Why Fall Births May Be Linked to Longevity
What months show a connection to living to 100?
A recent study suggests a link between birth month and exceptional longevity. Researchers analyzed data from 1500 centenarians born in teh United States between 1880 and 1895, comparing it to data from their siblings and spouses who did not live as long. This allowed them to isolate the impact of birth date, minimizing the influence of shared living conditions. the study found that a disproportionate number of centenarians were born in the fall – specifically, between September and November – while births in spring and summer were less common. As the study authors state, this suggests the month of birth can influence lifespan, even when accounting for shared environments and family traits.
What could explain this trend?
The reasons behind this phenomenon remain a mystery, but researchers have several hypotheses. One possibility relates to poliovirus epidemics, wich peaked in July and August. Exposure to the virus during the second trimester of pregnancy may have had long-term effects. Another theory focuses on seasonal vitamin deficiencies during fetal development and infancy, possibly impacting future health. Temperature and sun exposure are also being considered as contributing factors.
Important Note: While the study reveals an interesting correlation, it’s crucial to remember that birth month is just one factor influencing longevity. Many lifestyle choices, such as diet and exercise, play a significant role in how long a person lives. Being born in the fall doesn’t guarantee a long life, but it may offer a slight advantage.
