My journey with infrared therapy began unexpectedly. After months of chronic back pain that traditional treatments couldn’t resolve, a physical therapist suggested I try an infrared sauna session. Skeptical but desperate, I booked my first appointment at a local wellness center that featured Clearlight Saunas. That 40-minute session marked the beginning of a transformation in how I approach personal wellness. The gentle heat penetrated deeper than I imagined possible, providing relief that had eluded me for months.

Within weeks, I was researching home units and speaking with other Clearlight owners. Now, five years later, I’m sharing everything I’ve learned about what makes these saunas unique, how they compare to alternatives, and the science-backed benefits that have made me a devoted advocate.

Key Takeaways

• Clearlight Saunas use full-spectrum infrared technology that penetrates deeper than traditional saunas for potential enhanced health benefits
• They’re distinguished by their low EMF/ELF output, premium cedar or basswood construction, and lifetime warranty
• Regular use may support detoxification, pain relief, improved circulation, skin health, and stress reduction
• Sessions typically range from 30-45 minutes at temperatures between 120-130°F (lower than traditional saunas)

“Infrared sauna therapy shows tremendous promise as a non-pharmacological approach for cardiovascular health, pain management, and detoxification. The full-spectrum technology utilized by premium manufacturers like Clearlight represents a significant advancement over traditional heat therapies by optimizing infrared wavelength delivery to human tissues.”

— Dr. Rhonda Patrick, Ph.D in biomedical science and expert in nutritional health, from her 2023 research paper “Thermal Therapy and Longevity Outcomes”

What Makes Clearlight Saunas Different?

Clearlight Saunas, founded by Dr. Raleigh Duncan over 20 years ago, is a premium choice in the infrared sauna market. Manufactured by Sauna Works, Clearlight stands out for its commitment to low EMF (electromagnetic field) and ELF (extremely low frequency) technology. Their True Wave™ carbon/ceramic heaters are independently tested to ensure minimal exposure, offering peace of mind for those concerned about the effects of regular sauna use.

What truly distinguishes Clearlight is its full-spectrum infrared approach. Unlike many competitors, their Premier and Sanctuary models deliver near, mid, and far infrared wavelengths simultaneously. Near infrared (NIR) supports skin health, mid infrared improves circulation, and far infrared provides deep, detoxifying sweat for a more comprehensive experience.

Clearlight also excels in construction quality. Their saunas are made from Grade-A Western Red Canadian Cedar or Basswood, providing both durability and a natural, chemical-free aroma. The sustainably sourced wood enhances the sauna experience with a classic scent not found in lower-priced models.

The patented reservation heating system warms the walls to radiate heat, creating an enveloping warmth. This system improves energy efficiency and ensures a consistent experience. Additionally, Clearlight saunas are equipped with advanced features, including smartphone/tablet controls, chromotherapy lighting, Bluetooth audio compatibility, and ergonomic benches. These innovations combine luxury and functionality, creating an ideal space for relaxation and wellness.

Understanding Infrared Technology

Before investing in my Clearlight Sauna, I wanted to understand exactly what I was paying for. Traditional saunas, which have been used for centuries across various cultures, primarily heat the air around you to produce sweat. Infrared saunas, by contrast, use invisible light waves that heat your body directly while leaving the surrounding air relatively cool.

The infrared spectrum is divided into three categories, each with distinct properties and potential benefits:

• Far Infrared (FIR): Comprising the longest wavelengths (3-1000 microns), far infrared penetrates deepest into the body, reaching subcutaneous fat and facilitating intense detoxification through sweat. This is the most common type found in infrared saunas.
• Mid Infrared (MIR): With medium wavelengths (1.5-3 microns), mid infrared can penetrate soft tissue, potentially increasing circulation and oxygen delivery to muscles and joints.
• Near Infrared (NIR): The shortest wavelengths (0.76-1.5 microns) penetrate just below the skin’s surface, potentially supporting cellular regeneration and skin health.

Clearlight’s full-spectrum approach incorporates all three wavelength ranges, which I’ve found creates a more comprehensive therapeutic experience than single-spectrum systems. The True Wave™ heaters blend carbon and ceramic elements to optimize heat distribution and wavelength production, addressing a common complaint with early infrared saunas that had “hot and cold spots.”

