The Sudatonic System: Contraindications

Prescription Drugs: If you are using prescription drugs, check with your physician or pharmacist for possible changes in the drug's effect due to an interaction with infrared energy.

Certain Ailments: According to some authorities, it is considered inadvisable to raise the core temperature of someone with adrenal suppression, systemic lupus erythematosus, or multiple sclerosis.

Joint Problems: If a person has a recent (acute) joint injury, it should not be heated for the first 48 hours or until the hot and swollen symptoms subside. Joints that are chronically hot and swollen may respond poorly to vigorous heating of any kind. Vigorous heating is strictly contraindicated in cases of enclosed infections be they dental, in joints, or in any other tissues.

Pregnancy: In pregnancy or the suspicion of pregnancy, discontinuation of sauna use is recommended. Finnish women use traditional saunas that don't heat the body as deeply as an infrared sauna for only six to twelve minutes and reportedly leave at that time due to perceived discomfort. Their usage of traditional saunas at this low level of intensity is not linked to birth defects. Infrared sauna use may be two to three times more intense due to deep tissue penetration, and comparatively shorter two to six minute sessions hardly seem worth any minimal risk they may present.

Surgical Implants: Metal pins, rods, artificial joints, or any other surgical implants generally reflect infrared rays and are not heated by an infrared heat system. Nevertheless, a person should consult his or her surgeon before receiving such therapy. Certainly infrared therapy must be discontinued if a person experiences pain near any implants.

Silicone: Silicone does absorb infrared energy. Implanted silicone or silicone prostheses for nose or ear replacement may be warmed by infrared rays. Since silicone melts at over 200 degrees Celsius, it should not be adversely effected by an infrared heat system. However, it is still advised that a person checks with his or her surgeon, and possibly a representative of the product manufacturer, to be certain.

Menstruation: Heating of the low-back area of women during the menstrual period may temporarily increase menstrual flow. Once a woman is aware that this is occurring, she can choose to allow herself to experience this short-term effect without worry. Or she may simply avoid using an infrared heat source at that time in her cycle.

Hemorrhage: Hemophiliacs and anyone predisposed to hemorrhage should avoid infrared usage or any type of heating that would induce vasodilation that can lead to the tendency to bleed.

Worsened Condition: Should any condition worsen with the use of an infrared heat system, the use of the system should be discontinued.

Pain: Pain should not be experienced when using an infrared heat system. If one does, the use of radiant heat is clearly inappropriate for the person at that time.
