Far infrared (FIR), delivered by Relax’s patented, FDA-registered semiconductor generators (100% FIR in the 7–14 μm band, >40 mW/cm²), is a powerful therapy you can do at home for about thirty cents of electricity per session. The generators power up fast; you won’t see light—FIR is outside the visible spectrum—but you’ll feel gentle, penetrating warmth as it begins interacting with the body’s water within minutes. Work toward 15–30 minute sessions, even if you start at five. Handy tip: if you’re getting too warm, crack the zipper to vent and continue comfortably. Note: venting will lower the FIR density at your skin—so you’ll absorb a bit less than with the tent fully closed—but you’ll still receive plenty. Comfort is the priority.
