The Morning Kiss Study: A Longevity Myth Debunked

You've probably heard this one before: men who kiss their wives goodbye in the morning live five years longer than those who don't. It's been shared millions of times across social media, cited in relationship advice columns, and even mentioned by marriage counselors. There's just one problem—the study behind it is basically a ghost.

The claim supposedly comes from research by Dr. Arthur Szabo, a psychology professor at the University of Kiel in Germany, who allegedly collected data for two years from physicians, psychologists, and insurance companies in the 1980s. His findings were supposedly published in a West German magazine called Selecta. The study didn't just claim kissing husbands lived longer—it also said they earned 20 to 35 percent more money, used less sick time, and were even less likely to get into car accidents.

Where's the Evidence?

Here's where things get sketchy. Nobody can actually find this study. There's no verifiable documentation, no methodology description, no peer review, nothing. When skeptics tried to track down the original research, they hit dead ends. No questionnaires, no experimental design, no observational data—just claims without proof.

Academic analyses have noted that while the outcomes "seemed reasonable," the research "failed to prove with a research study" what it claimed. Even the American Journal of Medicine acknowledged these "kissing facts" were "not necessarily evidence-based" when discussing the claim in scientific literature.

Why We Want to Believe It

The morning kiss myth persists because it feels true. Affection, emotional connection, and positive relationship dynamics do correlate with better health outcomes—that part isn't fiction. Research on oxytocin, stress reduction, and marital satisfaction supports the general idea that healthy relationships contribute to longevity.

Dr. John Gottman, a legitimate marriage researcher, has mentioned similar findings about kissing and longevity, though he cites four years rather than five. But even Gottman's claim lacks the rigorous, replicable research you'd want before accepting such a specific number as fact.

The Real Takeaway

Does kissing your spouse goodbye matter for your health? Probably, in the sense that any affectionate behavior that strengthens emotional bonds and reduces stress has positive effects. But the specific claim about five extra years? That's marketing, not science.

The morning kiss myth is a perfect example of how unverified claims spread when they align with what we want to believe. Next time you see a suspiciously specific health claim citing a decades-old foreign study, it's worth asking: where's the actual evidence?
