About The Joy of Sweat: The Strange Science of Perspiration

An Outside Magazine 2021 Science book pick One of Smithsonian's 10 Best Science Books of 2021 A taboo-busting romp through the shame, stink, and strange science of sweating. Sweating may be one of our weirdest biological functions, but it’s also one of our most vital and least understood. In The Joy of Sweat , Sarah Everts delves into its role in the body—and in human history. Why is sweat salty? Why do we sweat when stressed? Why do some people produce colorful sweat? And should you worry about Big Brother tracking the hundreds of molecules that leak out in your sweat—not just the stinky ones or alleged pheromones—but the ones that reveal secrets about your health and vices? Everts’s entertaining investigation takes readers around the world—from Moscow, where she participates in a dating event in which people sniff sweat in search of love, to New Jersey, where companies hire trained armpit sniffers to assess the efficacy of their anti-sweat products. In Finland, Everts explores the delights of the legendary smoke sauna and the purported health benefits of good sweat, while in the Netherlands she slips into the sauna theater scene, replete with costumes, special effects, and towel dancing. Along the way, Everts traces humanity’s long quest to control sweat, culminating in the multibillion-dollar industry for deodorants and antiperspirants. And she shows that while sweating can be annoying, our sophisticated temperature control strategy is one of humanity’s most powerful biological traits. Deeply researched and written with great zest, The Joy of Sweat is a fresh take on a gross but engrossing fact of human life.
