Heat has long been used as a method of healing, detoxification, and restoration. Today, saunas have evolved from steamy cedar rooms to advanced infrared systems that offer more targeted benefits. Two of the most popular choices in the world of infrared therapy are far infrared and full spectrum saunas. While both use light waves to gently warm the body from within, the difference lies in the range of wavelengths, the depth of penetration, and the kind of effects users can expect.
At Altered States Wellness, we offer full spectrum infrared sauna sessions designed to help you relax, recover, and renew. Whether you're easing sore muscles or seeking a natural way to support your overall health, understanding the difference between far infrared and full spectrum can help you make the most informed choice for your wellness journey.
What Is Infrared Light and How Does It Work?
Infrared light is a form of electromagnetic radiation that is invisible to the human eye but felt as heat. Unlike traditional saunas that heat the air around you, infrared saunas use light waves to heat your body directly. This results in a gentler, more tolerable heat that penetrates deeper into tissues. Infrared is commonly divided into three categories based on wavelength: near, mid, and far. Each type interacts with the body in slightly different ways.
Far infrared saunas emit longer wavelengths that are particularly effective at reaching deep layers of tissue, often up to 1.5 inches beneath the skin. This can increase core body temperature, improve circulation, and support the body's natural detox pathways. Full spectrum saunas, on the other hand, incorporate all three types of infrared light: near, mid, and far. This combination allows for a broader range of therapeutic effects, from skin rejuvenation to deep muscle recovery.
Understanding Far Infrared Saunas
Far infrared saunas are typically what people think of when they hear "infrared sauna." They operate within the 15 to 1000 microns wavelength range, focusing on the deeper tissue layers. Users often report a profound sense of relaxation, improved sleep, and a noticeable reduction in pain and inflammation after consistent use.
Because far infrared waves penetrate deeply, they are especially useful for those dealing with chronic joint pain, fibromyalgia, or systemic inflammation. These saunas also stimulate the sweat glands more effectively than traditional saunas, helping the body release heavy metals and toxins. The experience is gentler in terms of temperature—usually around 120 to 140 degrees Fahrenheit—making it ideal for people who may not tolerate the higher heat of conventional options.
Far infrared therapy has been studied for its cardiovascular benefits, with some research suggesting improved endothelial function and lower blood pressure. The deep heating also promotes better oxygen flow and lymphatic drainage, supporting the immune system and speeding up recovery from physical exertion.
What Makes Full Spectrum Saunas Unique?
Full spectrum saunas deliver a broader range of infrared wavelengths, combining near (0.76 to 1.5 microns), mid (1.5 to 5.6 microns), and far (5.6 to 1000 microns) infrared light. Each band of light penetrates the body to different depths and serves a distinct function.
Near infrared is the most surface-level and is absorbed by the skin. It's known to stimulate collagen production, support wound healing, and enhance skin clarity. Mid-infrared reaches slightly deeper and is helpful for improving circulation and easing soft tissue stiffness. Far infrared, as discussed earlier, goes the deepest and is most effective for detoxification and deep muscle relaxation.
What makes full spectrum saunas stand out is the ability to address a wide range of wellness goals within a single session. Whether someone is looking to improve their skin health, speed up muscle repair, or reduce stress, the combination of wavelengths can deliver layered benefits. This versatility is especially appealing to those with complex health needs or who are seeking to maximize each session's potential.
Another benefit of full spectrum systems is the option to adjust the settings based on your personal wellness goals. Some units allow users to prioritize one type of wavelength over another, giving more control and personalization to each session.
Which One Is Right for You?
Choosing between far infrared and full spectrum comes down to what you're hoping to achieve. If your primary goal is deep detoxification, pain relief, or support for chronic inflammation, far infrared may be all you need. Its focused wavelengths deliver consistent and reliable results, especially for those looking to reduce physical stress or support long-term healing.
On the other hand, if you're interested in a more comprehensive experience that targets the skin, muscles, joints, and even mood regulation, full spectrum saunas offer greater range. They're a great option for active individuals, those managing both internal and external signs of stress, or anyone curious about biohacking their wellness routine.
Keep in mind that consistent use matters more than the type of infrared sauna you choose. Both options support the body's natural healing processes, and either can be a powerful addition to your wellness routine.
Additional Considerations: Safety, Comfort, and Environment
Both far infrared and full spectrum saunas are considered safe for regular use. The key is to stay hydrated, listen to your body, and ease into longer sessions gradually. It’s also worth paying attention to the materials used in the sauna—wood quality, low EMF emissions, and ease of temperature control can all affect comfort and safety.
Those sensitive to light or with certain skin conditions may prefer the gentler approach of far infrared. People recovering from injuries or working with a functional medicine practitioner may benefit more from the tailored options a full spectrum sauna provides.
Ambient elements also matter. A calm, clean environment, integrated chromotherapy lights, and soothing sound systems can enhance the overall therapeutic experience, turning your sauna session into a full-body reset.
Final Thoughts
Infrared therapy is not a trend—it’s a science-backed method of supporting physical, emotional, and energetic wellness. Both far infrared and full spectrum saunas offer meaningful benefits, and the best choice depends on your specific needs and how you feel during and after each session.
At Altered States Wellness, we believe in offering tools that restore balance and help you feel more at home in your body. Whether you start with a far infrared session or dive into the full spectrum experience, you're giving yourself the gift of intentional rest and renewal.
