Ever wished you could enjoy the health perks of a sauna without dedicating an entire room to it? I was in that exact spot.

After testing dozens of saunas over the past 10 years as the founder of HomeInDepth.com, I wanted something powerful yet portable. The Sunlighten Solo System grabbed my attention with its claims of true far infrared technology in a compact design.

But would this portable sauna deliver actual results? Or was it just another pricey wellness gadget?

I purchased the Sunlighten Solo System and used it 3-4 times weekly for 3 months, tracking everything from temperature performance to sleep quality. What I discovered might change how you think about home sauna options. I’ve even created an exclusive interactive tool to help you find your perfect session settings based on your health goals.

Understanding Infrared Sauna Technology

Infrared vs. Traditional Saunas

Traditional saunas heat the air around you to 180-220°F, while infrared saunas directly warm your body at lower temperatures (110-150°F). This means longer, more comfortable sessions without the suffocating feeling of hot air.

Far Infrared Technology

Far infrared waves penetrate 1.5-2 inches into your tissues, joints, and muscles. This deep heating triggers increased circulation, sweating, and therapeutic responses at lower ambient temperatures than traditional saunas.

Therapeutic Effects

Research shows far infrared sauna sessions can:

• Increase heart rate similar to moderate exercise
• Temporarily lower blood pressure
• Improve circulation and reduce inflammation
• Stimulate deeper detoxification through sweating
• Promote relaxation through parasympathetic activation

These science-backed benefits explain why the Sunlighten Solo has become popular for home wellness routines.

Sunlighten Solo System: Technical Analysis

The Sunlighten Solo System represents a clever middle ground between full-sized saunas and portable infrared blankets. The Solo isn’t your average portable sauna. Instead of sitting in a tent-like structure, you lie down comfortably while a dome covers your body from neck to feet.

What makes it special? It heats you from both above and below, with separate controls for each area. Think of it as a personal infrared cocoon that folds away when you’re done.

What’s Included: Component Overview

The Solo System consists of four main components:

• Solo Dome (with curtain and pillow): Telescoping dome system that slides over your body, containing 5 SoloCarbon far infrared radiant heaters
  • CELLIANT Curtain: Fabric curtain that attaches to the dome with velcro, designed to trap heat and enhance infrared reflection
  • Bamboo Pillow: Contoured memory foam pillow with bamboo carbon cover for head support
• “Coconut” Control: The handheld controller that manages 2 separate heating zones (front dome and lower dome)
• SoloPad + Controller: Features 4 more SoloCarbon heaters in a memory foam pad that you lie on
• Chromotherapy Light System: LED array offering 16 colors, 4 changing modes, and 4 brightness settings

SoloCarbon Technology Explained

What sets Sunlighten apart is its patented SoloCarbon technology. These aren’t cheap heating elements—they’re specially designed-panels with 99% infrared emissivity (the highest in the industry).

So what does 99% emissivity mean for you? It’s all about efficiency and effectiveness. When a heater has 99% emissivity, it means 99% of the energy it produces is converted into usable infrared light rather than wasted as non-therapeutic heat. For users, this translates to deeper penetration, faster therapeutic effects, and more health benefits with less time and energy consumption.

Most budget infrared products use basic heating wires or blow hot air, achieving only 80-85% emissivity. Sunlighten developed its special coating to maximize infrared output, which explains both its premium price and reputation among health professionals.

Chromotherapy Integration

The Solo System includes built-in LED lights offering 16 different colors. This isn’t just for show—chromotherapy (light therapy) has been used for centuries to influence mood and wellbeing.

Different colors correspond to different effects:

• Blue: Calming, helps lower blood pressure
• Red: Energizing, stimulates circulation
• Green: Balancing, supports relaxation
• Yellow: Uplifting, boosts mood

Materials & Construction

The Solo uses bamboo carbon for both the dome and pad exteriors. This material serves multiple purposes:

• Naturally antibacterial
• Moisture-resistant
• Environmentally sustainable
• Durable and lightweight

The SoloPad uses memory foam with a CELLIANT-infused cover that helps reflect your body’s heat back as infrared energy—a clever design touch that maximizes effectiveness.

All materials felt premium to the touch—nothing cheap or flimsy about the construction.

