“Alcohol warms you up.”

The idea that a drink can warm you up has been around for a long time, perhaps famously illustrated by images of St. Bernard rescue dogs carrying small barrels of brandy for lost travelers in the Alps. This common misconception stems from the immediate and noticeable feeling of warmth that spreads through the body shortly after consuming alcohol. People often interpret this sensation as their internal temperature rising, leading to the belief that alcohol is an effective way to combat the cold.

However, this feeling of warmth is a misleading physiological illusion. When alcohol enters the bloodstream, it causes a process called vasodilation, where blood vessels near the skin's surface widen. This increased blood flow to the skin makes the surface feel warmer and can even cause a flushed appearance. While your skin may indeed feel hot to the touch, this outward rush of blood actually draws heat away from your body's vital core, where organs need to maintain a stable temperature. As a result, your internal body temperature, which is crucial for health, begins to drop.

The danger of this "false warmth" is significant, particularly in cold conditions. Not only does alcohol actively lower your core body temperature, but it also impairs the brain's ability to regulate temperature and dulls your perception of how cold you truly are. This diminished awareness means you might not recognize the signs of dangerous heat loss, increasing your risk of hypothermia. The initial comforting sensation, combined with impaired judgment, makes it easy for people to continue believing in this harmful myth despite the scientific evidence to the contrary.