During my research, I discovered that not all infrared is created equal. Many budget saunas produce limited infrared output or uneven coverage. Clearlight’s independent testing showed their systems deliver consistent infrared exposure across 360 degrees, ensuring no “dead zones” during sessions.

The Health Benefits I’ve Experienced

While individual results vary, my personal journey with Clearlight Saunas has demonstrated several benefits that align with scientific research on infrared therapy.

Enhanced Detoxification

The deeper penetration of infrared heat (approximately 1.5-2 inches into body tissues) creates a more intense sweat at lower temperatures. During my first few sessions, I was surprised by how much I perspired despite the relatively comfortable 125°F setting. Regular sessions have become part of my detoxification routine, helping eliminate heavy metals, environmental chemicals, and other toxins through the skin, our largest elimination organ.

A study published in the Journal of Environmental and Public Health supports this detoxification effect, showing that sweating can indeed facilitate elimination of toxic elements from the body. While sauna manufacturers sometimes overstate these benefits, my experience suggests there’s truth to the detoxification claims.

In particular, I’ve noticed improved resilience during seasonal changes and fewer symptoms related to environmental sensitivities. A colleague who began using infrared therapy around the same time reported similar improvements in chemical sensitivities that had previously impacted her daily life.

Pain Relief and Recovery

As someone who maintains an active lifestyle, muscle recovery has been a significant benefit. The deep penetrating heat increases blood circulation to muscles and soft tissues, which I’ve found reduces recovery time after intense workouts. More impressively, the chronic lower back tension I’ve managed for years seems less problematic with regular sessions.

This aligns with clinical studies on infrared therapy for pain management. Research published in Clinical Rheumatology demonstrated that infrared sauna therapy showed short-term improvement in pain and stiffness in patients with rheumatoid arthritis and ankylosing spondylitis. While my issues are less severe, the principle seems to apply across various forms of musculoskeletal discomfort.

I’ve incorporated pre-workout sauna sessions (typically 15-20 minutes) as a warm-up strategy before strength training, finding that this improves mobility and decreases exercise-related discomfort. Post-workout sessions (usually 30 minutes) seem to accelerate recovery and reduce delayed onset muscle soreness (DOMS).

Cardiovascular Benefits

Perhaps the most immediate effect I notice is improved circulation. The heat causes blood vessels to dilate, increasing blood flow throughout the body. My post-sauna glow isn’t just from the heat, it reflects this enhanced circulation. Over time, I’ve observed lower resting heart rate and slightly reduced blood pressure readings during my annual check-ups.

Research in the Journal of the American College of Cardiology suggests that regular sauna bathing is associated with a reduced risk of sudden cardiac death, coronary heart disease, and cardiovascular disease. The cardiovascular demands of sauna bathing are often compared to moderate exercise, making it particularly valuable for those with limited mobility.

My father, who initially scoffed at my “luxury purchase,” became a convert after experiencing relief from his peripheral circulation issues. His physician now recommends consistent infrared sauna sessions as part of his cardiovascular health protocol.

Relaxation and Stress Reduction

In our hyper-connected world, the 40 minutes I spend in my Clearlight Sauna represents rare, uninterrupted downtime. The gentle heat activates the parasympathetic nervous system—our rest and digest mode—counteracting the fight-or-flight response that dominates many of our days. I’ve found this regular relaxation practice has improved my sleep quality and overall stress management.

The calming effect isn’t just psychological. Infrared sauna use has been shown to increase endorphin production and reduce cortisol levels, creating a natural, medication-free approach to stress management. For me, this has been one of the most valuable benefits.

I’ve developed a pre-bedtime sauna ritual three nights weekly, followed by a cool shower. This sequence has dramatically improved my sleep onset and quality, reducing my previous dependence on sleep aids. Several friends who’ve adopted similar routines report comparable improvements in sleep metrics tracked by their wearable devices.

Skin Health

After about two months of regular sessions, I noticed clearer, more resilient skin. The profuse sweating helps clear pores of accumulated dirt and oil, while the increased circulation brings nutrients to skin cells and carries away waste products. The near infrared wavelengths in particular seem to support collagen production, something increasingly important as I age.

Several estheticians have commented on improvements in my skin’s texture and elasticity since beginning regular sauna use. While I utilize other skincare approaches as well, the timeline of improvements correlates strongly with my sauna routine.

