A lot can be said for nostalgia’s benefits. In a 2012 study published in the journal Memory, Routledge and his colleagues showed that nostalgizing helps people relate their past experiences to their present lives in order to make greater meaning of it all. The result can boost their mood and reduce stress. "Nostalgia increases feelings of social connectedness to others," he says. "Nostalgia makes people feel loved and valued and increases perceptions of social support when people are lonely."
