Nostalgia triggers a reward pathway in our brains, according to science
Nostalgia is also proven to decrease loneliness and increase resiliency.
- Nostalgia is defined as a sentimentality for the past and can be unique to each person.
- Studies have shown that nostalgia can be used to combat loneliness and improve resilience. It can also be used to boost creativity.
- There is a kind of cooperative activity between memory and reward systems in your brain that plays a very specific role in how we experience nostalgia.
Nostalgia was originally thought of as a mental condition or disease, but is now known as a relatively positive emotion.

Nostalgia is a sentimentality for the past that is unique to each person, as it can be for a specific period in your life that you have positive associations with or it can be simply about the past in general.
Historically, nostalgia was thought of as a mental condition and had negative connotations to it. The term was originally coined in 1688 by Swiss medical student Johannes Hofer. The Greek words nostos (meaning homecoming) and algos (meaning pain or ache) gave meaning to the word we now know.
Nostalgia was originally thought of as a disease.
Something similar to nostalgia was described during the Thirty Years War when several soldiers were discharged from the Spanish Army of Flanders with "el mal de corazón," which was actually deemed a disease that became heavily associated with soldiers who became vulnerable to attack when they heard a certain Swiss milking song (called Khue-Reyen).
Modern-day nostalgia is considered to be a relatively positive emotion. Some examples of nostalgia include:
- Hearing a song on the radio that reminds you of a specific time, most likely the year that song was released.
- Finding an old high school yearbook in the attic while cleaning and remembering all the people you knew when you were a teenager.
- Eating a particular food that reminds you of a special place you once lived or visited.
Dr. Neel Burton explains it like this: "[Nostalgia is] a vehicle for traveling beyond the suffocating confines of time and space."
How nostalgia impacts the brain
Nostalgia counteracts loneliness, increases our resilience and boosts creativity levels, according to research.

Nostalgia is thought to play a critical role in physiological resilience. According to a 2015 study, neuroimaging has shown the involvement of the memory and reward pathways in the brain when we experience nostalgia. In this particular study, fMRI images of healthy females were used to investigate (and eventually prove) the direct link between memory-reward co-activation and nostalgia using childhood-related visual stimuli.
The nostalgia-related activity was shown in both memory and reward-systems, including the hippocampus, substantia nigra/ventral tegmental area (SN/VTA) and ventral striatum (VS). What this means is that there is a kind of cooperative activity between these systems that plays a very specific role in how we experience nostalgia.
Nostalgia counteracts loneliness.
Psychologists Xinyue Zhou and Ding-Guo Gao from Sun Yat-Sen University (along with Constantine Sedikides and Tim Wildschut from the University of Southampton) explored the relationship between loneliness and nostalgia by running a series of experiments where participants answered questions related to feelings of loneliness, social support, and nostalgia. The individuals in the study who felt the loneliest reported receiving the least amount of social support, however they were also the most nostalgic of the group.
Later, when nostalgia was induced in a number of the other participants, they perceived to have the greatest amount of social support. The results of these experiments show very real implications that nostalgia could potentially be used in cognitive therapy as a coping mechanism that individuals turn to when they are socially isolated or excluded.
Nostalgia is linked to resilience and perseverance.
Not only can nostalgia amplify perceptions of social support, which then counteracts feelings of loneliness, but it's also been linked to being more resilient.
The subjects of the experiments varied in age and background, some being children and others being middle-aged factory workers. The factory workers were also assessed on their resilience (their ability to recover from a traumatic event) and people who reported a larger sense of nostalgia were also more resilient in life.
Nostalgia fosters creativity.
A 2015 study publishing in the Journal of Experimental Social Psychology also linked nostalgia to openness to experience new things and creativity.
In two separate experiments, students were split into two different groups. One group was told to think of a past event that made them feel nostalgic and to really immerse themselves in that memory. Then they were told to write about it for five minutes. The other group was told to think about an "ordinary experience" that was not linked to any feelings of nostalgia and to write about it for five minutes as well.
The results showed those who were put into a nostalgic mindset before writing tended to be much more creative than those who wrote about an "ordinary experience."
