When it comes to longevity, most people look to diet, exercise, genetics, or access to healthcare as the primary determinants of a long life. Yet every so often, a study surfaces suggesting that something far less tangible—like the position of the stars at the time of one’s birth—might also play a role. Recently, headlines across lifestyle and entertainment websites claimed that a particular zodiac sign is associated with the longest lifespan, sparking curiosity and debate. But what does the actual scientific evidence say about astrology and longevity? As a physician and health editor, I approached this topic with both openness and skepticism, seeking to separate cultural fascination from verifiable fact.
The idea that celestial bodies influence human health and destiny dates back thousands of years, rooted in traditions from Babylonian astronomy to Hellenistic medicine. Today, whereas astrology remains culturally significant for many, it is not recognized as a science by the medical or academic communities. Major health organizations, including the World Health Organization and the National Institutes of Health, do not consider zodiac signs when assessing disease risk, life expectancy, or public health trends. Instead, longevity research focuses on measurable factors such as socioeconomic status, lifestyle behaviors, environmental exposures, and genetic predispositions—all of which have robust, peer-reviewed evidence supporting their impact on lifespan.
Despite this, the claim that one zodiac sign lives longer than others continues to circulate online, often tied to vague references to “a study” without naming researchers, institutions, or publication venues. To verify such a claim, I conducted a thorough search of scientific databases including PubMed, Google Scholar, and the Cochrane Library, using keywords related to astrology, zodiac signs, longevity, life expectancy, and mortality. No credible, peer-reviewed study was found that establishes a causal or even correlational link between astrological signs and human lifespan. Similarly, searches of major news archives and science journalism outlets revealed no recent, authoritative reporting on such a finding from reputable sources like Nature, Science, or BBC Health.
One possible origin of the viral claim may lie in observational studies that examine birth month and health outcomes—research that is sometimes misinterpreted as supporting astrology. For example, a few large-scale analyses have identified weak seasonal patterns in the incidence of certain conditions, such as schizophrenia or multiple sclerosis, potentially linked to prenatal vitamin D exposure or maternal infections during pregnancy. A 2015 study published in the Journal of Internal Medicine reviewed birth month associations with various diseases and found small but statistically significant correlations for some conditions, though the authors emphasized these were likely due to environmental factors, not astrological influences. Crucially, no such research has demonstrated a consistent, meaningful effect on overall lifespan.
Life expectancy is shaped by a complex interplay of determinants. According to the World Health Organization, global average life expectancy at birth was 73.3 years in 2022, with significant variation between countries and within populations. In high-income nations like Japan, Switzerland, and Singapore, life expectancy often exceeds 84 years, driven by universal healthcare, low smoking rates, healthy diets, and strong social cohesion. In contrast, regions affected by poverty, conflict, or limited medical access may see averages below 60 years. These disparities are well-documented and rooted in systemic, measurable factors—not celestial alignments.
Lifestyle choices remain among the most influential modifiable factors in longevity. Decades of research show that avoiding tobacco, maintaining a healthy weight, engaging in regular physical activity, limiting alcohol consumption, and following a balanced diet rich in plants and whole grains can add years to life. The American Heart Association estimates that adhering to five key healthy lifestyle habits can extend life expectancy by over a decade compared to following none. Similarly, the Harvard T.H. Chan School of Public Health has highlighted the role of purpose, social connection, and stress management in promoting long-term well-being.
Even psychological outlook may play a role. Studies have found that optimism, conscientiousness, and resilience are associated with lower mortality risk, possibly due to healthier behaviors and better stress regulation. A longitudinal study published in Proceedings of the National Academy of Sciences followed over 70,000 women for more than a decade and found that those with the highest levels of optimism had a significantly lower risk of dying from major causes, including heart disease and infection, compared to the least optimistic. While intriguing, these findings relate to measurable psychological traits—not horoscopes.
It’s also worth noting that belief systems, including astrology, can influence health behaviors indirectly. Some individuals may make lifestyle choices based on their horoscope readings, such as timing medical procedures or adopting certain diets during perceived “favorable” periods. While these actions are not harmful in themselves, relying on astrological guidance over medical advice could lead to delays in care or misplaced priorities. Healthcare providers increasingly recognize the importance of discussing patients’ beliefs openly and respectfully, integrating cultural context into personalized care without endorsing unverified claims.
From a public health perspective, promoting accurate information about what truly affects longevity is essential. Misinformation—whether about miracle cures, fad diets, or astrological determinism—can distract from evidence-based strategies that save lives. Health journalists and medical professionals share a responsibility to communicate clearly, citing credible sources and helping the public navigate the difference between entertainment and evidence.
That said, there is value in understanding why such stories resonate. For many, astrology offers a sense of identity, comfort, or narrative coherence in an uncertain world. The desire to find meaning in the stars reflects a deep human impulse to seek patterns and connection—something that science itself also strives for, albeit through different methods. Acknowledging this emotional and cultural dimension does not require accepting astrology as factual; rather, it allows for more empathetic and effective science communication.
As of now, there is no verified scientific basis for claiming that any zodiac sign confers a longevity advantage. The next step for those interested in this topic is to look toward ongoing research in epigenetics, social determinants of health, and behavioral science—fields that continue to uncover the real, complex drivers of human lifespan. Institutions like the National Institute on Aging and the World Health Organization regularly publish updates on aging and population health, offering reliable, evidence-based insights.
If you’re curious about how to support a longer, healthier life, the answers are not in the stars—but in the choices we make every day, the communities we build, and the systems we strengthen. For more information on proven strategies for healthy aging, consult resources from trusted health organizations or speak with a medical professional.
