A small study assessed the concentration of 120 toxic compounds in three body fluids, and found many toxic elements appeared to be preferentially excreted through sweat.

Foundational paper by the renowned authority on heavy metal detoxification and founder of the Klinghardt Academy.

Third-party test demonstrates that Sunlighten's SoloCarbon heating technology produces high quality infrared, designed to be nearly perfectly received by the human body.

A small investigation into the effects of repetitive, mild hyperthermia found support to the body's immune system.

This article explains how heating the body from inside can improve the immune system just like a fever can, reducing the incidences of cold and flu.

This small clinical trial found that traditional sauna bathing significantly increased white blood cell count in athletes.

Scientific evidence for the immune effect of core body temperature increase to replicate what a fever does for the body's immune system.

Clinical review explains how fever helps fight infections as it stimulates heat shock proteins that deter viruses and reduce cytokine proteins.

This clinical trial found that regular sauna use likely reduces the incidence of common colds.

This study concludes that far infrared increases collagen and elastin in skin and helps improve skin texture.

This clinical study concludes FIR therapy improves muscle recovery after intense training as compared to passive recovery methods.

A study of 19 adult volunteers found that a sauna session was similar to exercise for the heart.

This article explains that endothelial function improves with heart rate increase via several mechanisms offered by exercising. We connect the benefits of increased heart rate to a passive cardio workout produced in an infrared sauna.

A clinical study over three months found cardiovascular benefits and reduced waist circumference in people with type 2 diabetes with regular infrared sauna use.

Clinical study concludes the benefits of thermal vasodilation therapy through repeated sauna treatment improves endothelial function, especially for those with risk factors for atherosclerosis.

This clinical study found that far infrared heat temporarily lowers both systolic and diastolic blood pressure.

In today’s world, our bodies are constantly exposed to toxins from the food we eat, the air we breathe, skincare products, dental fillings, and even tap water.

Only the Healing Far Infrared Sauna has this patented ceramic far infrared generator technology.

An overview of the properties of each band of infrared. Near, medium and far.

Tests conducted by one of the world's leading manufacturers of high-performance scientific instruments for molecular and materials research determined Sunlighten's heating technologies have 99% emissivity. That means our IR heaters deliver almost 100% of the valuable therapeutic wavelengths, retaining nearly perfect wave quality.

Randomized, controlled, and rater-blinded trial revealed a significant difference in median reduction of inflammatory acne lesions.

A study of one type of red and near infrared LED delivery therapy found it effective in rejuvenating facial skin.

Based on the original NASA plant growth experiments in space, this study concludes that LED irradiation greatly enhances the natural wound healing process.

A third-party study found that mPulse full spectrum infrared saunas increase flexibility up to 3x, using a blend of mid and far infrared.

This clinical study concludes FIR therapy improves muscle recovery after intense training as compared to passive recovery methods.

This small, double-blind clinical trial conducted by The University of Wisconsin-Madison found that raising the core body temperature of depressed volunteers to The equivalent of a mild fever improved symptoms of major depression.
