Introduction

For thousands of years people of all cultures have indulged in the soothing warmth of sweat baths. The Romans are well-known for their elaborate baths. The wealthy of 200 B.C. India did not consider their mansion complete unless it included a bathhouse with a steam room. The Muslim Hamman, or bathhouse, with its domed, central steam chamber is still an integral part of life in Muslim countries. A derivation of the Hamman, the Turkish bath, has been popular in Europe for centuries.

How it works

Although often misunderstood as a symptom of disease, fever actually is a part of the body's natural healing response. Steam baths, sauna, and other heat-inducing treatments elicit similar healing responses in the body, and consequently are often called "artificial fevers".

Hippocrates, the founder of Western medicine more than two-thousand years ago said, "Give me the power to create a fever, and I shall cure any disease."

Although the artificial fever induced by sweat therapy does not have the comprehensive effect of real fever, it still produces a striking effect on a number of bodily processes.

Today, steam and sauna facilities are an integral part of the hydrotherapeutic offerings at European and American spas, and steam rooms and saunas are a common feature of health clubs and public pools. Yet, there is surprisingly little awareness of the wide ranging benefits of steam and sauna bathing. There is evidence that these sweat-inducing treatments stimulate the immune system, improve circulation, and help the body to purge itself of impurities.

There is evidence that artificial fever works as an immune system stimulant by increasing the number of white blood cells in the body. In a 1959-review of studies on the effects of heat treatments, Mayo Clinic researcher Dr. Wakim and colleagues cite findings indicating that the number of white blood cells in the blood increased by an average of 58% during artificially induced fever. Researchers also have found increases in the activity of the white blood cells during induced fever.

In addition, as in the case of bodily induced fever, the raised temperature during the artificial fever reduces the growth rate of most bacteria and viruses, giving the immune system time to mobilise its own forces. Indeed, many regular steam or sauna bathers have experienced that a good, long sweat bath at the early onset of a cold or flu can help ward off the disease before in manifests as actual symptoms.

Apart from the immune system-stimulating effects of sweat therapy, many thought it as one of the most effective and painless detoxifying treatments available.

Heat speeds up the chemical processes in the body, making steam and sauna bathing one of the simplest and most comfortable ways to rid the body of accumulated toxins. As the pores open up and the million of sweat glands start to excrete, the body rids itself of metabolic and other waste products. Sweat contains almost the same elements as urine, and for this reason, the skin is sometimes called the third kidney. It is estimated that as much as 30% of bodily wastes are eliminated by way of perspiration.

However, more than common metabolic waste products are secreted through the skin. Natural health practitioners often notice that when heavy smokers get a steam bath for a body wrap (where the body 'simmers' for up to 45 min. Under hot covers), they will leave a yellow residue on the towels. Reino Tarkianinen, President of Finlandia Sauna, reports that when the company replaces sauna benches from public baths, a thick, black layer of accumulated tar can be found underneath the benches.

In Finland, research is being done on the use of sweat therapy in the treatment of people who are chemically affected. The purifying effects of perspiration could also be behind claims that steam and sauna treatments can help cur or control such ailments as acne and arthritis.
