Sauna

A sauna is a heated environment—either infrared or traditional—designed to raise core body temperature and promote sweating. Often paired with cold plunge as part of contrast therapy, sauna use is one of the oldest and most widely studied practices for supporting physical resilience, relaxation, and overall wellness.

The Science

Saunas work through hormesis—a controlled, beneficial stress that challenges the body and stimulates adaptive responses. Heat exposure increases heart rate and circulation, placing a mild cardiovascular load on the body similar to moderate exercise.
This heat stress stimulates the release of heat shock proteins, which play a role in cellular repair, protein maintenance, metabolic function, and stress resilience.
Infrared saunas heat tissues directly using specific wavelengths of light, while traditional saunas heat the surrounding air, leading to rapid sweating and cardiovascular activation. Both approaches train the body to become more adaptable and resilient when used consistently and appropriately.
