Impact of mental resilience and perceived immune functioning on the severity of alcohol hangover.

Students consumed a mean (SD) of 12.3 (5.9) alcoholic drinks the evening before their latest hangover. A significant positive association was found between mental resilience and perceived immune functioning (r = 0.372, p = 0.000). No significant associations of hangover severity were found with mental resilience (r = - 0.010, p = 0.858), or perceived immune functioning (r = - 0.025, p = 0.645). Previous research revealed that hangover resistant and hangover sensitive drinkers report having significantly different levels of immune functioning, and that the immune system is involved in the development of alcohol hangover. These findings suggest that levels of mental resilience and perceived immune functioning are not related to the severity of hangovers in hangover sensitive drinkers.
