Air Conditioning Makes Us Miserable: The Open Window Effect

Send us Fan Mail Why are so many offices freezing in July? We can now engineer any indoor temperature, yet millions of us shiver at our desks. This episode unpacks the physics of air conditioning, a "thermal sponge" that moves heat rather than making cold, and the 1998 UC Berkeley study by Richard de Dear and Gail Schiller Brager that changed how we think about comfort. In this episode: How compressors, condensers and expansion valves really work The "static model" of comfort, and why it treats people as passive 21,000 observations from 160 buildings across four continents Behavioral, physiological and psychological adaptation The "semantic artifact," and why we crave contrast, not neutrality Adaptive opportunity: a window you can open widens comfort by ~70% Why sealed buildings can make us more sensitive Listen, read the essay, and support the Heliox community.

Breathe Easy, we go deep and lightly surface the big ideas. Support the show Disclosure: This podcast uses AI-generated synthetic voices for a material portion of the audio content, in line with Apple Podcasts guidelines. We make rigorous science accessible, accurate, and unforgettable. Produced by Michelle Bruecker and Scott Bleackley, it features reviews of emerging research and ideas from leading thinkers, curated under our creative direction with AI assistance for voice, imagery, and composition. Systemic voices and illustrative images of people are representative tools, not depictions of specific individuals. We dive deep into peer-reviewed research, pre-prints, and major scientific works—then bring them to life through the stories of the researchers themselves. Complex ideas become clear. Obscure discoveries become conversation starters. And you walk away understanding not just what scientists discovered, but why it matters and how they got there. Independent, moderated, timely, deep, gentle, clinical, global, and community conversations about things that matter. Breathe Easy, we go deep and lightly surface the big ideas. Spoken word, short and sweet, with rhythm and a catchy beat. http://tinyurl.com/stonefolksongs