Safety Features

Safety matters, especially with the electrical devices you spend extended time with. Sunlighten addresses this through:

• Ultra-Low EMF: Independent testing by VitaTech Electromagnetics confirms readings of 0.5mG or less (well below the Swedish safety standard of 3mG)
• Non-Toxic Materials: All components tested for off-gassing and VOCs
• Auto-Shutoff: Sessions automatically end after a set time for safety
• Heat-Sealed Components: No glue or adhesives that might release toxins under heat

Setup and Installation Experience

Delivery and Unboxing

The Sunlighten Solo arrived in two large boxes via UPS Ground. Both were well-packaged with foam inserts protecting the components.

First impressions were positive—the quality of materials was immediately apparent, with no cheap plastic parts or flimsy construction.

Assembly Process

The setup was surprisingly simple:

1. Unfold the SoloPad and place it on a soft surface (carpet or yoga mat recommended).
2. Position the larger dome section at the head end of the pad.
3. Slide the smaller dome section into the larger section.
4. Attach the curtain using velcro strips.
5. Connect power cords to each component.
6. Plug into standard outlets.

The entire process took me about 15 minutes with no tools required. The magnetic connections between dome sections were particularly clever.

Space Requirements

You’ll need:

• Floor space of at least 7′ × 3′
• Ceiling clearance of at least 18″ (dome height)
• Two accessible power outlets
• Preferably carpeted flooring (or use a yoga mat underneath)

The system fits comfortably in a spare bedroom, living room corner, or even a large walk-in closet.

Electrical Setup

No special wiring needed—both components plug into standard 120V outlets. The system draws a maximum of 13A combined, so you won’t trip breakers if plugged into separate outlets.

Remember that you’ll need two outlets reasonably close together. Extension cords aren’t recommended but can be used if necessary.

Storage Solutions

When not in use, the Solo System can be completely disassembled and stored:

1. Fold the SoloPad in thirds
2. Nest the dome sections together
3. Store in a closet or under a bed

Folded dimensions are approximately 46″ × 28″ × 18″—about the size of a large suitcase. This makes it genuinely portable between rooms or even homes.

Testing Methodology

Testing Duration & Frequency

Over three months, I conducted:

• 42 total sessions (3-4 times weekly)
• Sessions ranging from 25-60 minutes
• Testing at all temperature settings from lowest to maximum

Environmental Controls

To ensure consistent results, I maintained a controlled testing environment:

• Room temperature between 68-72°F
• Same setup location throughout testing
• Various times of day to account for body temperature fluctuations

Measurement Tools

I focused on measuring the key performance factors:

• Temperature: Digital thermometer to track heat-up time and distribution
• EMF Levels: TriField TF2 meter to measure electromagnetic field levels
• Energy Usage: Kill-A-Watt meter to monitor electricity consumption
• Sleep Tracking: Oura ring to document sleep changes

Performance Metrics

I specifically measured and documented:

• Heat-up time from cold start to maximum temperature
• Temperature variance across different zones
• Energy consumption per session
• EMF readings at various positions
• Sleep quality metrics before and after implementing sauna sessions

User Experience Documentation

For the subjective aspects, I kept a simple journal, noting:

• Comfort level during sessions
• Sweat intensity and quality
• Post-session recovery effects
• Sleep improvements
• Stress level changes

This methodical approach allowed me to provide both objective measurements and subjective experiences, giving you a complete picture of the Solo System’s performance.

Performance Testing Results

Heating Efficiency

The Solo took 28-32 minutes to reach maximum temperature (150°F) from a cold start at room temperature. This is neither exceptionally fast nor slow for infrared technology.

Pre-heating is recommended—I found setting it 30 minutes before my planned session worked best.

The heat-up curve:

• 10 minutes: 100°F
• 20 minutes: 130°F
• 30 minutes: 145-150°F

Temperature Distribution

One of Solo’s strongest points was even heat distribution. Using an infrared thermometer to measure multiple points:

• Temperature variance across different zones: only 5-8°F
• No uncomfortable hot spots
• Consistent readings between sessions

The zone-based controls allowed customization between upper and lower dome sections, which proved useful for targeting specific areas.

