“Our Blackstone Sauna is the best investment we have made in a long time.”


There are many studies linking the benefit of soft heat from the infrared sauna to improved heart functioning. The strongest studies are the ones showing significant lowering of blood pressure in most subjects. A significant
decrease in blood pressure, cardiac ejection resistance, and total peripheral resistance is demonstrated in virtually every heart patient in each study. While there is consequently a significant increase in heart rates, stroke volumes, cardiac outputs, and ejection fractions, infrared sauna sessions are shown to significantly improve vascular endothelial dysfunction.


Sitting in an infrared sauna at 60°C is proven to be safe in patients that have Chronic Systolic Heart Failure and also significantly improves their tolerance to exercise. I found one study discussing ejection fractions at rates of 9-44%. These patients sat in a hot bath (41°C) for 10 minutes, and then had a 15-minute infrared sauna session at 60°C. Heart rate increased significantly (p < 0.01) and remained higher for 30 minutes following the session. There was no change in the systolic blood pressure, but a significant decrease in the diastolic blood pressure (p < 0.05).

While infrared sauna use does not appear to result in improvement of left ventricle pumping after an operation, it does significantly lower the blood pressure helping the heart function more easily. Infrared sauna usage shows no change in short term effects of cardiac output and is determined to be safe for heart patients’ use.

Okay, let me debrief the above paragraph:

  • Infrared Saunas are SAFE for heart patients

  • Infrared Saunas are effective in decreasing blood pressure in heart patients

  • Infrared Saunas help improve a heart patient’s tolerance to exercise

  • Infrared Saunas help to increase and improve heart function.

An ancient Greek doctor named Parmenides stated, “Give me a chance to create fever and I will cure any disease” (Hancock, 2003). Cancer continues to be one of the top killers in modern society. Cures for cancer are rare, intrusive, and painful. Receiving a diagnosis of cancer can put any family into a tailspin of fear and apprehension for the future. Cancer foundations abundantly dot the number of organizations striving to find cures for virtually any diagnosed type of cancer.

Multiple therapies emerge seemingly daily. The three common major forms of therapy include chemotherapy (invasive, debilitating, frightening), radiation (the same), and surgery, along with a multitude of alternative therapies from shock therapy to photo therapy to nutritional supplements and herbal supplements, to help the body rid itself of malignant cells and tumors.

Holistic cancer treatments work on strengthening the entire immune system and killing off toxic cancer cells through such interventions as diet modifications, anti-cancer herbs, and nutritional supplements. Even positive mental imagery helps the cancer patient work toward eliminating the enemy within.

Sweat Out Cancer

One thing all modalities agree upon is that cancer cells cannot survive heat. Cancer cannot live in temperatures above 42°C (107.6°F). Infrared heat becomes a “hyperthermic” treatment that artificially raises the body temperature allowing the body to literally burn out cancer cells. Malignant cancer cells are more sensitive to heat than healthy cells. Hyperthermic treatment consists of heating the body either in the local area of the cancer cells or tumor, regional sections, or by treating the entire body. Short & Turner (1980) found that hyperthermic treatments were especially successful in killing cells that radiation or chemotherapy were previously unable to kill, thus making a combination of chemo, radiation, and hyperthermic therapy desirable.

Infrared waves penetrate the skin past the epidermis into the dermis (outer skin layer to inner skin layer) at depths of approximately 3/4 to 1/5” (inches) (6-8cm or 1.0-2.5mm) (ICNIRP, Health Physics, Dec 2006, Vol 91, Number 6). This deeper penetration of heat into the skin results in increased action of the cell structure releasing water and toxins. With the buildup of chemo chemicals in the system, this rapid warming and releasing of water molecules and toxins aids in a quicker reduction of chemicals in the body system.

What The Experts Are Saying

According to Vancouver naturopath Jim Chan, far-infrared therapy has the ability to break the protective rings around harmful molecules so the cancer cell can no longer survive.  At the same time, it also weakens the bonds between toxins and human tissues allowing the flushing of stored toxins out of the system faster and in greater quantities through sweating and excretion.  Cancer patients, on average, have a higher load of toxins than healthy individuals, making the importance of flushing toxins from the system doubly important.

Combining cancer treatment modalities appears to be the most effective way of treating cancer and helping increase patient survival rates.  Phi Natural Health International, LITD produced a book entitled Natural Cancer Treatment in which they describe numerous natural methods to aid in helping individuals attack cancer. 
As with all health professionals, this organization strongly advocates patients seek qualified, licensed medical professionals at the first sign or onset of any type of cancer, and not try to self-diagnose or treat cancer without those qualified sources.


The organization presents a variety of natural treatments to supplement the treatments already prescribed or administered to patients, to maximize the healing potential of specific treatment regimens.  They agree that there are substantial benefits to overheating cancer cells, concurring that cancerous cells are damaged or weakened by temperatures of 42-43°C, but that this overheating is harmless to active healthy cells.  They recommend gradual overheating from temperatures of 42-47°C over a period of several weeks or months.

