How Infrared Differs From Hot Rock Saunas

Infrared saunas raise core temperature using light wavelengths rather than just ambient air heat.
That internal heating produces cardiovascular and metabolic adaptations similar to exercise.

INSIGHT

Infrared Spectrum Matters

Infrared spans near, mid and far bands with different penetration and energy.
Far-infrared matches human thermal emission and heats water molecules effectively but penetrates less deeply.

INSIGHT

EMF Is A Key Sauna Safety Issue

Early infrared tech emitted high EMF; modern designs must shield EMF for safety.
Unshielded heaters can reach EMF levels far above WHO guidance.
