Was "Drinking alcohol will warm you up in cold weather" taught in school?

Yes — and not as a joke question on a quiz. This health claim showed up in textbooks, worksheets, and classroom posters through the 1980s, which is why so many people still remember it as settled fact long after the science moved on.

When was this understanding updated?

The evidence had largely shifted by around 1985. Schools don't flip overnight, though — plenty of classrooms kept teaching the older version for years after researchers had already moved on.

Is "Drinking alcohol will warm you up in cold weather" true?

A drink before heading into the cold is old enough to feel like folk wisdom, and it does make you feel warmer almost instantly, which is exactly the trap. That warmth comes from blood vessels near your skin dilating, which speeds up heat loss from your core rather than preserving it. The feeling and the physiology point in opposite directions, and that mismatch is precisely what raises hypothermia risk on a genuinely cold night out.

What you were taught

Drinking alcohol will warm you up in cold weather

What we know now

Alcohol can make your skin feel warm by dilating blood vessels near the surface, but it increases heat loss and can lower core body temperature. It can raise hypothermia risk even when it feels comforting.

Updated understanding emerged around 1985
