Scientists share theories on why some people are 'alcohol resistant' and never get hangovers

Some people never get hangovers — and science suggests their genes may be running a faster metabolic program the rest of us simply don't have access to.

Theory Briefing
- Certain individuals appear 'alcohol resistant,' metabolizing booze faster due to genetic variants that clear toxic acetaldehyde more efficiently.
- Scientists link hangover immunity to genetic differences in alcohol dehydrogenase enzymes, a textbook case of how heredity shapes physiology.
- The research challenges the assumption that hangovers are a universal biological punishment, suggesting individual variation is far greater than thought.
