Nostalgia Reframes Itself: New Study Shows Fond Memories Grow More Bittersweet Over Time, with Thai Perspective
A new study challenges the idea that nostalgia is purely comforting. Researchers report that memories once cherished for their warmth can become increasingly bittersweet as years pass. Published in Cognition & Emotion, the work explores how the emotional tone of past events shifts over time and what this means for Thai readers who deeply value family, festivals, and collective memory.
Nostalgia has long been linked to positive outcomes—strengthening social bonds, supporting identity, and sustaining optimism. The latest research, led by Tim Wildschut and colleagues, reveals a more complex picture: repeated reflection on the past often carries a subtle undertone of sadness, and this duality grows with time.
