Is it true women actually live longer than men? Research shows that yes, in pretty much every country across the globe, women do live longer than men. Moreover, it doesn’t appear to matter if the person is living in a modern industrial nation with advanced healthcare or in earlier times with a general higher rate of mortality. However thankfully the gap has been narrowed somewhat with improved medicine, nutrition, and safer living conditions.
A recent study found females living longer than males does not just belong to humans. Johanna Stärk and her colleagues at the Max Planck Institute for Evolutionary Anthropology studied chromosomal sex differences in nearly 1,200 species in zoos around the globe. The study reports in 72% of those species, females lived 13 percent longer than males.
Researchers say this, along with other studies and statistical data, indicates lifespan may be based on more than lifestyle habits. The hypothesis is that the homogametic chromosomes of two X chromosomes in females may in itself provide a person some protection; and may actually slow aging on a molecular level. Males are heterogametic, with an X and a Y chromosome.
Thus, the difference between a male and female’s lifespan is most likely deeply embedded in evolution and not only shaped by sexual selection but parental care, and genetic factors linked to sex determination. The environment can also influence how large the gap in longevity becomes but cannot remove them entirely. Experts say the “contrasts between the sexes are not simply a product of circumstance but woven into our evolutionary past; and are likely to persist far into the future.”
However medical professionals stress that while biology may provide women with an advantage, lifespan is still greatly influenced by good lifestyle habits such as nutrition, exercise, stress and social connection. Most importantly longevity is ultimately determined on our sex, genetics, environment, access to medical care and lifestyle choices.
