Take a look to see how an adorable squirrel beats the summer heat. Squirrels have higher body temperatures than humans. That means they don’t get as hot as humans as quickly and aren’t as susceptible to the heat as people are. They also chill out through respiration. But that doesn’t rule out a squirrel getting heat stroke. It can happen, especially if the squirrel doesn’t escape the sun for treed or shady areas.