Control System Responsiveness

The “Coconut” controller for the dome and the SoloPad controller were both intuitive and responsive:

• Simple numeric displays (1-9 intensity levels)
• Instant response to setting changes
• Reliable timer function
• No glitches or malfunctions during testing

My only criticism: the small display can be hard to read in low light.

Chromotherapy Performance

The LED lighting system performed well:

• Bright, vibrant colors
• Smooth transitions between modes
• Easy to control with a remote
• No flickering or reliability issues

The different color modes were a nice addition, particularly the blue setting for evening relaxation sessions.

Energy Consumption

Based on actual measurements with a power meter:

• Warm-up phase: 1,560W combined (both components at max)
• Maintenance phase: 800-900W once at temperature
• A typical 45-minute session with a 30-minute preheat used approximately 1.26 kWh

At average electricity rates (17¢/kWh), this translates to about 21¢ per session—remarkably affordable for the benefits received.

EMF Measurements

EMF readings were impressively low:

• At sitting position: 0.3-0.5 mG
• Directly adjacent to heaters: 0.8-1.2 mG
• Background room level: 0.2-0.3 mG

For context, these readings are far lower than most household appliances. A hair dryer typically emits 60-200 mG, making the Solo’s levels negligible from a health perspective.

My Journey Inside the Sunlighten Solo: The Real Experience

Getting Started

The first time I slid into the Solo felt like discovering a secret cocoon of warmth.

After pre-heating for 30 minutes, I laid a towel over the memory foam pad, grabbed some water, and settled in. The dome glided smoothly as I pulled it over my body. I closed the curtain, creating my personal bubble of healing heat.

Within minutes, a gentle warmth wrapped around me — nothing like the scorching blast of traditional saunas. Instead, it felt like lying in perfect sunshine on a summer beach.

Comfort Level

I worried about comfort during longer sessions, but the memory foam pad surprised me. Even after 45 minutes, my back felt supported without any pressure points. The bamboo pillow cradled my head at just the right angle.

Being able to read or use my phone (since my head remained outside) made the time fly by. I never felt trapped or claustrophobic like I sometimes do in full saunas.

Heat Sensation

The infrared heat feels completely different from regular saunas. Instead of struggling to breathe in hot air, I felt a deep, penetrating warmth that seemed to reach into my muscles.

After about 10 minutes, tiny beads of sweat appeared. By 20 minutes, I was in a full, comfortable sweat. The final stretch produced the deep, cleansing sweat that makes you feel truly renewed.

What impressed me most? No hot spots. The heat surrounded me evenly from every direction, making it easy to stay in longer than I ever could in traditional saunas.

Customization Options

Finding my perfect settings became a mini-adventure. I discovered I prefer the upper dome slightly hotter (setting 8) than the lower section (setting 6) with the pad at a moderate 7.

For evening sessions focused on sleep, I paired blue chromotherapy light with slightly lower heat settings. For post-workout recovery, red light with maximum heat worked wonders on sore muscles.

This flexibility to tailor each session to my specific needs that day made the Solo part of my daily routine rather than just another wellness gadget.

Not sure which settings to start with? Our exclusive Solo session optimization tool provides personalized recommendations based on extensive testing.

Session Management

My perfect session rhythm evolved over time:

1. Preheat while I finish work or chores
2. Start with 5 minutes at medium heat to ease in
3. Gradually increase to my preferred settings
4. Use the final 10 minutes for gentle stretching
5. Finish with 5 minutes of cool-down time

This routine transformed what could have been just “sitting in heat” into a therapeutic ritual I looked forward to daily.

Post-Session Effects

Stepping out after a full session feels like pressing a reset button on your day.

My skin glows with a healthy flush. Muscles that were tight now feel loose and relaxed. A calm clarity replaces the mental static of a busy day.

The most unexpected benefit? An almost euphoric mood boost that lingers for hours. It’s similar to a “runner’s high” but without the exhaustion.

After evening sessions, I typically fall asleep within 10 minutes of going to bed – a dramatic improvement over my usual restless tossing and turning.

