Ahhh, the good old days! Memories of a better time or a happier version of ourselves can be sparked by a seemingly insignificant sight or smell or even an ordinary drive down a tree-lined road on a random Tuesday. But, beware... nostalgia is a powerful and deceptive force.
Some nostalgic memories are easy to explain. The smell of freshly cut grass will take me right back to my single-digit years. In my mind's eye, I can see Poppy in his overalls and newsboy cap riding the John Deere as my sisters and I played restaurant in the shed. Others are a bit more mysterious - like seeing the movie The Breakfast Club makes me instantly remember a high school crush. I don’t know why… I remember little about this boy mostly because I don’t think he ever even spoke to me. Why that particular movie brings him back to mind is a mystery to me.
The definition of nostalgia has changed over time. The etymology of the word is based on two word parts meaning "homecoming" and "pain." The Greek word nostos means “to return” and algos means “suffering.” Nostalgia was originally described as a “neurological disease of essentially demonic cause” by Johannes Hoffer, the Swiss doctor who coined the term in 1688. For centuries, nostalgia was considered a debilitating and potentially fatal medical condition expressing "extreme homesickness."
Today, we think of nostalgia as a wistful yearning for days gone by. But neuroscience tells us that nostalgia is more than a pleasant trip down memory lane. Memory is important to survival. We could not carry out the basic functions of living without the powers of recall. Learning would be impossible and nothing would have meaning. But, not all memories are created equally.
Short-term memories contain information such as where you parked the car or the name of the new oyster bar everyone is talking about. These memories are stored in the frontal lobe. But long-term memories — such as the name of your childhood friend or every word of Bohemian Rhapsody — are moved via neurotransmitters (through a process called “consolidation” that often happens during sleep) to the limbic system.
Researchers have used brain imaging technology to discover that when nostalgia is felt, dopamine is produced and deposited directly into the hippocampus - the part of the brain responsible for learning, emotions and memories. That shot of dopamine results in a host of positive mental states and behaviors such as improved mood, increased social connectedness, and a more optimistic outlook on life.
Studies also show that after experiencing a nostalgic episode people are more generous, tolerant, and altruistic. One reason for this is that nostalgic stories often include some kind of problem or hurdle to overcome. They are etched in our memories when the outcome is positive - especially when the positive outcome is the result of another person's kindness. This makes us feel connected and protected.
Other studies show that nostalgia can heighten creativity. Because nostalgia often evokes a greater sense of belonging, meaning, and security, we are more open to imagining future experiences and more open-minded about present experiences which ultimately encourages creativity.
That’s the seductive part.
Here’s the liar part.
Most of our nostalgic experiences are idealized versions of the way we want it to be, not necessarily reality. Psychoanalysts call this a screen memory - not a true recreation of the past, but a patchwork of positive and powerful emotions stitched together with all of the negative emotions filtered out.
Since it is a natural bias is to remember the good without any of the pain or hurt that may have also been part of the event, some scientists regard nostalgia as an emotional state rather than a recall of memories. In a sense, nostalgia tricks the brain into creating so that we can “relive" the best version of our memories.
Nostalgia is a luminary who fixes all the potholes on memory lane, plants blooming trees on either side, and delivers sunshine, blue skies and hot little convertible for the ride.
In addition, when we are under stress or feeling lonely, we may be wired to automatically and unconsciously reach for nostalgia. Were you more nostalgic during the isolation of the pandemic? That social isolation made many of us feel lonely, and those feelings of nostalgia were the result of our limbic systems hard at work trying to evoke memories of happier times when we felt more connected.
So, the next time you are feeling nostalgic, take that trip back in time with the satisfaction that you’re likely to reap positive mental benefits from the experience. However, before you start lamenting about how life was so much simpler, easier, better, or happier back then, keep in mind that what you remember is likely to be far better than what actually happened.
Wouldn't it be great to know you're living the good old days
before you leave them?
It's so easy to vacation in yesterday and dream about tomorrow. The thing is... what you did yesterday is how you got where you are today. What you do today determines where you'll be tomorrow.
Here. This. Now. Be present.
