-generating fibers commonly used in daily clothing. There are more hydrophilic groups in this fiber structure that bind to water molecules to release heat, and the kinetic energy of water molecules is also converted into heat. Clothes containing such fibers are worn on the body by people, which can absorb the water vapor emitted by the human body to release heat and make people feel warmer. However, after "sucking up" moisture, the exothermic reaction will slow down, and the moisture will also be discharged, which will absorb the heat of the wearer. If the moisture is not drained in time, the fibers that "absorb" the moisture will bring discomfort to the wearer.

Reasons for the list: Common exaggerated publicity makes the public distrust of advertising, but the rumor information completely negates the "self-heating" function of clothing, and the discrepancy with the facts will also have a negative impact on the production and sales of enterprises.
