“Drinking alcohol keeps you warm in cold weather.”

Many people mistakenly believe that a shot of liquor can ward off the chill of cold weather, a persistent myth often attributed to the immediate, deceptive feeling of warmth it provides. This misconception has even been perpetuated by popular imagery, such as the famous St. Bernard dogs depicted with small barrels of brandy around their necks, supposedly to revive stranded alpine travelers. This visual, though charming, has unfortunately reinforced a dangerous belief that alcohol offers genuine protection against the cold.

Scientifically, alcohol causes vasodilation, meaning it makes blood vessels near the skin's surface widen. This increased blood flow to the extremities, like the face and hands, creates a flushed, warm sensation. However, this is a superficial effect. Crucially, this process draws heat away from the body's core, where vital internal organs need to maintain a stable temperature. While you might feel warmer on your skin, your core body temperature is actually dropping.

The reason this myth endures is primarily due to that initial, misleading feeling of warmth. The body's sensory receptors interpret the increased blood flow to the skin as a sign of warming, leading individuals to believe they are getting warmer when, in fact, they are losing essential body heat more rapidly. This can be particularly dangerous in cold environments, as it increases the risk of hypothermia by impairing the body's natural ability to regulate its temperature and making a person less aware of the true extent of their cold exposure.