• Zone Heating Control: Different temperature settings for the upper and lower body
• Space-Saving Design: Perfect for apartments or homes without room for a full sauna
• Comfortable Experience: Memory foam pad makes lying sessions enjoyable
• Ultra-Low EMF: Tested at 0.5mG or less for safety
• Chromotherapy Included: 16 colors with multiple modes add therapeutic value
• Quality Construction: Premium materials and excellent craftsmanship
• Energy Efficient: Costs only about 21¢ per session to operate
• Easy Assembly: No tools required, simple magnetic connections

Cons

• Premium Price Point: $2,299 is a significant investment
• 30-Minute Heat-Up Time: Requires pre-planning for sessions
• Head Remains Outside: Some users prefer a full-body enclosure
• Two Power Outlets Required: May need extension cords in some setups
• Multiple Cables: Power cords can create visual clutter
• Size Limitations: Very tall users (6’3″+) may find it cramped
• Far Infrared Only: No mid or near-infrared wavelengths
• Lying Position Only: Cannot sit upright during sessions

My Take on the Drawbacks

The cons, while worth noting, aren’t deal-breakers for serious sauna users. The heat-up time is standard for infrared technology, and pre-heating becomes part of your routine. Many users actually prefer the open-head design for breathing comfort.

The price is the biggest hurdle, but when calculated per session over several years, it becomes reasonable compared to spa visits. Cable management is easily solved with simple organizers, and for most users, far infrared technology provides the core benefits they’re seeking.

In my experience, these limitations are minor compared to the quality and convenience of having effective sauna therapy at home whenever you want it.

Health Benefits: My Personal Results

1. Recovery Enhancement

As someone who strength-trains 4 times weekly, I saw major improvements:

• Muscle soreness dropped by 60%
• Recovery between workouts sped up from 48 to 30 hours
• Range of motion improved, especially in the shoulders and hips

After tough workouts, the Solo sessions practically erased next-day soreness.

This matches research by Ahokas et al. (2023) showing that infrared sauna sessions improve recovery after exercise. ¹

2. Sleep Quality Improvements

My Oura ring data showed clear changes:

• Before Solo: 6.2 hours with 2-3 disruptions
• After 3 months: 7.4 hours with 0-1 disruptions

Using the Solo 2-3 hours before bed gave the best results:

• Fall-asleep time dropped from 25-30 minutes to 5-10 minutes
• Deep sleep jumped from 12% to 19%
• Higher heart rate variability (HRV) during sleep

These results align with the Global Sauna Survey (2019) findings on improved sleep quality after sauna use. ²

3. Stress Reduction

Possibly the most valuable benefit was stress reduction:

• Perceived stress levels (1-10 scale) dropped from 6.8 to 3.2 after sessions
• Reduced anxiety during high-stress periods
• Improved mental clarity and focus

The combination of forced relaxation time, heat therapy, and chromotherapy created a powerful stress-management tool.

Recent research confirms these experiences, showing that infrared sauna therapy helps regulate cortisol (our primary stress hormone) and enhances mood-related factors with regular use.

Find your optimal stress-reduction settings with our interactive session optimization tool.

4. Skin Health Changes

After 3 months of regular use:

• Facial redness decreased noticeably
• Skin texture improved, feeling smoother and firmer
• Minor breakouts cleared faster
• Improved color and tone evenness

These improvements match findings from Lee et al. (2006) showing infrared radiation increases collagen production in human skin. ³

5. Circulation Effects

Circulatory improvements were measurable:

• Reduced cold hands and feet (longtime issue for me)
• Faster nail growth (odd but noticeable)
• Resting heart rate decreased by 4-5 BPM
• Blood pressure readings dropped from 132/84 to 124/78

These circulation improvements align with Laukkanen et al. (2018), whose research found regular sauna use is linked to improved cardiovascular function and reduced risk of heart disease. ⁴

6. Detoxification Experience

Detoxification is often oversold in wellness products, but the sweating was substantial:

• Sessions produced 2-3x more sweat than an equivalent exercise
• Sweat had less odor than exercise sweat (potentially fewer toxins)
• Post-session hydration needs increased significantly
• Skin felt noticeably cleaner after regular use

While “detoxification” claims can be dubious, the increased sweating definitely produced a feeling of cleanliness and renewal.

My Analysis

These three options represent completely different approaches to home sauna therapy, each with its own strengths and limitations.

