This presentation explores humidity and diffused light as queer atmospheric conditions that disrupt normative expectations of comfort, hygiene, and spatial clarity within interior environments. Drawing on queer theory—especially the work of José Esteban Muñoz and Sara Ahmed—it reframes these elements as sensorial agents that foster slowness, softness, and porous relationality. Through case studies and speculative design proposals, it examines how vapor, mist, and light can be harnessed to produce erotically charged, ecologically responsive interiors. In doing so, the paper proposes atmosphere as a critical and political design tool rather than a passive environmental backdrop.
