SAUNA
In keeping with a modern biohacking approach, the sauna can be used specifically to optimize sleep. The physiological effects are well documented: A sauna session in the late afternoon or early evening initially significantly increases core body temperature. In the hours following, it drops measurably – a temperature profile that corresponds to the natural process of falling asleep.
Studies show that this thermoregulatory dynamic can shorten the time to fall asleep and prolong deep sleep phases .
Saunas are also relevant from a neurophysiological perspective: Exposure to heat releases endorphins and boosts parasympathetic activity —both factors that positively influence sleep. We consciously utilize these effects in our Sleep Retreat. In addition to traditional saunas, we offer steam baths and gentle sanariums, whose mild temperatures are particularly well-suited for evening treatments.
Additionally, the treatment can be combined with cold pulses or targeted breathing techniques to increase vagal tone . This turns a sauna session into an effective regenerative activity with tangible benefits for sleep.
