SweatHouz on Tennyson is the kind of place that turns a Tuesday recovery session into a whole ritual. This contrast therapy studio keeps it focused: infrared sauna heat followed by cold plunge immersion, the cycle that's taken over wellness culture for good reason. The Tennyson location sits right in the Berkeley neighborhood, which means you can walk out glowing and grab coffee on the strip without breaking the vibe. The space is clean, minimal, and intentional. No gym chaos. Just heat, cold, and the kind of reset your nervous system has been asking for. Perfect for anyone deep into recovery, sober-curious weekends, or just looking to replace the Sunday hangover with something that actually feels good.
