The article states the uses of infra-red Therapy for Cardiovascular health and other conditions and then ends with the blanket statement "pregnant women, people with heart diseases, and those who are sick should never undergo infrared therapy.", so which is it: Good for "Cardiovascular Health" or dangerous for Cardiovascular Health? You can't have it both ways, either it is or it isn't.
Why aren't more studies being done? Is it because Big Pharma will lose $$$$ when people won't need Blood Pressure Meds?
