Infrared Sauna Benefits


Why is Sauna beneficial?

The high temperature of sauna causes vigorous sweating and increased heart rate, producing an effect similar to the physiological response elicited by moderate exercise. When core temperature and heart rate are elevated, the body is forced to work hard to bring system back to balance. After just a few minutes in the sauna, you begin to sweat, your blood vessels dilate, circulation improves, cardiovascular function and metabolism are boosted, endorphins are produced and your immune response is stimulated. We at Salt Spa – St. Augustine deliver more of these vital therapeutic  benefits than any other sauna on the market. The key is emissivity it is your body ability to absorb infrared energy allowing it to heal. Sunlighten sauna delivers 99% in other brands you only receive a fraction of infrared heat versus hot air. That is depriving you of healing you need and time you don’t have. A sauna session should be therapeutic and enjoyable, not unbearably hot. In our sauna you will feel a gentle heat that provides a perfect space to briefly escape, relax and align with our stress management goals. Enjoy a little time out to tune in and restore your innate, creativity, response- ability to connect more fully with our own authentic energy.


Sunlighten™ Infrared Sauna – The best for your body!


Detox from a Sunlighten™ sauna is 7 to 10 times greater than a conventional sauna. In a conventional sauna, the average person sweats out 3% toxins and 97% water. In a Sunlighten sauna, the average person sweats out 20% toxins and 80% water!


Relieve back, neck, and arthritis pain with infrared sauna heat therapy. Researchers studying HRP (Heat Responsive Pain) have observed remarkable therapeutic benefits from using continuous, low-level heat therapy for treating HRP conditions like lower back and upper body pain.


A 30-minute infrared sauna session can burn up to 200-600 calories! As the body works to cool itself while using an infrared sauna, there is a substantial increase in heart rate, cardiac output, and metabolic rate. Sunlighten’s infrared heat therapy raises core body temperature, causing passive cardiovascular conditioning. Your body’s natural response to infrared heat therapy is to increase circulation and sweat. Check out the results with a heart rate monitor and be amazed!


In 2005, our Solocarbon® heaters  that are part of our sauna were used in a clinical study with the University of Missouri Kansas City and were shown to lower blood pressure from three-weekly 30-minute sauna sessions. Repeated infrared treatment improves impaired blood vessel functions in patients with high blood pressure, diabetes and high cholesterol, making it an effective preventative treatment for arteriosclerosis.


Infrared muscle heating increases blood flow level, mimicking the effects of exercise. Body temperature elevation also produces an increase in blood flow. Infrared heat assists in resolution of inflammatory infiltrates, edema and exudates. The increased peripheral circulation provides the transport needed to help evacuate the edema, which can help end inflammation, decrease pain and speed healing.


Improve your skin’s appearance with regular use of a Sunlighten sauna. Open wounds heal quicker with reduced scarring. Infrared heat therapy helps acne, eczema, psoriasis, burns and any skin lesions or cuts. It also reduces wrinkles, making skin look firmer and improving skin tone elasticity. Regular use may also help reduce cellulite trapped beneath the skin, lessen the appearance of scars, and heal burns significantly.


The Solocarbon 3-in-1 is the only sauna heater on the market that can provide all three infrared wavelengths in one place.
The infrared spectrum consists of near (NIR), mid (MIR), and far (FIR) waves, each with distinct characteristics and frequency ranges.  It’s impossible to deliver these three peak wavelengths at one time from a single source. That’s why Sunlighten developed a unique technology that combines three heating elements in one sauna heater.

Near Infrared

Near infrared (NIR) is the shortest infrared wavelength and penetrates the skin’s surface more effectively than the other two. Scientific research shows that when delivered at the vital wavelength of 880nm without extreme heat or light, NIR promotes skin renewal, cell health, wound healing, and tissue growth.

NIR heaters consisting of high-wattage halogen bulbs at extremely high temperatures are not comfortable or beneficial. In order to make NIR heat safe for saunas, Sunlighten used NASA research to develop a patented LED array that provides NIR at a singular wavelength with minimal variability and virtually undetectable heat and light. LEDs are effective because they can trigger a natural photo-biochemical reaction (similar to how plants use chlorophyll to convert sunlight into plant tissue).

Mid Infrared
Mid infrared (MIR) is a longer wavelength that can penetrate deeper into the body’s soft tissue where inflammation occurs. MIR helps expand blood vessels and increases circulation, so more oxygen can reach injured areas of the body. This reduces pain and speeds the healing process.

Far Infrared
The longest wavelength, far infrared (FIR), reaches deepest into the body, where toxins are stored. By raising your core body temperature, FIR stimulates the sweat glands, resulting in a deep, detoxifying sweat that leaves you feeling revitalized. Plus, since sweating increases heart rate, cardiac output, and metabolic rate, you’re also burning calories.

Sunlighten already achieved the most effective far infrared heater with their highly emissive Solocarbon coating . They’ve applied that same coating to their polyimide panel and discovered that application makes it 99% emissive!  This is why Solocarbon panels are the only far infrared heaters clinically shown to raise core body temperature nearly 3° for the most detoxifying sweat, lower systolic and diastolic blood pressure and aid in weight loss. no other infrared saunas on the market have such a high emissivity.

Infrared sauna with acoustic resonance therapy(ART)

Sunlighten is the industry leader in medical saunas. Far infrared heat therapy is safe, beneficial and easy to use to help achieve optimal heath. Far infrared heat is deep penetrating and helps dilate and expand blood vessels, helping relieve muscles and heal tissue injuries while accelerating the production of compounds that the body needs to heal faster. The deep heating allows for greater sweating and more elimination of harmful toxins. Infrared heat is known to help relieve aches, stiffness, soreness and increase blood circulation, helps to develop human growth hormone and increases the white blood cell count for a stronger immune system, so your body can fight illness and disease faster. After a sauna session, you will feel revitalized and your energy levels will increase. Our room is equipped with a private shower for mid-session cool downs. Stepping into the sauna room will enlighten all of your senses. The sauna is equipped with chromotherapy (light therapy), sound therapy and aromatherapy. The sauna surrounds your body with soothing, relaxing heat waves and the acoustic resonance speakers surround you with harmonic energy. ART translates music into deeply soothing stress reducing mind/body musical massage. It’s like bathing in a liquid sound being in a sauna at the same time. Tune out the stress, worry and noise and tune in to a musical body/mind massage experience that relaxes, inspires and refreshes you.

What is A.R.T? Acoustic Resonance Therapy

Acoustic Resonance Therapy (A.R.T.) utilizes sound and vibration to promote healing and relaxation in the body. Feeling the music we hear can create physical, mental, emotional and spiritual harmony in the body by stimulating the sense of feeling and deep relaxation. We are not trying to bombard the body with high power low frequencies but gently massage  the body with frequency ranges that support the body and mind’s natural relaxation response for optimal health and well being. Our ultimate goal is to honor the natural intelligence of the body and mind and not overstimulate, to support acoustic resonance throughout the bones, muscles and joints of the body what integrative medicine finds most beneficial for human body.

Healing touch of music

Music has a universal power to beneficially impact the human body, mind and spirit. Simply listening to music provides one level of experience, feeling the music you simultaneously hear, resonate  through your entire body and mind creates a sensory integrative, enhanced relaxation and rejuvenation experience that our clients describe as is ” beyond words”.
