<p>This article proposes the notion of ‘sweaty bodies’ as a feminist approach to socioenvironmental politics, which tracks the unequal distribution of sweat on different human and nonhuman bodies. In some situations, the presence of sweat diminishes the vitality of bodies, while in others, it expresses empowerment. The circulations of sweat thus partition bodies with political implications. After situating sweaty bodies within the hydrofeminist strand of contemporary feminist theory, I add two critical ecofeminist insights of work as domination and an ethnographic methodology. Next, I illustrate the unique analytical advantages of thinking with sweat in three recent field studies. First, a sweatshop in France shows how sweat diminishes the vitality of human bodies, before the second case of a gym in Mozambique demonstrates the capacity of sweat to foster joy. Thirdly, the phenomenon of ‘plant sweat’ in Indonesia denotes that sweat nourishes both human and nonhuman bodies. I end by suggesting that the ‘politics of sweat’ is irreducibly ethical, implying that the normative goal must be that all bodies, human and nonhuman, sweat in the most empowering ways.</p>
