A Sauna treatment deep cleanses naturally, increasing the metabolic rate, thereby speeding up the elimination of the body's waste products via the lymphatic system. When combined with essential oils, a sauna will relax and clear the head, eliminate stress, ease muscle pain, lift the spirits and re-energise both body and mind.
Everything in the universe emits and absorbs certain wave energies. If we look at a graphic representation of the electro-magnetic spectrum, we see infrared waves are longer than those in the visible range. Although the wavelengths of far-infrared are too long for our eyes to perceive, we experience the energy as gentle, radiant heat.
At the molecular level, FIR (far-infrared radiation) exerts strong rotational and vibrational effects that are either biologically benign or, in certain processes, biologically beneficial. This healing ability stands in contrast to the damaging effects of short wavelengths, such as X-rays and gamma rays.
The molecular effects of FIR are actually measurable through IR spectroscopy, a method of analyzing the emission and absorption of infrared light that reveals changes in atoms and molecules caused by IR (infrared) energy. In health-care, these effects are being harnessed to promote healing.
Humans, like any other organisms, have a unique absorption spectrum and respond specifically to particular electromagnetic wavelengths (EMWs). German professor Fritz Hollwich, Ph.D., conducted a study in the 1970s showing that individuals who sat under cool-white fluorescent lighting had elevated levels of the stress hormones ACTH and cortisol.
There was no such stress response in individuals who sat under full-spectrum lights that simulated sunlight. (As a result of studies like this, fluorescent lights are legally banned in German hospitals and medical facilities.) Dr. Hollwich's study is one of many that have shown that light has stimulatory and regulatory effects on biological systems.
Solar light energy is transmitted to the brain by nerve endings in the skin. These energy impulses stimulate the hypothalamus and this has an important controlling effect on the production of neurochemicals.
Given that neurochemicals regulate processes such as blood pressure, immune response, sleep, mood, and so on, there is little doubt that we exacerbate a wide range of health problems by spending the greater part of our lives indoors under inadequate lighting conditions.
Far-infrared light penetrates beyond the skin level and is absorbed efficiently by cells below, whereas visible light is mostly bounced off the skin surface. Near-infrared is mostly absorbed at the skin level and raises the skin temperature. Far-infrared can penetrate up to 4 centimeters (1-1/2 inches), exciting the vibrational energy of molecules and resonating with cellular frequencies.
