Many Saunas Off-Gas Glue and Only Shield Half the EMF Spectrum. Here's What We Built Instead.
Before You Invest in a Sauna, Do Your Research
After the basics, such as size, heat type, and electrical requirements, there are two additional criteria to strongly consider. First, does the sauna’s construction expose you to additional chemicals? Many saunas on the market are still built with wood glues that off-gas chemicals when heated. Second, to what extent does the sauna expose you to additional and unnecessary EMFs?
In a 20-year study of more than 2,300 men, those who used a sauna 4–7 times a week had far lower rates of fatal heart events than those who went once a week.
Regular sauna use is associated with a lower risk of all-cause mortality. Clean heat lets you make it a daily habit without adding toxins to your body.
Heat after training increases blood plasma volume, which helps carry oxygen to working muscles. In one study, runners who used a sauna after workouts lasted longer before hitting exhaustion.
Sweat is one of the ways your body releases trace metals like lead and cadmium. Clean air in the cabin matters too, which is why we build without glue.
In a 20-year Finnish study, men who used a sauna 4–7 times a week had a significantly lower risk of dementia and Alzheimer's disease.
Frequent sauna use is linked to a lower risk of both acute and chronic respiratory disease. Breathing air free of VOCs during every session makes that benefit count.
An evening session helps your body wind down, easing stress and setting you up for deeper sleep.
Which Type of Sauna Is Right for You?
Infrared, traditional, combination, and red light saunas each deliver heat differently and support different health outcomes. Here's how to tell them apart.
Infrared Sauna
Uses infrared panels to warm the body directly at lower cabin temperatures — the style most associated with detox and recovery protocols.
Traditional Sauna
Produces high ambient heat using an electric or wood-burning heater — the style most associated with long-term cardiovascular and brain health research.
Combination Sauna
Combines infrared and traditional heat in a single cabin — offering the benefits of both modalities without requiring two separate units.
Red Light + Infrared Sauna
Integrates true red light therapy panels directly inside the sauna cabin — a Heavenly Heat first.
Many Saunas Are Held Together With Glue. Ours Isn't.
At high heat, the materials inside your sauna become the air you breathe. Most buyers never think to ask what's holding their sauna together — and most manufacturers are counting on that.
What are VOCs — and why do they matter in a sauna?
VOCs (Volatile Organic Compounds) are harmful chemicals released by materials like glues, stains, and plastics. At the elevated temperatures inside a sauna, these chemicals off-gas at a higher rate — meaning you're actively inhaling them during the session that's supposed to be improving your health.
What Heavenly Heat uses instead:
- 100% solid Canadian Hemlock and Poplar — non-resinous woods that are naturally hypoallergenic
- Zero glues, zero wood adhesives, zero chemical finishes
- No plywood. No stains. Nothing to off-gas.
- Independently tested for VOCs by Primary Environmental, a third-party lab
The result: A sauna environment with no hidden chemical exposure — clean air, every session.
Built for chemically sensitive (MCS) patients since 1988.
Every Premium Sauna Brand Claims "Low EMF." Almost None of Them Are Measuring It Correctly.
There are two types of electromagnetic fields inside a sauna. Most brands only address one. Here's what that means — and why it matters.
EMF stands for Electric and Magnetic Fields. Prolonged or high-level exposure to electromagnetic fields has been associated with fatigue, headaches, cardiovascular stress, and other health concerns.
When you're sitting in a sauna for 20–45 minutes per session, EMF exposure is not a trivial variable.
Most brands measure only the magnetic field from the heaters, then advertise a single low number. The electric field — the other half of the spectrum — is left unshielded and unreported.
A "low EMF" label that only covers half the spectrum is not a low EMF sauna.
We shield both the electric and magnetic fields with a built-in Faraday cage, then have our saunas independently tested and publish the full results.
Both fields shielded. Independently tested. Full results published.
We've Been Building the Cleanest Sauna on the Market Since Before "Non-Toxic" Was a Marketing Term
Founded in 1988 with one guiding principle: detox should never introduce more toxins.
38 years and 5,000+ customers later, that standard hasn't changed. We still use zero glues, zero wood adhesives, and zero chemical finishes. We still have our saunas independently tested for EMF and VOCs. And we still answer the phone.
Category firsts:
- First non-toxic sauna brand, originally built for detox clinics and chemically sensitive patients
- First to integrate true red light therapy directly inside the sauna cabin
- One of the first to build a combination sauna with both infrared and traditional heat in a single unit
- Independently third-party verified by Primary Environmental
What "trusted by doctors" actually means:
We don't use that phrase as a marketing decoration. Heavenly Heat was recommended by physicians to patients with Multiple Chemical Sensitivity (MCS) before most sauna brands existed. That trust was earned through materials integrity — not advertising.
In 2023, founder Bob Morgan retired. His standards didn't.
