Genetic Influence on Hangovers


Some people get hangovers after a night of drinking, while others don’t, and the reason may be in their genes, a new study in Australia suggests.


Researchers looked for links between the study participants’ genetic makeups and the number of hangovers the individuals reported experiencing in the past year.

Results:

Genetic factors accounted for 45% of the difference in hangover frequency in women and 40% in men.

In other words, genetics accounts for nearly half of the reason why one person experiences a hangover and another person doesn’t, after drinking the same amount of alcohol, the study said. The other half probably comes from outside influences unrelated to DNA, such as how quickly a person drinks, whether they eat while they drink and their tolerance for alcohol.
