U. S. researchers have said that women in Bangladesh who wear saris are literally wearing the answer to better health for themselves and their families.

Women who use a sari to filter household water protect their households from cholera, and even protect neighbors who don’t filter their water, Rita Colwell of the University of Maryland in College Park, said.

In 2003, Colwell and colleagues showed that teaching village women to filter water through folded cotton sari cloth reduced the incidence of cholera by 48 percent.
