Far-infrared light heats the body directly causing a rise in core temperature resulting in a deep, detoxifying sweat at the cellular level, where toxins reside.
One of the most compelling reasons to use an infrared sauna is the natural pain relief associated with its use. Infrared heat works by penetrating joints, muscles and tissues, increasing circulation and speeding oxygen flow. For years, doctors have recommended infrared saunas because of proven relief from sports injury, chronic fatigue syndrome, fibromyalgia, arthritis and other chronic pain conditions. In a NASA study with infrared heat, they determined that LED technology allows for deep penetration of tissue and increased cell growth from the inside. A 2003 study showed that use of infrared heat therapy helped the production of white blood cells to alleviate inflammation and reduce swelling, two key factors in easing bodily pain.
Infrared saunas have been designed to encourage a lifetime of use through the purest form of relaxation and stress-reduction. Cortisol–a “fight or flight” hormone produced by the body–increases with stress, raising heart rate & blood pressure and leading to the deposit of excess calories in the midsection. Scientific evidence shows that infrared therapy helps the body maintain healthy levels of cortisol. In fact, infrared saunas have been clinically shown to reduce both systolic and diastolic blood pressure with regular use. Through the use of cutting-edge, soothing heating technology, they deliver the most therapeutic infrared heat per square inch (up to 99% efficient) to help you relieve stress, ease muscles and fully relax.
Results from a 2009 study indicated that infrared saunas are beneficial for lowering weight and waist circumference in just a 3 month period. Another study showed that 30 minute infrared sauna sessions can burn upwards of 600 calories. As the body works to cool itself in our infrared saunas, there is a substantial increase in heart rate, cardiac output and metabolic rate, causing the body to burn more calories.
Individuals who are using prescription drugs should seek the advice of their personal physician or a pharmacist for possible changes in the drugs' effects when the body is exposed to far infrared waves or elevated body temperature. Diuretics, barbiturates, and beta-blockers may impair the body's natural heat loss mechanisms. Some over-the-counter drugs such as antihistamines may also cause the body to be more prone to heat stroke.
Individuals with cardiovascular conditions or problems (hypertension, hypotension, congestive heart failure, or impaired coronary circulation) or those who are taking medications which might affect blood pressure should exercise extreme caution when exposed to prolonged heat. Heat stress increases cardiac output and blood flow due to the body's effort to transfer internal body heat to the outside environment via the skin (perspiration) and respiratory system. This takes place primarily due to major changes in the heart rate, which has the potential to increase by 30 beats per minute for each degree of increase in core body temperature.
The use of infrared should be avoided by anyone who is predisposed to bleeding.
Heating of the lower back area of women during the menstrual period may temporarily increase their menstrual flow. Some women endure this process to gain the pain relief commonly associated with their cycle, whereas others simply choose to avoid sauna use during that time of the month.
If you have a recent acute joint injury, it should not be heated for the first 48 hours after an injury or until the hot and swollen symptoms subside. If you have a joint or joints that are chronically hot and swollen, these joints may respond poorly to vigorous heating of any kind.
Metal pins, rods, artificial joints, or any other surgical implants generally reflect far infrared waves and thus are not heated by this system. Nevertheless, you should consult your surgeon prior to using an infrared sauna. Certainly the usage of an infrared sauna must be discontinued if you experience pain near any such implants. Silicone does absorb far infrared energy. Implanted silicone or silicone prostheses for nose or ear replacement may be warmed by the far infrared waves. Since silicone melts at over 200°C (392°F), it should not be adversely affected by the usage of an infrared sauna. It is still advised that you check with your surgeon and possibly a representative from the implant manufacturer to be certain.
Pregnant women should consult a physician before using a sauna because fetal damage can occur with a certain elevated body temperature.
