Nostalgia Was Once a Deadly Disease. Here Is Its Strange Medical History.

The word exists in every language. The Germans call it Heimweh — home pain. The French called it le maladie du pays — the sickness of one's country. The Spanish had el mal de corazón — heart sickness. The English settled on homesickness, which has always been the plainest description and the least satisfying one, because it suggests the cure is simply going home.

For more than two centuries, European and American physicians believed that was exactly right — and that without the cure, the patient could die.

This is the medical history of nostalgia: a word invented in 1688 by a nineteen-year-old Swiss medical student, used to describe a diagnosable and sometimes fatal disease, treated with opium and bloodletting and in one extraordinary case with the threat of being buried alive, and eventually retired from medical classification — not because it was disproved, but because medicine outgrew the framework that had made it legible as a disease in the first place.

Basel, 1688: The Invention of a Word

Johannes Hofer was born in Mulhouse in 1669 and was nineteen years old when he submitted his medical dissertation at the University of Basel. He had noticed something that other physicians had observed but not named: that certain people — soldiers sent abroad, servants dispatched to foreign households, students relocated from their home cantons — sometimes became so ill from longing for home that they could not eat, could not sleep, could not function, and occasionally died.

Hofer's dissertation, Dissertatio Medica de Nostalgia, oder Heimwehe, published in Basel in 1688, gave the condition a name. He constructed it from two Greek roots: nostos, the Homeric word for homecoming — used in the Odyssey to describe Odysseus's return — and algos, meaning pain or grief. Nostalgia. The pain of return. Or more precisely: the pain of not being able to return.

Hofer described the condition as a "cerebral disease" caused by what he called the "continuous vibration of animal spirits" in the brain of the sufferer — an afflicted imagination fixed so intensely on the idea of home that it crowded out all other thought and eventually began to impair the body's physical functions. The symptoms he documented were specific and consistent: loss of appetite, pallor, general weakness, insomnia, palpitations, fever, and a tendency to confuse past and present — patients sometimes hallucinating familiar voices or the faces of people they loved.

Swiss mercenaries — young men from the Alpine cantons hired to fight in other nations' wars, a significant economic export of Switzerland in the seventeenth and eighteenth centuries — were nostalgia's earliest and most iconic victims. Separated from the specific landscapes of their mountainous homeland, these soldiers were considered particularly susceptible. Hofer's prescribed cure was also specific: send the patient home. The Alpine air, the familiar landscape, the proximity of family — these were the medicine. In cases where return was impossible, he suggested opium, purging, and time.

The Swiss Disease Spreads Across Europe

Hofer's dissertation moved through the European medical community with unusual speed for an era before mass communication. Within decades, other physicians across the continent were recognising nostalgia in their own patients, applying the diagnosis to soldiers, migrants, and domestics in their care, and debating its nature with the earnest rigour that characterised eighteenth-century medicine.

The condition became so strongly associated with the Swiss that it acquired several unofficial names: the Swiss Disease, Mal du Suisse, and Schweizerheimweh — Swiss homesickness. The association had a practical basis. Swiss mercenaries were scattered across the armies of France, Spain, the Netherlands, and the Italian states, far from the specific alpine environment they had grown up in. Some physicians theorised that the particular quality of Swiss mountain air — its altitude, its clarity, its cold — created a physiological dependency that made lowland displacement literally sickening. One doctor reportedly responded to this theory by placing nostalgic Swiss soldiers in tall towers, attempting to replicate the elevated perspective of their homeland.

A more alarming theory concerned music. The Kuhreihen — the traditional songs that Swiss cowherds used to call cattle for milking, heard in every Alpine valley — were said to trigger immediate and severe nostalgia in Swiss troops when played abroad. According to some accounts, performing these songs in the presence of Swiss mercenaries was made a punishable offence, on the grounds that the music constituted a kind of biological weapon against the army's own soldiers. The historical record on this specific claim is contested, but its persistence in multiple sources across several decades indicates how seriously the idea of nostalgia as a physiologically triggered condition was taken.

Nostalgia was not only a Swiss condition, however. As the eighteenth century progressed, French and German physicians documented cases across a wider population — migrants, servants, students displaced from their home regions — and debated whether it was a distinct disease or a form of the ancient diagnosis of melancholia. By the era of the French Revolution and the Napoleonic Wars, military medical records were documenting thousands of cases, and nostalgia was sometimes recorded as a cause of death in official military records.

The treatments on offer during this period reflected the medical frameworks of the age. Bloodletting. Purgatives. Opium. Leeches. "Warm hypnotic emulsions." And, in one of the more dramatic entries in the medical history of the disease: in 1733, a Russian military commander, observing his troops suffering from nostalgia, is reported to have buried one nostalgic soldier alive as a warning to the others. During the French Revolution, physician Jourdan Le Cointe publicly prescribed what he described as "pain and terror" as a cure — the logic apparently being that sufficient external suffering would overwhelm the internal suffering of homesickness. There is no record of either treatment producing the desired outcome.

