Far Infrared Heat
What are the benefits of far-infrared heat?
Pain Relief
Far-infrared heat stimulates vasodilatation of peripheral blood vessels, bringing oxygen to joints and extremities, speeding the healing of sprains and strains, thus relieving pain and reducing the time it takes the human body to recover from an injury.
Reduces Stress and Fatigue
Far Infrared heat reduces stress by loosening the muscles and relaxing the body. The gentle warmth gives you an overall massaging effect, soothing jagged nerves and knotted muscles. You'll feel rejuvenated and renewed, restored in both body and mind.
Improves Blood Circulation
Far-infrared heat is absorbed by cells, causing a physical phenomenon called "resonance". Thus the cellular activities are instantly invigorated, resulting in a better blood circulation and an overall improved metabolism. The increased blood circulation, but not blood pressure, stimulates the tiny blood vessels in the skin to expand accommodating the increased blood flow.
Removes Harmful Toxins
When toxins are present, blood circulation is blocked and cellular energy is impaired. The body's immune system is inhibited, which makes it difficult to fight disease. When far-infrared heat is applied, the large water molecules in our bodies that contain toxic gases like sulphur dioxide, carbon dioxide, lead, mercury and chlorine vibrate and are broken down. The encapsulated toxic materials and gases are then purged from the body through the skin, during perspiration.
Improves Immune System
The infrared heat raises your inner body temperature, inducing an “artificial fever”. Fever is the body's natural mechanism to strengthen and accelerate the immune response, as seen in the case of infection. This enhanced immune system, combined with improved elimination of toxins and wastes, increases your overall health and resistance to disease.
Removes Toxins
Far Infrared Heat increases blood circulation and the lymphatic flow stimulating the sweat glands, releasing built-up toxins and waste. Daily sweating can help detoxify the body as it rids itself of an accumulation of potentially carcinogenic heavy metals (lead, mercury, nickel, cadmium) as well as alcohol, nicotine, sodium, sulfuric acid and cholesterol.
What is far infrared heat?
Infrared is a band of light that we perceive as heat. While we cannot see infrared heat, we can feel its effects. Infrared radiation, or radiant heat, represents over half of the energy emitted by the Sun and is divided into three segments: near, middle, and far. Infrared rays heat our body by a process called conversion. Through conversion, far infrared heat can penetrate organic substances such as the human body without heating the air in between. You may notice a similar effect on partly cloudy days: when a cloud obscures the sun, you suddenly feel cooler, but the air temperature around you has not had time to be affected. The cloud blocked the sun's infrared rays from penetrating your body. By using far infrared heat as opposed to traditional heating methods, you enable the heat to penetrate deeper into your body without the skin discomfort of heating pads, hot towels, and some pain relief gels/creams. However, less discomfort is just one of many benefits of far infrared heat therapy.
Studies have shown that far infrared waves can actually penetrate up to 2-3 inches deep into muscular tissue and ligaments. When far infrared heat penetrates through the skin into muscular tissue and ligaments, it transforms from light energy into heat energy. The thermal effect within the deep layers of tissues cause blood vessels in capillaries to dilate which improves blood circulation and promotes healing and wellness.
  
These pictures were taken while using the Therasage massage bed. Yellow indicates poor blood circulation before starting the treatment. The orange indicates better blood circulation after 30 minutes. The red indicates improved blood circulation after 60 minutes.
