Bears Not Attracted to Menstruating Women

Despite campfire fears dating back to at least 1967, black bears and grizzly bears are not attracted to the odors of menstruation, according to a recent Yellowstone National Park report.

Polar bears may be interested in the smell of menstrual blood, the report found, but bears that roam in North America are not. Food is a much more important temptation for bears, according to the findings.

The idea that bears might preferentially attack menstruating women is not new. In 1967, a night of infamous grizzly bear attacks in Glacier National Park in Montana left two women dead. One woman was having her period, and the other was carrying tampons.
