According to Dr. Juliana Brienes, nostalgia has some pretty amazing effects that leave us wanting more. Firstly, nostalgia tends to keep us feeling as happy as can be. Studies have actually found that when nostalgia is triggered in participants (by having them do something like write down a nostalgic event), they tend to feel positive emotions. This can be enhanced by focusing on all the things we’ve gained in the past (like Harry Potter movies), rather than thinking about all that we’ve lost (like Harry Potter characters).