Before embarking on such a treatment, the Phi group makes several cautions.  They recommend that blood sugar levels be monitored closely to control tumor growth in the event the temperatures of treatment are not quite high enough.  They also state, “Hyperthermia is said to be one of the safest, most efficacious and economical way of removing heavy metals and toxic chemicals from the body”.  They explain that although prolonged high temperatures can often be uncomfortable to patients, the Cancer cure Foundation reports that heating the core temperature produces excellent results.  The foundation cites Dr.  Paavo Airola’s, PhD, ND book How to Get Well, that hyperthermia gives cancer a “triple whammy” by:

  • Removing accumulations of stored toxic chemicals that cause cancer;

  • Improving circulation so that the tissues are both nourished with oxygen and flushed of acidic metabolic wastes

  • Weakening or even killing cancer cells that have a lower tolerance for heat than healthy cells.

Finally, this group recommends hyperthermia as a way of preventing cancer through having a healthy lifestyle and removing toxins on an ongoing basis.

Hospitals And Hyperthermic Cancer Treatment

Kaltsas (2007) describes a form of hyperthermia treatments practiced at Klinik St. George, a fully licensed hospital in Bad Aibling, Germany, outside of Munich. The clinic is set in the foothills of the Alps and treats about 5,000 cancer patients a year – half from Germany and half from all around the world.

The Klinik St. George starts patients with a standard cancer protocol of a week of detoxification and strengthening of the immune system through diet and herbal supplements. They follow this by two to three weeks of hyperthermia treatment and low-dose chemotherapy. A typical treatment would involve heating the body in temperatures above 37°C (98.6°F) for approximately 2-2.5 hours, followed by a cool down of about an hour and a half or until the body temperature returns to normal.

This regimen continues two or three times a week for up to three weeks depending on the type of cancer. The clinic watches vital signs and organ functions with specific concern given to heart, lung, kidney, and liver functions throughout all their treatments.

Doctors and researchers at Klinik St. George have found that there are three major ways that high temperatures kill cancer cells, while at the same time increasing the potential of alternative diet and supplemental cancer therapies:

  • The first is that heat increases the cellular metabolic rate by breaking down glucose to lactic acid to decrease pH to low levels putting the body into an acidic state called acidosis. Acidosis leads to hypoxemia, or low oxygen supply, which eventually deprives cancer cells of oxygen.

  • The second benefit from heat is that, with added glucose, a temporary state of hyperglycemia (high blood sugars) is induced, which chokes cancer cells from a fresh blood supply.

  • The third way heat works- in addition to increasing cell permeability- is by damaging the membranes surrounding cancer cells, making them more vulnerable to anti-cancer agents such as chemotherapy and radiation. Studies have shown that when exposed to high levels of heat, cancer cells die faster at a fraction of the usual doses of chemotherapy and radiation.

The Klinik St. George uses hyperthermia treatments for the following cancers:

  • Breast

  • Uterine

  • Pulmonary and hepatic tumors

  • Pancreatic

  • Neuro-endocrine

  • Stomach

  • Bowel and bladder

  • Ear, nose, and throat

  • Brain

  • Lymph node

  • Local lymphomas

  • Skin cancers

In addition to finding improved reaction to traditional therapies of chemotherapy and radiation, patients exposed to hyperthermic treatments have also noticed a marked lowering of pain resulting in a decrease of pain medications. The clinic recognizes that the killing of millions or billions of cancer cells leaves multiple toxins in the body that can be detrimental to the overall health of the patient.

Consequently, they recommend efficient elimination of toxins from the body through a variety of methods, with sweat being the optimal form of detoxification (Kaltsas, 2007). The Klinik St. George can be reached through:

European Society for Hyperthermic Oncology
Other Media, Experts And Association’s Views On Infrared Therapy


The International Commission on Non-Ionizing Radiation Protection (ICNIRP), 2006, asserts in their official statement, “The medical use of infrared radiation has a long history. It has been widely used in physical medicine for treatment of sports injuries, muscle aches, pain, and some chronic diseases. In recent years there has been an interest in the use of IR-A sources for hyperthermic treatment of cancers” (2006, pg. 633).

A recent health magazine, Alive, printed an excellent article on using infrared therapy in the treatment of cancer. You can find this document at:

Hancock, 2003, discusses the inability of cancer cells to survive in extreme heat. There are several naturopaths, medical doctors, physiotherapists, and other health professionals using infrared saunas to assist their patients in cancer recovery.

One naturopath working in Nanaimo has several patients who have experienced dramatic results and healing of their cancer-ridden sites after chemo and radiation, by using an infrared sauna on a daily basis. Additional benefits of using infrared heat for cancer patients include better pain relief, more restful sleep, improved circulation, and a boost to the body’s regenerative abilities. (Hamblin, 2004.)

Studies conducted in Sweden, Finland, and Japan note significant improvement for people suffering from symptoms of rheumatic disease when they use infrared saunas. Some of the studies demonstrated rapid improvement over a few sessions of use while others noted a longer regimen (approximately five months of use). All the studies stated that participants reported alleviated pain and improved joint mobility (Flickstein, 2007; Hannuksela & Ellahham, 2001; Biro, Masuda, Kihara, & Tei, 2003).
