People from a traditional hunter-gatherer group in Cameroon don’t see their blood pressure go up as much with age compared to city-dwelling adults from another group, suggesting that living a traditional lifestyle might help keep blood pressure in check as people get older.

City-living Bantu adults in Cameroon are way more likely to have high blood pressure than Pygmy people in the countryside — 28% vs just 3.3% — suggesting that city life might be raising their risk.

Even in remote tribes that live totally naturally, blood pressure still goes up as people get older — which might mean aging itself, not just modern life, causes this change.

People's blood pressure tends to go up as they get older—even if they don't eat processed food, sit around a lot, or follow a Western diet—so aging itself might be the reason, not just modern lifestyles.

In some remote communities that live without modern industrial lifestyles, people don’t get high blood pressure as they age — and it’s super rare, suggesting it might not be a normal part of aging everywhere.
