“Horses sweat and people perspire, my dear,” who has not heard this well mannered refrain? Getting hot and then getting all sweaty, that sticky, prickly and often unsightly condition that signals overheating, excitement and sometimes fear. Many of us have an aversion to one of our body’s most natural and important functions, especially in public places. In the right circumstances, perhaps with the lights out, most of us would agree that sweating can be fun, and that we often feel pretty good afterwards. Whether we are exercising, working strenuously or perhaps just experiencing a particularly hot and humid day, our bodies perspire to cool us down. What is also happening is that we are cleaning our largest single organ; our skin, as our sweat carries away toxins and impurities.
Sweating is an essential physical process, as it regulates the critical internal temperature of our bodies at around 37C. The skin has greater complexity in its make-up than any other bodily organ save the brain. Composed of blood vessels, nerve endings, pigmentation and lymph vessels, oil glands, hair follicles, cells that waterproof and prevent entry to bacteria, and our many sweat glands. Our skin is so vital that death will occur within hours if its pores and sweat passages are smothered. We have 2.3 million sweat glands embedded in our skin and these are activated by heat sensitive nerve endings, which produce the chemical, acetycholine, as an alerting agent. However not all of them respond as the aprocine sweat glands, located in our pubic and arm pit areas, are activated only by emotional stimuli. They carry a faint scent whose purpose is believed to arouse the sex drive. Nevertheless, the eccrine sweat glands, by far the most abundant, respond to heat.
Heating up the body on purpose through saunas, hot springs and steam rooms has been with us for as long as we have had recorded history. Broaching most cultures from east to west, thermal therapy has a rich and varied past. The baths of Ancient Rome and their importance to the socialisation of that particular civilisation are well documented. Bathing rituals that involved heating up the body and causing the participants to perspire and then scrubbing and massaging the skin are deeply embedded in these cultures. I suspect that the origin of these rituals had something to do with how good you felt afterwards and that feeling great impacted positively on their health.

The Journal of American Medical Association states: “A moderately conditioned person can easily sweat off 500 grams in a sauna, consuming nearly 300 kcal, which is equivalent to running 2 to 3 miles”. The Infrared Thermal System might stimulate the consumption of energy equal to that expanded in a 6 to 9 mile run during only one single session of 30 minutes. The Infrared Thermal System can play a pivotal role in both weight control and cardiovascular conditioning.

Health Effects of PCBs
PCBs have been demonstrated to cause a variety of adverse health effects. PCBs have been shown to cause cancer in animals. PCBs have also been shown to cause a number of serious non-cancer health effects in animals, including effects on the immune system, reproductive system, nervous system, endocrine system and other health effects. Studies in humans provide supportive evidence for potential carcinogenic and non-carcinogenic effects of PCBs. The different health effects of PCBs may be interrelated, as alterations in one system may have significant implications for the other systems of the body. The potential health effects of PCB exposure are discussed in greater detail below.
EPA uses a weight-of-evidence approach in evaluating the potential carcinogenicity of environmental contaminants. EPA’s approach permits evaluation of the complete carcinogenicity database, and allows the results of individual studies to be viewed in the context of all of the other available studies. Studies in animals provide conclusive evidence that PCBs cause cancer. Studies in humans raise further concerns regarding the potential carcinogenicity of PCBs. Taken together, the data strongly suggest that PCBs are probable human carcinogens.
PCBs are one of the most widely studied environmental contaminants, and many studies in animals and human populations have been performed to assess the potential carcinogenicity of PCBs. EPA’s first assessment of PCB carcinogenicity was completed in 1987. At that time, data were limited to Aroclor 1260. In 1996, at the direction of Congress, EPA completed a reassessment of PCB carcinogenicity, titled “PCBs: Cancer Dose-Response Assessment and Application to Environmental Mixtures” [PDF]. In addition to Aroclor 1260, new studies provided data on Aroclors 1016, 1242, and 1254. EPA’s cancer reassessment reflected the Agency’s commitment to the use of the best science in evaluating health effects of PCBs. EPA’s cancer reassessment was peer reviewed by 15 experts on PCBs, including scientists from government, academia and industry. The peer reviewers agreed with EPA’s conclusion that PCBs are probable human carcinogens.
