The fitness world isn’t short on polarising debates. High-intensity vs. low-impact. Mat vs. Reformer. Garmin loyalists vs. “I just go by feel” purists. But there’s perhaps no deeper (or sweatier) divide than the one between those who swear by a heated studio and those who feel their best when the thermostat stays firmly low.
That heat-based workouts are having a moment is undeniable. Infrared saunas, traditional steam rooms and contrast therapy are no longer reserved for elite athletes - they’ve gone mainstream. A 2018 study published in Mayo Clinic Proceedings suggests that heat exposure could support cardiovascular health, reduce inflammation, and enhance both endurance and recovery. Sauna sessions are even doubling as social events, with brands like Arc hosting after-dark events that blend heat therapy with music, DJs, and community.
