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 five 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.

Pre-, During-, and Post-Session Rituals

Before

  • Hydrate with 8–16 oz water, preferably with added electrolytes (especially if prone to heavy sweating)
  • Small protein snack optional
  • Avoid alcohol or vasodilating substances

During

  • Focus on slow, nasal breathing—this optimizes vagal tone and enhances heat adaptation
  • Aim for a steady, manageable sweat, not a drenching marathon
  • Stop immediately if dizzy, dehydrated, or lightheaded

After

  • Rinse with cool or tepid water to remove sweat solutes and toxins excreted through the skin
  • Replenish with protein, electrolytes, and gentle movement (e.g. walking or light stretching)
  • Optional add-ons: legs-up-the-wall, breathwork, or guided meditation for integrative recovery

Safety notes

Check with a clinician if pregnant; febrile/ill; have unstable cardiovascular disease, uncontrolled blood pressure, a history of syncope, implanted electronic devices, or take heat-sensitive medications.
