This winter break, as I sit in my childhood bedroom, where I once filmed silly YouTube videos, tried my hand at DIYs, poured over textbooks for board exams, and went through the entire university application process, a wave of nostalgia crashes over me. It’s strange to think I’ll never be that child again: the one who would be begrudgingly dragged out of her bed for school but found joy in the little moments, daydreaming about adulthood, and believing there was so much time ahead. Nostalgia has a way of creeping up on you, it’s not just about missing the past; it’s about the warmth of revisiting those moments in your mind. Sitting here now, I realize how much my childhood has shaped me, how the sound of laughing with friends, the scribbles in my notebooks, and even my father’s screams to wake me up early in the morning are now fragments of a life I can only revisit in my memory. Nostalgia reminds me of who I was, offering a bittersweet comfort in how far I’ve come. Defining Nostalgia In the 17th century, Swiss physician Johannes Hofer coined the term “nostalgia” to describe the longing soldiers felt to return home, considering it a cerebral disease (Beck, 2013). Today, nostalgia is seen as a source of comfort, allowing us to reflect on cherished moments like our childhood. These memories often resurface during challenging times, offering reassurance and emotional stability (Wang et al., 2024). Nostalgia wasn’t always viewed positively. Professor David Gerber from Buffalo University highlights that society has only recently begun to see nostalgia as beneficial. He explains that even painful memories, when approached constructively, can help individuals navigate the massive changes that challenge their identities (Kidwell, 2019). Psychologist Erica Hepper from the University of Surrey notes that nostalgia is particularly common among young adults. Since they experience significant transitions, such as leaving home or starting a new job, nostalgia helps them cope by providing a sense of stability (Austin, 2022). It allows them to draw strength from fond memories, countering feelings of anxiety, loneliness, or depression. How the Brain Processes Nostalgic Memories At the heart of nostalgia are three key brain regions that play vital roles in processing memories and emotions: The Hippocampus: Responsible for memory formation and recall, the hippocampus is essential for retrieving autobiographical memories (Wiltgen et al., 2010). When we experience nostalgia, the hippocampus plays a crucial role in retrieving self-referential memories—personal experiences tied to our sense of identity—which, when recalled, often evoke vivid details and strong emotional connections. The Amygdala: This region is central to emotional processing. It attaches emotional significance to memories, which explains why nostalgic experiences are often tied to feelings of warmth, joy, or longing (Professional, 2024). The Prefrontal Cortex: The medial prefrontal cortex (mPFC) plays a crucial role in self-reflective thinking. When we experience nostalgia, the mPFC helps us contextualize past memories within our current sense of self, enabling us to reflect on how our experiences have shaped who we are today (Yang et al., 2022). Sensory Cues One of the strongest sensory triggers for nostalgia is smell, a connection that has been extensively studied by cognitive neurobiologist Howard Eichenbaum. Their research demonstrated that odours interact directly with the limbic system, particularly the hippocampus, where memories are formed and retrieved, and the amygdala, which processes emotional significance. Unlike other sensory inputs, which must first pass through the brain's thalamus, olfactory signals have a direct pathway to these regions, making scent a uniquely potent trigger for vivid, emotionally rich recollections (Holohan, 2012). Scents like baked goods and other cooking aromas are especially potent in triggering nostalgic memories (BBC, 2014). This link between scent and memory is just one example of how different sensory cues shape nostalgia. Music, for instance, is another powerful trigger, often reviving memories with striking emotional clarity. Like scent, music engages the limbic system, particularly the hippocampus and amygdala, reinforcing the idea that nostalgia is deeply intertwined with the brain’s emotional and memory-processing mechanisms. Interestingly, a study by Cornell University and UC Santa Cruz found that nostalgia for music extends beyond personal experiences. College-aged participants reported feeling nostalgic for songs from their parents’ youth, such as those from the 1960s and 1980s, likely because these songs were frequently played during formative years (Beck, 2013). This is can also be linked to known as anemoia, the feeling of nostalgia for a time one has never personally experienced. Traditionally, nostalgia has been understood as a longing for one’s own past experiences, but philosopher Felipe De Brigard challenges this view by emphasizing the role of imagination in memory reconstruction. He argues that nostalgia can also stem from idealized portrayals of the past, shaped by cultural narratives and historical storytelling (Jarrett, 2023). Shows like Bridgerton or Bollywood films set in pre-independence India can evoke a sense of longing for a time one has never lived in, making one feel like they were “born in the wrong era” despite the portrayals being highly selective. They present a rose-tinted version of history, glossing over systemic inequalities, rigid social hierarchies, and the struggles of marginalized communities. Why We Crave Nostalgia In 2025, cultural trends seem to be looping back to the past, with everything from movies and music to fashion trends. Blockbuster films like Barbie and Fashion Trends like Y2K dominate the digital landscape, raising a central question: Have we truly run out of new ideas, or is there a deeper desire to revisit the moments, people, and things we know and love? Nostalgia as a Reflection of Self Psychologist Krystine Batcho explains that nostalgia helps us reconnect with past versions of ourselves, offering stability in an ever-changing world. (Does Nostalgia Have a Psychological Purpose? With Krystine Batcho, PhD, n.d.) Revisiting familiar media and experiences reinforces our identity, reminding us of where we’ve come from and how we’ve grown. It provides a sense of continuity, making us feel grounded when the present feels uncertain. Nostalgia as a Coping Mechanism In times of crisis, nostalgia provides refuge and a sense of control. The COVID-19 pandemic, with its isolation and uncertainty, fueled a surge in nostalgic media as people turned to familiar stories, music, and cultural symbols for reassurance. Nostalgia can help ease feelings of loneliness by connecting us to shared memories and experiences. When the present feels overwhelming, looking back at times that felt simpler and more stable can be a powerful way to process emotions and regain perspective (Gharat, 2024). Nostalgia in Troubling Times More than just escapism, nostalgia helps us make sense of our past, even reframing difficult experiences. As time passes, the emotional intensity of past struggles fades, allowing us to see them as part of our personal growth rather than just sources of pain (Davis, 2019). Nostalgia also reinforces resilience—by remembering how we’ve navigated challenges before, we gain confidence in our ability to overcome present and future difficulties. Ultimately, nostalgia serves several important psychological functions: it offers a tool for self-reflection, provides a coping mechanism for managing current challenges, and reinforces our sense of continuity and control. By revisiting past experiences, whether they were happy or difficult, we are reminded of how far we’ve come and of the resilience that defines us. In uncertain times, nostalgia provides both comfort and hope, helping us process the present while reinforcing the belief that things will improve again, just as they have in the past.