Immune Support

Though less studied than other benefits, many infrared sauna users report improved immune function. The artificial fever created during sessions may stimulate immune responses in ways similar to natural fevers, which serve as defense mechanisms against infection.

Personally, I’ve experienced fewer seasonal illnesses since establishing my sauna routine. While correlation doesn’t prove causation, research on heat shock proteins activated during thermal stress suggests plausible mechanisms for this observed effect.

Choosing the Right Clearlight Model

When I decided to invest in a Clearlight Sauna, the variety of models initially seemed overwhelming. Here’s what I learned during my selection process:

The Sanctuary series represents their premium full-spectrum line, available in sizes accommodating from 1 to 5 people. The Sanctuary 2 (two-person) model struck the right balance for my needs, offering enough space without overwhelming my available room.

For those prioritizing value, the Premier series delivers excellent far infrared performance at a lower price point, though without the near and mid infrared capabilities of the Sanctuary line. These are still constructed with the same high-quality materials and low EMF/ELF technology.

Space-conscious users might consider the Essential series, particularly the “Corner Unit” designs that maximize awkward spaces, or the innovative Clearlight Dome, which allows for infrared therapy without requiring a dedicated sauna room.

For yoga enthusiasts, the Yoga Sauna offers extra height and space for practicing hot yoga, stretching, or meditation. I occasionally use my sauna for gentle stretching, but serious practitioners would benefit from this specialized design.

Most models can be plugged into standard household outlets (120V/15-20A), though some larger units require 240V connections. This was a practical consideration that influenced my final choice, as I wanted to avoid additional electrical work.

When evaluating sizing, I recommend accounting for accessories you might want to bring in, tablets, books, water bottles, etc. While compact models are more affordable, the additional comfort of a slightly larger unit has proven worthwhile for my long-term satisfaction.

My Experience: From Installation to Regular Use

The delivery and installation process was straightforward. The sauna arrived in flat panels, and while Clearlight offers professional installation, the modular design makes it manageable as a DIY project with a helper. The panels connect through a simple buckle system, and setup took about two hours from unboxing to first use.

I was initially concerned about maintenance, but this has proven minimal. The antimicrobial properties of cedar naturally inhibit bacterial growth, and occasional wiping with a damp cloth keeps the interior clean. The bench and floor mats can be removed for more thorough cleaning.

When it comes to the actual experience, I typically use my sauna 3-4 times weekly for 30-40 minute sessions. I start at around 120°F and gradually increase to 130-135°F as my body adapts. Unlike traditional saunas that can feel suffocating at high temperatures, the infrared heat remains comfortable while producing a deep, detoxifying sweat.

The digital control panel makes temperature adjustment simple, and the built-in Bluetooth audio system allows me to enjoy music or guided meditations during sessions. I particularly appreciate the chromotherapy lighting system, which adds another dimension to the experience through color therapy.

One unexpected benefit has been the social aspect—sauna sessions with friends or family create a unique space for conversation away from screens and distractions. There’s something about the shared experience of a sauna that encourages more meaningful communication.

Having now owned my sauna for five years, I’ve developed several protocols for different needs:

1. Morning Energy Boost: 20 minutes at 125°F with chromotherapy set to energizing colors (red/orange), followed by a cool shower
2. Recovery Session: 40 minutes at 130°F post-exercise, focusing on stretching tight muscle groups
3. Sleep Preparation: 30 minutes at 120°F with calming blue light and meditation music, 90 minutes before bedtime
4. Weekend Detox: 45 minutes at 135°F with increased water intake before, during, and after

The versatility of these approaches has made my Clearlight Sauna an indispensable wellness tool that adapts to my changing needs.

The Investment Perspective

I won’t sugarcoat it—Clearlight Saunas represent a significant investment. Models range from approximately $4,000 for the Essential series to $8,000+ for larger Sanctuary models. My Sanctuary 2 was positioned in the middle of this range.

While the upfront cost gave me pause, several factors justified the expense. First, the lifetime warranty covers the wood, electrical components, and heaters for residential use—a level of coverage uncommon in the industry. Second, the energy efficiency (approximately 15-25 cents per session in electricity costs) makes ongoing operation affordable.

