We investigated if beverage were a trigger for nostalgia resulting in psychological effects other than feelings that typically result from drinking a beverage. This study had a pre-post comparative design. Participants (N=487, age range 15–79 years) were instructed to make a beverage at home by themselves. We used a questionnaire to determine their mood before drinking the beverage, and their mood, perceived social support, and nostalgic emotions after drinking. Results indicated a decreased feeling of anxiety and loneliness after drinking, regardless of nostalgia. Moreover, participants who reported feeling nostalgic had a more positive and relaxed feelings as well as increased perceived social support from family and significant others, whereas this was not the case doe participants that did not feel nostalgic. Also, structural equation modeling indicated that nostalgia led to an increase in perceived social support via the increased positive mood. These findings suggest that the psychological effects of drinks are enhanced by nostalgia.
