Filtered Water in Childhood Adds Months to Lifespan, Study Finds

A new study published in the American Journal of Health Economics finds that drinking filtered water early in life can extend a person's lifespan by an average of 3.2 months.

Researchers analyzed Social Security death records for American men born between 1975 and 2005, cross-referencing their birth cities with historical water filtration data. The results show that clean water access in childhood not only adds to longevity but also sets off a positive chain reaction for physical and socioeconomic development.

According to the study, early exposure to filtered water was linked to increased height, higher education levels, and greater income later in life.

The paper is part of the American Mortality Project, which examines how early-life conditions shape the modern American lifespan.

Because the data only includes American men from a specific historical period, the findings may not apply to women, rural communities, or developing nations.
