People seem to experience fewer hangovers less often as they get older, and this isn’t just because older people drink less with age.
Furthermore, the severity of hangovers seems to decline with age, regardless of the amount of alcohol consumed or BAC. Older adults also seem to experience lower subjective intoxication. The reasons why aging is associated with a lower frequency and severity of hangover haven’t been investigated, but some research suggests that older adults may have a lower pain sensitivity, which could result in their reporting a lower hangover symptom severity.[1] Additional reasons why older adults may experience less-severe hangovers may include a longer drinking experience or greater alcohol tolerance, the preference of older adults to drink pricier liquors that contain fewer congeners and toxins, or differences in neurological development and alcohol metabolism.[2]
