3. Looking at pictures of the trip evokes the same response as the vacation
"In his study 'Vacationers Happier, But Most Not Happier after a Vacation,' published in the Journal Applied Research in Quality of Life, Jeroen Nawijn, Ph.D., found that vacation length does not affect post-vacation happiness, and confirmed previous findings that a vacation's positive effects are short-lived.
However, we can prolong our getaways' positive effects by looking at photos, telling friends about the trip, and otherwise keeping vacation memories alive," says Heisz.
