A simple routine that works with your body’s own detox pathways.
Unlike traditional saunas that heat the air, infrared heaters warm your body directly, so sessions feel comfortable at about 110–150°F.
As infrared energy is absorbed, your core temperature elevates gradually, stimulating your cardiovascular system and increasing blood flow to deep tissues.
Sweat contains trace metals and compounds such as BPA. How much sauna adds to the body’s own detox pathways is still being studied.
Each finding names its study. They describe what researchers measured, not a promised result.
A systematic review found measurable arsenic, cadmium, lead and mercury in sweat, in some cases above blood or urine levels. Sweating is a minor route compared with the liver and kidneys, and more research is needed.
Regular sauna use is associated with fewer fatal cardiovascular events and better blood-vessel function in a 20-year Finnish cohort.
Frequent sauna use is associated with lower levels of C-reactive protein (CRP), a marker of inflammation.
Individual results may vary. The Finnish studies are observational, in middle-aged men using traditional high-heat saunas, and show associations rather than proof of cause. Heavenly Heat saunas are not medical devices and are not intended to diagnose, treat, cure or prevent any disease. If you are pregnant or have a heart or other medical condition, talk to your doctor before using a sauna.

I bought it for detox. I stayed for the sleep.
Best investment for my health. After just a few uses, my muscles feel less sore post-workout and my stress levels have dropped significantly. Easy to install and even easier to use.
I recommend Heavenly Heat to patients with chemical sensitivity. The clean construction and ultra-low EMF make it the only sauna I trust for my most sensitive patients.
I have MCS and was terrified of off-gassing. Zero issues. No smell, no reactions. This sauna has become my healing sanctuary. Thank you for building something truly clean.
The sleep improvement alone was worth it. I track with an Oura ring — my deep sleep went up 40% within the first two weeks of daily use.

Yes, you can! For the 2 Person Red Light Therapy Infrared Sauna we use the same far infrared heater layout as our 2 Person Far Infrared Sauna, with a red light / near infrared panel added on the front wall. On the panel you can use red light, near infrared, or both at the same time, with the far infrared heaters on or off. You can even remove the panel and replace it with the included glass panel, then use the red light and near infrared outside the sauna while the sauna remains completely functional.
Sweating is one of the ways your body clears what it does not need. A systematic review of published studies found trace metals, including arsenic, cadmium, lead and mercury, in human sweat (Sears et al., Journal of Environmental and Public Health, 2012). Regular sauna sessions are a simple way to sweat consistently. The cabin matters too: a sauna built with glues can add VOCs to the air while you sweat, which is why ours are built without them (see our VOC testing). A sauna supports your body's own processes; it is not a medical treatment.
The Red Light Sauna has two standard household plugs (NEMA 5-15): one for the infrared heaters and one for the red light panel. To run both safely you need either two separate 120V / 15A dedicated circuits, or one dedicated 120V / 20A circuit for both plugs. No 240V wiring or electrician is needed for most homes. See the electrical requirements, or send us a photo of your outlet and we will confirm before you order.
A traditional sauna heats the air to high temperatures, which then heats you. An infrared sauna warms you directly at a lower air temperature. The Finnish research used traditional saunas; infrared sessions raise heart rate in a similar way at lower temperatures.
Yes, red light therapy is considered safe when used as directed. It is non-invasive and does not emit harmful UV rays. However, avoid looking directly at the light and use eye protection if you experience any discomfort during therapy.
It is recommended to use your red light panel 3-7 times per week, with each session lasting 10-30 minutes.
Under 2 mG magnetic field and under 7 V/m electric field at the seating position, with grounded heaters, Faraday shielding and no RF. The EMF numbers were measured by Vitatech, an independent EMF lab (see the full results). Indoor air (VOCs) was tested separately by Primary Environmental (see the VOC results). We do not say "EMF-free": it is not a testable statement.
The main difference is the depth of penetration. Red light targets the skin's surface and shallow tissues, while near-infrared light penetrates deeper, reaching muscles, joints, and other internal tissues.
