Bears need baths too, but not to wash dirt from between their hairy toes. Instead, taking a dip in a cool pool of water helps the large, furry mammals reduce their body temperature.

Turns out, a cool dip in a pool of mountain spring water is the perfect solution during hot summer days. As the climate warms, temperature-controlling plunges may be especially important for females with cubs and those that are pregnant. That’s because when pregnant or lactating, female bears generate more heat.

The work involved a couple of unusual scenarios. One part of the study required shaving a 2-inch square clump of hair off the grizzlies to measure the amount and density of their fur.

The animals also walked on treadmills to measure their oxygen consumption.
