Do Autumn Babies Live Longer Than Babies Born in Other Seasons?

By Meredith Carroll |


Autumn is certainly a colorful time to be born

Does the season in which babies are born affect their life span?

Quite possibly, according to a study out of the University of Chicago that was reported in the Journal of Aging Research.

The findings, based on data from more than 1,500 people born between 1880 and 1895 — and compared with the data and birth months and life spans of nearly 12,000 centenarian’s siblings and spouses — showed that babies born in three particular months had a 40 percent greater chance of living until the age of 100 than babies born in three other months

What birth months increase a baby’s chance of hitting triple digits, and which three months are least likely to produce cenenarians?

September, October and November saw the birth of the most centenarians.

March, May and July produced babies 40 percent less likely to live to see 100.

According to, the study didn’t exactly know why fall babies fared better at longevity, but the researchers had some theories:

It’s possible, for example, that pregnant mothers had access to different levels of nutrition at different times of year in the late 1800s. Seasonal rates of infection may have also influenced fetuses in the womb, with vulnerability peaking during certain developmental periods.

Weather conditions at conception or birth could have an effect, as well. In the autumn in many parts of the United States, temperatures are neither too stressfully hot nor too stressfully cold. Several factors could combine to make fall babies especially hearty.

While the data studied was clearly old, the takeaway seems to be that “conditions we experience extremely early in life may influence our health and survival many decades later.”