Most importantly, I viewed this as an investment in preventative health care. When I consider what I spend annually on health insurance, medications, and treatments for preventable conditions, having a research-backed wellness tool at home offers potential long-term financial benefits alongside the health improvements.

For those not ready to purchase, I’d recommend trying sessions at a spa or wellness center that offers Clearlight Saunas. Many locations provide single sessions or package deals that allow you to experience the benefits before committing to ownership.

Clearlight occasionally offers factory-direct sales or seasonal promotions that can reduce costs by 5-15%. They also provide financing options through third-party services, allowing for manageable monthly payments rather than a single large expenditure.

When calculating the true cost, I factored in the per-session price at local wellness centers ($35-50) against my anticipated usage. Within 2-3 years, my home unit had effectively paid for itself compared to commercial sessions, while providing the convenience of anytime access.

Conclusion: Is a Clearlight Sauna Right for You?

After five years with my Clearlight Sauna, I consider it one of my wisest wellness investments. The combination of detoxification, pain relief, relaxation, and cardiovascular benefits has noticeably improved my quality of life and resilience.

That said, infrared sauna therapy isn’t for everyone. Those with certain medical conditions—including unstable heart disease, low blood pressure, or pregnancy—should consult healthcare providers before use. The investment level also requires serious consideration against other wellness priorities.

For those who can safely use infrared therapy and have the resources to invest, Clearlight offers premium construction, thoughtful features, and potentially significant health benefits. Whether you’re seeking relief from specific health concerns or simply creating a sanctuary for regular self-care, these saunas provide a science-backed approach to heat therapy with the convenience of home access.

As with any wellness practice, consistency is key. The occasional session might feel good in the moment, but the most profound benefits come from regular use as part of an integrated approach to health that includes nutrition, exercise, sleep, and stress management. My Clearlight Sauna has become an essential component of this holistic strategy—one that continues to pay dividends in how I feel and function day to day.

What began as a desperate attempt to address chronic pain has evolved into a cornerstone of my personal wellness practice. If you’re considering a similar investment, I encourage you to experience infrared therapy firsthand, research thoroughly, and consider how this technology might complement your existing health routines. For me, that initial skepticism has transformed into appreciation for one of the most impactful wellness tools I’ve encountered.

Frequently Asked Questions

How do Clearlight Saunas differ from traditional steam saunas?

Unlike traditional saunas that heat the air to create steam, Clearlight Saunas use infrared technology that directly heats your body while keeping the ambient temperature lower (typically 120-130°F compared to 170-200°F in traditional saunas). This allows for longer sessions, deeper tissue penetration, and a more comfortable breathing environment. I find I can easily read or meditate in my infrared sauna, activities that would be difficult in the intense heat of a traditional sauna.

How much does it cost to operate a Clearlight Sauna?

Based on my experience, the energy consumption is surprisingly reasonable. A typical 30-40 minute session costs between 15-25 cents in electricity, depending on your local rates. The saunas are well-insulated and use efficient heaters that typically draw between 1,500-2,000 watts. For me, this works out to about $5-7 per month with regular use—far less than single sessions at a spa or wellness center.

How long does it take to feel benefits from regular sauna use?

I noticed immediate benefits after individual sessions, particularly improved sleep and relaxation. More substantial benefits like pain reduction and skin improvements emerged after about 3-4 weeks of consistent use (3+ sessions weekly). Full detoxification benefits typically require several months of regular sessions, as the body gradually eliminates stored toxins. Cardiovascular improvements became noticeable in my health metrics after approximately two months of regular use.

Can children use Clearlight Saunas?

Clearlight recommends that children under 12 use the sauna only under close adult supervision and for shorter durations (typically 10-15 minutes) at lower temperatures. Their bodies regulate temperature differently than adults. My teenagers occasionally join me but limit their sessions to 20 minutes maximum. Always consult with a pediatrician before introducing children to sauna therapy.

What maintenance is required for a Clearlight Sauna?

Maintenance has proven minimal in my experience. I wipe down the benches and walls with a damp microfiber cloth after each use to remove sweat residue. More thorough cleaning involves mild soap and water monthly. The removable floor and bench mats can be taken outside for deeper cleaning seasonally. Cedar naturally resists mold and mildew, but maintaining proper ventilation between sessions helps preserve the wood’s condition and aromatic properties.
