We often hear the saying "drinking alcohol to keep warm," but it's more accurately "fake warmth from true fever."
True fever refers to the sensation of overall body warmth after drinking alcohol. This is because alcohol can stimulate the body's capillaries, causing them to dilate and blood circulation to increase. Blood continuously carries heat from the body's core to the surface, giving a flushed face and a warm feeling throughout the body. However, it's essential to note that this brief feverish feeling does not actually raise our core body temperature.
