Far Infra Red Saunas - what are they and how do they work?
|- Decreasing Blood Pressure|
Far Infrared Saunas have been around for years, but only recently have become popular in North America. Japanese have been utilizing the Infrared Saunas for the past century and have enjoyed tremendous health benefits from them.
Infrared Saunas are unlike conventional saunas which pull sweat out of the body. Far Infrared energy penetrates up to 3 inches into the body and PUSHES sweat out of the body. As the body is heated from the inside out, it forces toxins under the skin out.
The temperature of a far infrared sauna is typically between 90۫ - 120۫ F versus a traditional sauna which operates between 180۫ -220۫ F. However, despite operating at a lower temperature, you will typically perspire far more in infrared saunas because the infrared energy penetrates your body at a much deeper level. Fat becomes water soluble at 100۫ F when it begins to dissolve, move through the blood and finally is removed from the body, resulting in weight loss. Toxins are also eliminated through your skin using lower, comfortable temperatures, for rapid detoxification.
Radiant heat is more effective than other heat because it warms you – not the surrounding air. A great example of infrared heat is the sun. The warmth of the heat on your skin you feel on a cold sunny day is far infrared energy. Far infrared waves vibrate at the same frequency as we do, which is why they are able to penetrate into the flesh and warm you up internally. When people use traditional saunas, they typically DO go from the hot environment of the sauna into a cold shower or for a swim, because they feel the need to cool off after the intense heat experience. This is not the case with an infrared sauna, as the body does not experience the heat shock associated with the 200 degree temperatures of a traditional sauna. Because of this, one can easily stay in an infrared sauna for 30 minutes or more without feeling the need to “get some air” or cool down with a shower.
Sunlight consists of visible, UV and infrared light. Human cells, when exposed to sunlight, have certain chemical reactions. For example, when you are exposed to UV, you produce Vitamin D. A more recently discovered reaction is the affect of near-infrared light. When cells are exposed to certain wavelengths of near-infrared light, the mitochondria produces more energy, or adenosine triphosphate (ATP). This ATP is what powers every muscle in your body. If you exercise while exposed to near-infrared, you increase metabolism and burn more calories while having increased energy.
Far Infrared Saunas are a healthy weight loss solution without exercising. Infrared saunas can burn 400-600 calories in just one 30 minute session. In the chart below is a summary of how many calories a 150 pound person normally burns in 30 minutes of exercise:
Vigorous Racquet Ball 510
Rowing (peak effort) 600
Swimming (crawl stroke)300
In a far infrared sauna, a moderately fit person can sweat one pound of sweat in 30 minute session, which is the equivalent of running 2-3 miles. While it is true that the weight of the water expelled in the sauna may be regained by re-hydrating with water – the calories lost with not, resulting in weight loss.
Is your body Over ACIDIC?
If you are unable to achieve weight loss or continually trying to lose that last 15 pounds you could be over acidic. Often times the body holds on to extra weight because it is toxic and in an acidic environment. When a system is too acid, the body produces more insulin than usual. The more insulin that is available, the higher chance the fat will be stored rather than burned as energy, making it difficult for weight loss. To protect itself the body will hold onto the weight. As the toxic chemicals are removed from the body when using a far infrared sauna, weight loss is inevitable.
Saunas tackle congestive heart failure, arteriosclerosis, and hypertension
(taken from the article :- Sweat your way to a healthier heart - and a better sex life - in four weeks or less by Jonathan V. Wright )
Chemical analysis showed greater amounts of a substance called nitric oxide syntheses in the endothelial (lining) cells of the aorta, as well as the coronary, carotid, and femoral arteries of the hamsters that got the real sauna treatments. The reason this finding is so important is that increased levels of nitric oxide syntheses will produce more nitric oxide. Nitric oxide dilates coronary arteries, helping to improve heart function. That's good news on it's own, but it gets even better.
More detailed analysis showed a 40-fold increase in nitric oxide syntheses in the endothelial cells of the aorta after just one week. After four weeks of treatment, the increase leveled off but steadied at 50 percent.
The researchers treated 20 congestive heart failure patients with far infrared sauna daily for two weeks. They were compared with 10 "control-group" individuals, matched for age, sex, and degree of heart failure (according to the widely accepted New York Heart Association (NYHA)'s classification system.
After just two weeks of far infrared treatment, 17 of 20 sauna-treated individuals had significant improvement in clinical symptoms. Their ultrasound evaluations and blood tests were also significantly better. None of the 10 control group individuals had any change.
Previously, the same researchers had studied 25 younger men (ages 31-45) with one or more "coronary risk factors," including diabetes, hypertension, high cholesterol, and smoking. They were compared with 10 healthy younger men (ages 27-43) who had none of these risk factors. Compared with the "normal" men, the men with risk factors had impaired blood vessel dilation. After just two weeks of daily far infrared sauna treatments, the risk-factor group had very significant improvements in blood vessel dilation. The researchers wrote that these results "suggest a therapeutic role for [far infrared] sauna therapy in patients with risk factors for arteriosclerosis."
Given the hamster-in-the-sauna results, it's very likely that the improved blood vessel dilation in the men with cardiovascular risk factors resulted from higher levels of nitric oxide syntheses.
Infrared also increases flexibility and can significantly reduce pain from bad joints or a bad back when exercising.
