Natürlich durchatmen — Healing air and stillness in Aalen’s Heilstollen.
Beneath Aalen, the Heilstollen offers an almost otherworldly pocket of climate: air that is nearly free of dust, a steady 11°C and about 98% relative humidity. In this near-sterile, humid environment visitors are guided through gentle breathwork before settling into a restorative rest period — a short, focused therapy designed to calm the nervous system and support respiratory health.
