The brain constitutes only 3% of the body’s mass, but uses up 30% of the body’s energy. When the lights go out, we suffer! When the lights dim, so do we. When energy to this organ is inconsistent our entire system falters. Ever have a great thought to contribute at a meeting only to forget that idea when it’s your turn to contribute? Do you struggle to come up with that one word or name? These are symptoms of “brain fog”, which is a symptom of low energy to the brain. It’s not that you lack intelligence, it’s that access to knowledge fails when our brain are underpowered. Don’t worry too much though, most brain fog is preventable and reversible nutritionally.
Sauna therapy is a proven method for detoxification from chemical exposures. We are exposed to 50,000 new chemicals in modern life. Chemical pollution comes from pesticides in our food, air (both indoor and outdoor) and our water supply. Exposures accumulate through low doses via workplace, personal care products, cookware, baby bottles, water-bottles, plastic food storage, the plastic lids on your to-go coffee cup, thermal receipt paper, and your mold-resistant PVC shower curtains. Studies have shown that we all have numerous toxins in our bloodstreams.
We encourage our clients to objectively assess their living environment for exposures with the goal of eliminating as much of the incoming toxicants as possible. An excellent resource for learning about these issues is the Environmental Working Group.
Many organic molecules can be eliminated from the body as a result of heavy sweating. Sauna provides a method to detoxify the body in people who are too unhealthy to handle intense exercise.
We recommend Infrared saunas from Heavenly Heat because the construction is free of adhesives, varnish and laminated wood composites. The highest grade of white poplar is used to avoid volatile organic compounds found in other materials. Heavenly Heat produces several models of varying sizes and combinations of heating elements. Dr. Waters recommends the combination units with both the tradition ceramic and infrared heating elements. These combination units quickly pre-heat prior to use and provide the most therapeutic heat.
Sauna use improves cardiovascular health through reductions in blood pressure and improved blood flow, providing results comparable to vigorous exercise. Sauna is a safe and suitable therapy for individuals who may not be healthy enough for vigorous activity. The therapeutic benefits of sauna therapy are well documented in the scientific literature. For those interested in the scientific underpinnings of sauna therapy, we have included a list of references and summaries below.
Sauna therapy is proven to:
New users should follow the recommended sauna protocol below. Drink water prior to and during sessions. You may bring a wood bowl filled with ice, water, and a wash cloth for use during treatment. Wash cloth can be placed over the top of head or neck as needed.
The time used to warm up the sauna is a good time to warm up yourself. Exercising to the point of breaking a sweat prior to entering the sauna can reduce the mild heat stress. Exercise such as yoga can help to build body heat from the inside-out, but even walking or taking an extended hot shower can help to build internal heat.
Drink a full 8 oz. glass of water prior to entering the sauna. You may continue to drink water during your session, especially as you adapt to increasing exposure length.
Weeks 1 and 2 10 minutes at 110-125 degrees
Weeks 3 and 4 10-15 min at 125-135 degrees
Weeks 5 and 6 15-20 min at 130-150 degrees
Weeks 6 + 20 minutes at 140-160 degrees
Note: In early sessions you should not progress to the next level of treatment if your body does not begin to sweat within 10 minutes in the sauna. Continue treatment at the current level until the body is able to sweat before proceeding.
Remain seated and use a cool towel to cool off before standing. Open the sauna door and vent to allow the temperature to gradual normalize.
Upon exiting sauna, remain seated, relax and breathe normally. Use a towel to wipe sweat off prior to showering. Showering will remove any secreted toxins that accumulate on the skin during treatment.

This study on 129 advanced cases of chronic heart failure showed a significant reduction in death over 5 years of treatment in the treatment group. The treatment involved 5 days of supervised saunas in the first week followed by twice weekly treatments for the duration of the study. Sauna exposure was 15 minutes at 140 degrees F. Additional benefits included an increase in ventricular ejection fraction, decrease in heart size, improved endothelial function, and a reduction in ventricular arrhythmias.

This study tested the effect of thermal stress on healthy individuals in two age groups. A group of 12 young males with an average age of 22 were compared to 12 older males, average age 68. Participants lay supine in a 160 degrees F sauna for 30 minutes. After 10 minutes of heat exposure, skin temperature rose slightly higher in the younger group, heart rate increase by 21 bpm in young versus 11bpm in the old. No change in blood pressure occurred in the young, however a significant reduction of 15 and 10 mm Hg was observed in systolic and diastolic measures in the older group.

A study comparing inpatient vs outpatient treatment of physical therapy combined with a sauna program showed that 13 of 13 patients intensively focused on a combination of nutritional therapy, elimination of food contaminants in a controlled environment with clean air and water resulting in improvement in 100% of patients. Of the 41 outpatients following the same sauna program at home, 70% of patients saw reduction in toxic organic chemicals along with a clearance of symptoms.

The insulin sensitizing effects of aerobic exercise can be replicated with heat treatments of sauna or hot tub. These improvement result from increased expression of nitric oxide, a vasodilator, resulting in reduced blood pressure. Regular at home thermal therapy provides an alternative to exercise for patients too impaired for physical activity.

Sauna therapy is an effective treatment for diseases related to chemical sensitivities in BH4 deficient individuals. Sauna exposure increasing vascular shear stress and induces expression of heat shock proteins which restores BH4 levels similar to the effect resulting from exercise. These diseases include hypertension, vascular endothelial dysfuction, heart failure, multiple chemical sensitivies, chronic fatigue and fibromyalgia.

In this case study a patient suffering 20 years from chronically debilitating multisystem disorder resulting from low-level occupational exposure to solvents was able to use sauna therapy to eliminate chlorinated and aromatic hydrocarbons from their body. Treatment enabled the patient to discontinue of medication and the patient was able to return to work.

Sauna therapy on 25 individuals at risk for cardiovascular disease were compared to 10 healthy controls. The at risk group had slightly larger resting brachial arterial diameters but a 50 percent reduced percentage of flow mediated dilation (%FMD) in response to sauna at start of study as compared to healthy controls. Following 2 weeks of daily 140 degree, 15 minute saunas, the at risk group was able to increase their %FMD up to 75% of that seen in controls. This resulted in a subsequent 5 point average reduction in blood pressure at the end of the study.
