Everybody sings! The how and the wow of your voice

If our bodies are 98 degrees, why does it feel so hot outside?

98.6 degrees is hot. If it were that hot outside, you’d be sweaty and want to go jump in a nice cold pool. But the insides of our bodies are that hot all the time! And that’s because there’s a lot going on in there that creates heat. In this episode, Molly and co-host Saathvik find out how our bodies keep our insides at a nice steady temperature (and why that’s harder to do when it’s hot outside!). And we’ll talk with Dr. Joe Alcock about why humans and lots of other animals get fevers. Plus, a new mystery sound guaranteed to make you sweat!
