Infrared saunas have become one of the most powerful wellness tools for recovery, detoxification, circulation, and long-term brain and metabolic health. But as demand has grown, so has concern around EMF exposure, build quality, materials, and safety.
In this Clearlight Sauna review, we’ll take a deep, honest look at one of the most popular infrared sauna brands on the market. This review is based on months of real-world use in both a commercial gym setting and a home environment, along with live EMF testing using a meter.
We’ll cover:
- What the Clearlight Sauna does well
- Where it falls short
- Real EMF readings (not marketing claims)
- Who this sauna is best for
- Whether it’s actually worth the investment
What Is the Clearlight Sauna?
Clearlight is a premium infrared sauna brand best known for its Sanctuary series, which ranges from one-person units to large family-sized saunas.
The model reviewed here is the Clearlight Sanctuary 1, officially marketed as a one-person infrared sauna, though in practice it can fit two people comfortably if one person is smaller.
Clearlight saunas are designed for:
- Home use
- Gyms and wellness centers
- Recovery and longevity protocols
Real-World Experience: Home + Gym Use
One of the strengths of this review is that the Clearlight Sauna wasn’t just tested briefly.
It was used:
- For several months at Allegiant Strength Gym in San Antonio, Texas
- Previously in a home setting in Michigan
This gives a much clearer picture of:
- Build quality over time
- Heating performance
- Comfort
- EMF exposure consistency
Build Quality & Materials
Cedarwood Construction
One of the biggest positives of the Clearlight Sauna is its cedarwood construction.
Why cedar matters:
- Naturally water-resistant
- Handles moisture and sweat well
- Resistant to warping
- Smells incredible
The aroma inside the sauna is noticeable in a good way and adds to the overall experience.
Low Off-Gassing & Clean Craftsmanship
A common concern with infrared saunas is toxic off-gassing from:
- Glues
- Adhesives
- Cheap composite woods
In the Clearlight Sauna:
- There are very few visible glues
- Most of the structure appears to be solid wood
- Any adhesives used are sealed internally
This significantly reduces chemical exposure while heating.
Interior Features & Controls
Inside the Clearlight Sanctuary 1, you’ll find:
- Digital control panel
- Interior color-changing light
- Exterior ambient lighting
- Built-in speakers
- Ventilation panel
- Storage shelf
The control panel allows you to:
- Set temperature
- Adjust session time
- Switch between Fahrenheit and Celsius
- Control lighting
Everything is intuitive and easy to use.
Full Spectrum Infrared Panels Explained
Clearlight uses full-spectrum infrared panels, which means they emit:
- Near infrared
- Mid infrared
- Far infrared
You can adjust the infrared intensity to:
- 25%
- 50%
- 75%
- 100%
The reviewer keeps it at 100%, since higher intensity allows you to get more benefits in less time.
EMF Testing: Real Results (Not Marketing)
One of Clearlight’s biggest claims is low EMF exposure—and this is where many sauna brands exaggerate.
To verify this, an EMF meter was used inside the sauna during operation.
How EMFs Were Measured
- Blue = low / safe
- Red = elevated
Results Inside the Sauna
- Middle of the sauna: Blue (very low EMFs)
- Side walls: Mostly blue
- Infrared panels: Some red, typically between 20–80
- Control panel area: Higher readings (~150–160)
This is expected. Any electrically powered sauna will have higher EMFs near control panels.
Key Takeaway on EMFs
- EMFs are present (they always are)
- Levels are low compared to most saunas
- EMFs drop quickly when sitting slightly away from panels
👉 Best practice: sit slightly away from infrared panels for lowest exposure.
Overall, Clearlight’s low-EMF claim holds up.
Health Benefits of Using the Clearlight Sauna
Infrared saunas provide a wide range of benefits, many of which the reviewer personally experienced.
Key benefits include:
- Muscle recovery
- Improved circulation
- Lymphatic drainage
- Skin health
- Immune system support
- Brain health support
- Detoxification via sweat
Infrared saunas are also widely used in:
- Alzheimer’s and dementia support protocols
- Post-workout recovery
- Chronic inflammation management
Heat Performance & Warm-Up Time
This is one area where Clearlight has both a pro and a con.
Warm-Up Time
- Takes ~20 minutes to reach ~140°F
- Does not heat as aggressively as some traditional saunas
Maximum Temperature
- Typically tops out around 140–155°F
For some users, this may seem low—but it’s actually intentional.
Why Lower Heat Can Be a Good Thing
The reviewer makes an important point most sauna buyers overlook:
Excessive heat (175°F+) can:
- Stress the brain
- Increase risk of brain swelling
- Negatively affect testicular health in men
From a longevity and recovery standpoint:
- 140–150°F is more than sufficient
- Infrared heat penetrates deeper than traditional saunas
So while slower warm-up is a downside, the lower max temperature may actually be safer long-term.
Downsides of the Clearlight Sauna
No product is perfect. Here are the real drawbacks.
1️⃣ Speaker Quality
- Built-in speakers are mediocre
- Not high-end audio
- Most users will prefer external speakers or headphones
2️⃣ Warm-Up Time
- Slower than some saunas
- Requires planning ahead
Neither of these are deal-breakers—but they’re worth knowing.
Size & Comfort
The Sanctuary 1:
- Fits one person comfortably
- Can fit two smaller people if cozy
Clearlight also offers:
- Sanctuary 2 (two-person)
- Sanctuary 3 (three-person)
- Larger family-sized models
So scaling up is easy if needed.
Pairing With Red Light Therapy
One recommendation from the review:
- Use red light therapy in the morning
- Use the sauna post-workout or later in the day
This combination supports:
- Mitochondrial health
- Recovery
- Circulation
- Hormonal balance
