Far infrared sauna therapy (FIRT) works in many ways to help strengthen the immune system. The gentle heat from the far infrared sauna raises the internal body temperature which mimics the state of fever. This “fever" stimulates the body's immune system to produce white blood cells like neutrophils, lymphocytes, macrophages, eosinophils and basophils; our body's defensive army. This is a similar process that occurs when you take an antibiotic, but the infrared sauna boosts the immune system naturally without the dangers associated with antibiotic usage. At the same time, the far infrared sauna stimulates detoxification of the body, (see detoxification). Detoxification can be defined as "the process of reducing the build-up of various poisonous substances in the body". Because the far infrared sauna wavelength penetrates the entire surface of the body up to two inches, a thorough cleansing takes place. The far infrared heat opens the pores which then allows the toxins to be flushed out with perspiration. Every system in our body performs better when it is free of toxins including the digestive, endocrine, cardiovascular, lymphatic and immune systems. The CDC (Centers for Disease Control and Prevention) estimates that over 80% of all illnesses have environmental and lifestyle associated causes. We are now living in a culture of stress that is literally killing us.
When our adrenal and immune systems are worn down we become more susceptible to cold, flu, infections and other dis-eases. The soothing heat that surrounds you in the far infrared sauna allows a deep relaxed state while stress levels decrease. You can literally reset the ratio of stress/relaxation in your life. The blood vessels open; (vasodilation), the heart rate increases; (passive cardio), muscles relax, pain is reduced as endorphins are released. Regular far infrared sauna therapy promotes a normalizing of the body's hormones through this effect on the autonomic nervous system.