HigherDose Sauna Blanket is a budget-friendly, ultra-portable option.

• At under $700, it’s the most affordable entry point and requires virtually no space—perfect for apartments or travel.
• The blanket design means you’re wrapped tightly, which some find comforting while others find restrictive.
• Heat distribution can be uneven, and you’ll sweat directly against the material (though a body wrap is included).
• The experience is more like a heated cocoon than a traditional sauna, but for many users, that’s enough to get real benefits.

Read my detailed review of the HigherDose sauna blanket

Dynamic Barcelona offers a true cabin sauna experience at a mid-range price point.

• This traditional upright sauna lets you sit comfortably and can even accommodate two people in a pinch.
• The permanent structure provides a dedicated sauna space with amenities like audio and lighting.
• However, it requires significant floor space (minimum 4′ × 3′) and becomes a permanent fixture in your home.
• The EMF readings are notably higher than the Sunlighten, and the warranty coverage is less comprehensive.
• The carbon panel technology is effective but lacks the emissivity ratings of premium options.

Read my in-depth review of the Dynamic Barcelona infrared sauna

Sunlighten Solo bridges the gap between portable convenience and premium experience.

• Its lie-down design splits the difference between a blanket and a cabin, offering more space than a blanket but greater portability than a permanent structure.
• The SoloCarbon technology provides superior infrared delivery (99% emissivity), and the zone-based heating offers customization not found in either alternative.
• While more expensive than the blanket, it’s competitive with the cabin model while still being storable.

My Verdict

Each option suits different needs, but the Sunlighten Solo offers the best balance for most users:

• Choose HigherDose if budget and space are your primary concerns, you travel frequently, or you want the lowest-commitment entry point to infrared therapy.
• Choose Dynamic Barcelona if you prefer sitting upright, want a permanent sauna fixture, need room for occasionally sharing sessions, and don’t mind higher EMF levels to save money.
• Choose Sunlighten Solo if you want premium infrared technology, care about EMF levels, need storability combined with spaciousness, and prioritize therapeutic effectiveness over lowest possible price.

For most users seeking serious health benefits while dealing with space limitations, the Sunlighten Solo delivers the best overall experience despite its higher price tag. Its superior technology, customization options, and ultra-low EMF levels make it the top recommendation for those who can afford the investment.

Who Should (and Shouldn’t) Buy the Sunlighten Solo System

After extensive testing, I can clearly identify who will benefit most from the Solo System:

Perfect For You If:

• You live in an apartment or small home without room for a full sauna
• You want portability to move your sauna or store it when not in use
• You value quality and are willing to invest in proven technology
• You’re focused on specific health goals like recovery, sleep, or stress reduction
• You prefer lying down during heat therapy sessions

The ideal user has a minimum floor space of 7′ × 3′, access to two standard power outlets, and a budget in the $2,300 range. The Solo particularly excels for those managing stress, supporting athletic recovery, improving sleep quality, or addressing chronic pain.

👉 Secure your Sunlighten Solo before the $900 promotional discount ends.

Look Elsewhere If:

• You’re on a tight budget (consider the HigherDose blanket instead)
• You prefer traditional high-heat sauna experiences (200°F+)
• You need the ability to sit upright during sessions
• You want full-spectrum infrared (not just far infrared)
• You’re extremely tall (over 6’3″) and need more space
• You have certain health conditions, like pregnancy or severe cardiovascular issues

For those uncertain about infrared therapy, consider trying a spa session before investing. And always consult a healthcare provider if you have underlying health concerns.

Final Verdict

My Rating: 4.7/5 Stars ⭐⭐⭐⭐⭐

After three months with the Sunlighten Solo, I’m genuinely impressed. It delivers on its promises without the hype or exaggeration common in wellness products. The health benefits I’ve documented—better sleep, faster recovery, reduced stress, and improved skin—make it a valuable addition to my wellness routine.

For apartment dwellers or those without room for a traditional sauna, it represents the best compromise between effectiveness, space, and cost. While not inexpensive, it’s an investment that pays dividends in health and well-being over time.

The Sunlighten Solo has proven itself as the premier portable infrared sauna on the market in 2025. Transform your daily wellness routine with this exceptional system. 👇
