The following may not be a full list of contraindications but if you have any existing conditions, it is always recommended to consult with your healthcare professional before using the Recovery Systems Qi Mat. Organ Transplants Recipients of any type of organ transplant (kidney, heart, liver, etc.) should not use the Qi Mat. After an organ transplant, patients will be on immune suppression medications to prevent organ rejection. PEMFs may stimulate or activate a more aggressive rejection process by stimulating the immune system. External Pacemaker/ Cochlear Implants/ Intrathecal Pump Anyone who uses an implanted electrical devices like pacemakers, cochlear implants, intrathecal pumps, etc. should not use the Qi Mat. The magnetic field may interfere with the functions of the devices. Pregnancy/ Expectant Women Pregnant women should not use the Qi Mat. Newborn Babies/ Infants Newborns and infants should not use the Qi Mat.   Use with Caution Medications Anyone who is currently taking prescription medication should consult their healthcare professional before the use of the Qi Mat. The use of the Qi Mat's far infrared rays may interfere with certain medications or some medicines may impair the body's natural heat loss mechanism or cause the body to be more prone to heat stroke. Medical Treatments Anyone who is undergoing any medical treatments, radiation or chemotherapy should consult their healthcare professional before the use of the Qi Mat. Cardiovascular Diseases/ Hypertension/ Hypotension Anyone with cardiovascular disease, hypertension/ hypotension or other similar medical conditions should consult their healthcare professional before the use of the Qi Mat. Internal Pacemaker/ Defibrillator Anyone who uses an internal pacemaker and/or defibrillator should consult their healthcare professional before the use of the Qi Mat. In general, infrared heating pads have not been shown to interfere or damage pacemakers/defibrillators. However, there may be a small chance of causing interference occasionally. Use the Qi Mat with no heat and negative ions only. The use of the Qi Mat increases circulation of the blood, which can cause an increase in heartbeat. Some people who use a pacemaker, experience discomfort since their heart beat is being controlled. If you are experiencing continued discomfort, discontinue use immediately and seek medical attention. For persons with a defibrillator, do not lay the Qi Mat directly over your device. Fever Anyone experiencing a high fever should use the Qi Mat with no heat and negative ions only. Joint Injuries Anyone with fresh or recent wounds/ trauma or (acute) joint injuries should use the Qi Mat with no heat and negative ions only. Injuries should not be heated within the first 48 hours, as joints that are hot or swollen may respond poorly to heat. This is also to avoid exacerbating any inflammation. Insensitivity to Heat Anyone with diseases or conditions associated with a reduced ability to sweat or insensitivity to heat should use the Qi Mat with no heat and negative ions only.   Immobility/ Physical Disability Anyone with difficulty moving or changing positions while seated or in bed should use the Qi Mat with low heat only (35°C - 45°C) or with negative ions only, for no more than 8 hours per day. Persons with generally poor health or weakness, paralysis, injuries or illnesses that requires bed rest or wheelchair use, sedation, or coma are more at risk for bedsores (pressure sores) or possible low heat burn. Qi Mat should be used under the supervision of the guardians only. Certain Ailments Anyone with the following ailments should use the Qi Mat with no heat and negative ions only. It is advisable not to raise the core temperature for persons with the following conditions: Adrenal Suppression Disorders, Addison's Disease, Adrenal Insufficiency, Systematic Lupus Erythematosus, and Multiple Sclerosis (MS). Recent Medical Conditions Anyone with recent stroke, aortic stenosis, myocardial infarction, heart attack, unstable angina pectoris or other similar conditions should use the Qi Mat with no heat and negative ions only. Brain/ Other Tumor Anyone with a brain or other tumor should use the Qi Mat with no heat and negative ions only. Bypass Surgery Anyone who have undergone any bypass surgery should use the Qi Mat with no heat and negative ions only. Diabetics Anyone with diabetes should use the Qi Mat with no heat and negative ions only. Diabetics' skin is weak, which can cause low heat burn from the use of the Qi Mat. Once the skin is damaged, it may be difficult to recover. Surgical Implants Recipients of titanium, metal, ceramic, or plastic implants can use the Qi Mat. Surgical implants generally reflect infrared rays and does not perceptively interact with static magnets or PEFM. Safety precaution is not to lay with joint replacements in direct contact with the mat. Anyone who experiences discomfort or pain in implants areas should decrease the temperature and duration of the session, or use with no heat and negative ions only, turn off the PEFM function. However, some joint replacements and other metals may be warmed by infrared rays or react to PEMF, it is recommended that they consult their healthcare professional or implants manufacturer before the use of the Qi Mat.   Silicon Implants Silicon implants may be warmed by infrared rays. Silicon used in medical implants is known to melt at over 200 degrees Celsius / 392 Fahrenheit, so it should not be adversely affected by infrared rays. However, it is recommended that they consult their healthcare professional and implants manufacturer before the use of Qi Mat. Others It is not recommended to use any part of the heating area of the mat directly on your head. Our brains do not have the same efficient cooling system as other parts of body does. Use a pillow as a barrier between your head and the mat if you plan to sleep on it. If you use heating creams or balms, liniments, salves or ointments that contain heat-producing ingredients, you should not use them with the Qi Mat so as to avoid burns. Please consult your healthcare professional before the use of the Qi Mat. If you have any pre-existing or history of any conditions that may be cause for concern, consult your healthcare professional if the Qi Mat is suitable for you. Pain Pain should not be experienced when using the Qi Mat. However, the infrared heat will go to problem areas or discomfort areas so some people may perceive this as pain and others as a sensation. Stop using the mat if any pain is persistent; discontinue use. Worsen Condition Stop using the Qi Mat if any known conditions worsen while using. Do note that some temporary symptoms may occur, which can be attributed to the detoxification and healing process. For more information, please check our website www.recoverystyemssport.com. EMFs
