Sunlighten’s patented SoloCarbon® infrared heating technology offers an exceptional detoxification experience by clinically increasing core body temperature by three degrees. This allows for a deeper, more effective sweat at the cellular level, as the SoloCarbon infrared waves penetrate the skin and raise your core temperature to help eliminate toxins. In contrast, traditional methods merely heat the outer skin with hot air. This results in a pleasant experience of more productive sweating, rather than an uncomfortable and stifling heat that produces less effective perspiration.

Infrared sauna sessions elevate your heart rate and enhance circulation, mimicking a cardiovascular workout we refer to as “passive cardio.” During infrared sauna use, blood flow can increase significantly from a normal rate of 5-7 quarts per minute to as much as 13 quarts per minute. Since your heart is a muscle, regular use strengthens it. A more robust cardiovascular system enables capillaries to deliver greater amounts of oxygen to muscle cells. For individuals with injuries or conditions that limit their ability to engage in traditional cardio activities, Sunlighten saunas provide an effective alternative, offering essential cardio benefits that contribute to both healthspan and lifespan.

Heat alone can be highly beneficial for recovery and short-term pain relief. Infrared light works by warming the body from the inside out, enhancing blood flow and circulation. Healthy circulation is essential for effective healing, as red blood cells deliver oxygen and nutrients to injured or inflamed areas, supporting the formation of new blood vessels and tissue. The faster red and white blood cells reach the muscles, the more quickly they can repair and regenerate.

Photobiomodulation involves the use of invisible near-infrared (NIR) light (700–1,200 nanometers) and visible red light (620–750 nm) to energize cells. Studies have shown that different light wavelengths trigger different biological responses. NIR light, especially around 880 nm, penetrates the skin deeply and is effectively absorbed by fibroblast cells, which then boost collagen and elastin production. When used alongside red light at 660 nm, the effects are amplified. With consistent use, this process can lead to thicker, more youthful-looking skin, reduced fine lines, diminished scars, and improved skin regeneration, cellular health, and tissue development.

Sunlighten saunas offer a naturally relaxing experience paired with a deep, cleansing sweat that leaves you feeling rejuvenated after every session. Powered by advanced SoloCarbon® heating technology, these saunas deliver highly effective infrared heat—up to 99% efficient—surrounding you in gentle warmth that helps reduce stress, soothe sore muscles, and promote complete relaxation.

Your body has a natural defense system, and a fever is one of its key responses—raising your temperature to help strengthen the immune system. This rise in temperature signals white blood cells, lymphocytes, neutrophils, and interferons to take action against infection. Elevated heat can also stimulate heat shock proteins that inhibit viral replication and reduce inflammatory cytokines. The therapeutic practice of intentionally raising body temperature is known as hyperthermia. Sunlighten’s advanced infrared technology delivers clinically proven, high-quality infrared heat that can increase core body temperature by up to three degrees for effective therapeutic benefits.

Poor sleep can lead to increased inflammation, stronger food cravings, insulin resistance, weight gain, heart disease, weakened immunity, mental health challenges, faster aging, and slower muscle recovery. Infrared sauna therapy supports the body by boosting detoxification, improving circulation, and enhancing mitochondrial function—all of which help the body operate more efficiently and contribute to better, more restful sleep.

Recent research highlights that behavior change techniques are essential for effective weight management. Sunlighten saunas offer a soothing and enjoyable experience, using infrared light to warm the body from within rather than heating the surrounding air. Operating at a comfortable temperature range (110–130°F), they provide greater health benefits in a gentler environment compared to traditional saunas (180–210°F). Integrated chromotherapy lighting enhances the experience by promoting balance and relaxation. While you unwind—listening to music or watching a show—infrared therapy works at the cellular level to flush out toxins, boost circulation, stimulate metabolism, burn calories, and support a slimmer waistline.
