Does caffeine cause excessive body heat?

Caffeine can increase metabolic rate and stimulate the central nervous system, which may lead to a temporary increase in body temperature. However, this effect is typically mild and varies from person to person. In moderate amounts, caffeine is generally safe and does not cause excessive body heat in most individuals. It's important to stay hydrated, as caffeine can have a diuretic effect, which might contribute to feelings of overheating.
