The pursuit of longevity and wellness has driven increasing interest in infrared saunas, with research supporting their benefits for cardiovascular health, immunity, and mental well-being. However, traditional saunas require significant space, making them impractical for many. The Sunlighten Solo System aims to bridge this gap: a portable infrared sauna designed to deliver a full-body experience without the bulk. After two months of testing, here’s an honest assessment of its performance, pros, and cons.
What Makes the Sunlighten Solo Different?
Sunlighten has been a leader in the infrared sauna space since 1998, holding 23 global patents for its technology. Their Solo System stands out due to its focus on high-quality infrared emissions. Unlike many competitors, Sunlighten’s SoloCarbon panels achieve near-perfect emissivity (99%), ensuring maximum absorption by the body. The company even offers a unique design—the mPulse Smart Sauna—that delivers four wavelengths (far, mid, near-infrared, and red light) from a single source.
The Solo System itself consists of two key components: the Solo Dome and the SoloPad. The dome features five digital heaters, while the pad adds four more, enveloping the body in infrared warmth. The materials used are non-toxic, addressing concerns about EMF exposure. The system arrives well-packaged, though its combined weight of nearly 60 pounds is substantial.
Testing the System: Sweat and Comfort
The Sunlighten Solo was tested over two months in a Brooklyn apartment, used on wood floors with a yoga mat underneath. The system heats quickly and efficiently, inducing significant sweating within minutes. The dome’s two heating zones allow for temperature adjustments, addressing variations in heat distribution. The optional chromotherapy feature (with 16 colors) adds a sensory dimension, with red and violet proving particularly effective for heat perception and relaxation.
The SoloPad enhances comfort and heat retention, though it can also be used independently for targeted therapy. The stain-resistant material minimizes sweat concerns, though diligent users may still prefer a protective cover.
The Pros: Effective Heat, Quality Materials, and Portability
The Sunlighten Solo delivers on its promise of a full-body infrared experience. The even distribution of heat rivals that of full-sized saunas, inducing profuse sweating for a thorough detox. The company’s commitment to non-toxic materials ensures peace of mind, while the system’s compact design makes it surprisingly portable. The separate heater controls allow for personalized sessions, adjusting temperature based on individual needs. The energy efficiency—requiring just 1,260W for the dome and 300W for the pads—is another plus.
The Cons: Size Limitations and Weight
The Solo System isn’t perfect. Larger individuals may find the dome restrictive, with parts of the body potentially extending beyond the edges. The combined weight of 60 pounds makes it less mobile for some users, though a permanent setup mitigates this issue. While the system doesn’t cover the head, this avoids potential heat damage to hair, a concern with traditional saunas.
Final Verdict
The Sunlighten Solo System is a premium portable infrared sauna that delivers on its core promise: effective heat therapy in a compact package. Its high-quality materials, customizable settings, and focus on non-toxic design make it a standout choice for those seeking a convenient and powerful wellness tool. While the price point ($2,699) is substantial, the benefits—including enhanced sweating, improved circulation, and peace of mind—justify the investment for serious users. The Solo System isn’t just a sauna; it’s an investment in long-term health and well-being.