America's Civil War: The Last Great Epidemic

By the time the American Civil War began in 1861, nostalgia had been a recognised medical diagnosis for nearly two centuries. Union and Confederate army physicians both inherited it as a clinical category, and they applied it extensively. The armies were composed primarily of young men — many of them agricultural workers and rural volunteers, away from their families and home communities for the first time in their lives — and the conditions of the war produced nostalgia in significant numbers.

The official Medical and Surgical History of the War of Rebellion, published in 1888, recorded 5,213 cases of nostalgia among white Union soldiers and 58 deaths attributed to the condition, along with 334 cases and 16 deaths among Black Union soldiers. These are the documented figures. Historians note that the actual prevalence was almost certainly higher — many cases were absorbed into broader diagnoses or went unrecorded.

Among the documented deaths was Frederic Whipple, a young Vermont man who had recently married when he was recruited into the Union Army's Tenth Vermont Infantry Regiment in 1862. He presented to an army surgeon exhibiting no physical illness, only an extreme and overwhelming desire to return home. He was moved to the infirmary. There, according to the chaplain Edwin Haynes's account, he refused all nursing care. After a few days he died, moaning continuously: "I want to go home. I want to go home." His death was recorded as "a clear case of nostalgia."

The cultural attitude toward nostalgia in mid-nineteenth-century America was notably different from the military responses of earlier centuries. Susan Matt, a history professor at Weber State University in Utah who has studied Civil War nostalgia extensively, has noted that loving home was understood in that era as part of being a morally upright person. Nostalgia, in this context, was almost a virtuous illness — evidence that the sufferer cared about the right things. This attitude made some Civil War physicians more sympathetic to nostalgic soldiers than their European predecessors had been, though the taunting of homesick men as weak-minded was also documented throughout the war's records.

How It Disappeared From Medicine — and Reappeared in Culture

Nostalgia did not leave medical classification because someone disproved it. It left because the conceptual architecture that had made it legible as a disease was dismantled from underneath it.

Through the second half of the nineteenth century, the germ theory of disease — the understanding that illness was caused by specific pathogens rather than imbalances of humours, spirits, or environmental conditions — reorganised medicine from the ground up. Bacteriology, cellular pathology, and the emerging science of psychiatry created new categories and new taxonomies. Nostalgia was not infectious. It had no identifiable pathogen. Its symptoms overlapped uncomfortably with melancholia, with neurasthenia, and with what would later be identified as depression. By the 1870s it had effectively ceased to exist as a distinct medical diagnosis, absorbed into broader categories that the new medicine considered more precise.

What happened to the phenomenon itself was more interesting. As nostalgia left the medical textbooks, it entered the cultural imagination — and changed meaning as it did so. The Romantic movement had already begun reframing intense longing not as pathology but as a mark of sensibility, of depth, of a superior relationship to memory and feeling. Byron and Rousseau pined for lost landscapes and lost youth. Frédéric Chopin, composing in exile in Paris, wrote mazurkas that his contemporaries heard as expressions of longing for a Poland lost to partition — the rhythmic patterns and modal inflections of his homeland transmuted into art.

By the twentieth century the transformation was complete. The word Hofer had coined to describe a potentially fatal disease of displacement had become, in common usage, the description of a pleasantly bittersweet feeling — a fondness for the past, for objects and experiences associated with earlier life, for summers that seemed longer and moments that seemed bigger. The disease became an emotion. The emotion became, in the words of Harvard scholar Svetlana Boym, "the incurable modern condition."

Boym, in her 2001 work The Future of Nostalgia, distinguished between what she called reflective nostalgia — a longing that acknowledges the past cannot be recovered and draws meaning from that acknowledgment — and restorative nostalgia, which attempts to reconstruct the past as it was, or as it is imagined to have been. The former, she argued, could be a source of creativity, perspective, and genuine self-knowledge. The latter tended toward myth and rigidity.

Contemporary research has taken the question in a different direction entirely. Clay Routledge, a psychology professor at North Dakota State University and author of Nostalgia: A Psychological Resource, has documented through experimental studies that nostalgia — contrary to Hofer's original observations — tends to function as a largely positive psychological state. Nostalgic feelings increase during periods of instability and transition. Rather than deepening distress, they appear to help people reorient: increasing reported feelings of social connection, boosting mood, and generating what Routledge's participants described as a sense of being inspired and motivated toward the future.

The disease that Hofer invented in 1688 — the one that killed Frederic Whipple in a Vermont infantry hospital in 1862 — has become, three centuries later, something researchers describe as a psychological resource. The pain of homecoming has become, for most people most of the time, something closer to its opposite: a warm and temporary place to rest before returning to the present.
