For the past several years, our preferred way to greet the New Year has been to indulge in a few days’ soak in the Calistoga hot springs at the tip of Napa Valley, just 30 miles east of the wowhaus studio on the other side of the Mayacamas Range. The annual ritual gives us a chance to recalibrate and slow down, modulating our body temperatures as we shift from pool to pool and follow the sun on its low arc across a clear winter sky. The days pass in pace with the conduction of heat and the evaporation of mineral-rich water, leaving us feeling like much simpler, happy organisms.
