Why does mustard make you sweat?

Mustard can make you sweat due to its ingredients, particularly compounds like allyl isothiocyanate, which can stimulate the body's heat receptors. When consumed, these compounds can increase your metabolic rate and induce a sensation of warmth, prompting sweating as a natural cooling response. Additionally, the spiciness of mustard can trigger the body's thermoregulation mechanisms, leading to increased perspiration.