Far Infrared heat can assist in breaking down cellulite. Cellulite is a gel-like substance made up of fat, water and wastes which are trapped in pockets below the skin. Profuse sweating helps clear this form of unwanted debris from the body.There are other effects of far-infrared. In the sauna, there is a mild warming sensation, not a hot sensation, as this would increase fatigue. This mild soothing warmth stimulates nitric oxide to dilate the microcirculatory system, meaning more blood and oxygen flows to the muscles. The increased circulation will accelerate the body’s natural detoxification processes and will benefit the connective tissue in the subcutaneous layer, therefore, reducing cellulite. Because the heat penetration of infrared saunas is over twice that of conventional saunas and up to ten times the level of heat in these tissues an Infrared Sauna can be significantly more effective than a conventional sauna.
The Infrared Sauna System delivers the same infrared rays experienced in the traditional American Indian sweat lodge. The cleansing and purifying benefits attributed to the traditional sweat lodges in American Indian and Scandinavian cultures have long been known. Infrared heat is simply a form of energy that heats the object directly, without having to heat the air in between. The skin is our largest organ and is responsible for eliminating up to 30% of body wastes. Infrared heat causes toxins to be released from the cells and exit the body through the sweat glands without burdening the liver and kidneys.
Our bodies react to the increased heating through the natural cooling process of perspiring. Through the perspiration process, acid and waste residue like toxins, sodium, alcohol, nicotine, cholesterol and the potentially carcinogenic heavy metals are removed from the cells (especially zinc, lead, nickel, cadmium etc.). As the pores of our skin open and discharge waste products, the skin sheds any old skin cells, leaving it glowing and immaculately clean, with improved tone, elasticity, texture and color.
Studies have shown that the detoxification potential of a far infrared sauna is 3 times greater than a regular sauna. When analyzing the water content of sweat in a traditional hot air sauna it was 95-97%. Conversely the water content of sweat in a far infrared sauna is about 80-85%. The remaining 15-20% contains toxic substances such as lead, aluminum and fluoride.

Nitric oxide is not just the key to getting a strong erection it's the key to getting an erection in the first place! Many men are unaware of how vital this chemical is in terms of male libido and here we will look at it and how to top it up naturally...
Nitric oxide is the chemical, which is realized in response to messages from the brain, in blood vessels that lead to the penis. When the messages are received the chemical is realized and blood vessels expand allowing blood to flow into the penis and create an erection.
Many men, who think they lack testosterone, actually lack nitric oxide and its one of the commonest causes of low libido in men particularly, as they get older.
This chemical naturally declines with age but the good news is - you can top it up naturally.
Infrared saunas make it possible for people who cannot or do not exercise enough to achieve the effects of cardiovascular training. It also allows for more variety in any ongoing training program. Most important to understand is that just like any other type of exercise, infrared therapy for decreasing blood pressure is most effective with frequent use.
FROM THE AMERICAN HEART ASSOCIATION
“...Saunas — if not misused — pose no risk to healthy people. People with high blood pressure who have no symptoms should tolerate saunas well. The relaxing of the blood vessels associated with the heat is about the same as from a brisk walk. Any active symptoms such as chest pain or shortness of breath that would cause a person to avoid moderate exercise would also be a reason to avoid a hot tub or sauna.
INFRARED THERAPY FOR BLOOD PRESSURE
While in an infrared sauna, blood flow rises from a normal five to seven quarts a minute to as many as 13 quarts a minute, in line with a heart rate increase of 25 or more beats per minute. Because infrared rays penetrate the body over 1-1/2 inches, there is a deep heating effect in the muscle tissue and internal organs. The body responds to this heat with a hypothalamic- induced increase in both heart rate and blood pumping volume. This can create a beneficial heart stress much like a sought-after cardiovascular training and conditioning effect. Medical research has suggested that the use of an infrared sauna provides cardiovascular conditioning as the body tries to cool itself. Also, during use, the infrared heat causes your capillaries to expand and thereby improve blood flow.
BLOOD PRESSURE CASE STUDY
One study about decreasing blood pressure comes from an article by Dr. Jonathan Wright. He states that in a study done on hamsters and infrared saunas, the hamsters, after four weeks of daily sauna therapy, had "a significant increase in a substance called nitric oxide synthase around the aorta as well as the coronary, carotid, and femoral arteries... The reason this finding is so important is that increased levels of nitric oxide synthase will produce more nitric oxide. Nitric oxide dilates coronary arteries, helping to improve heart function." These same researchers also conducted studies on humans as well, with very promising results. They tested 20 men with congestive heart failure for two weeks with daily sauna therapy, and a control group of 10 men with the same symptoms who got no sauna therapy. 17 or the 20 men had significant improvement in their clinical symptoms, ultrasound results and blood tests. While the control group had no changes. Dr. Wright goes on to comment on this study, "Given the hamster-in-the-sauna results, it's very likely that the improved blood vessel dilation in the men with cardiovascular risk factors resulted from higher levels of nitric oxide synthase. Although none of the studies have measured it specifically, far infrared sauna therapy will very likely lower blood pressure for many individuals too. This theory makes sense, since the mechanism of action is the same as in congestive heart failure: An increase in nitric oxide dilates blood vessels and lowers blood pressure."
