"Infrared sauna use does significantly lower the blood pressure helping the heart function more easily"
There are many studies linking the benefit of soft heat from the infrared sauna to improved heart functioning. The strongest studies are the ones showing significant lowering of blood pressure in most subjects. A significant decrease in blood pressure, cardiac ejection resistance, and total peripheral resistance is demonstrated in virtually every heart patient and in each study. While there is consequently a significant increase in heart rates, stroke volumes, cardiac outputs, and ejection fractions, infrared sauna sessions are shown to significantly improve vascular endothelial dysfunction. Sitting in an infrared sauna at 60 degrees C is proven to be safe in patients that have Chronic Systolic Heart Failure and it also significantly improves their tolerance to exercise. I found one study discussing ejection fractions at rates of 944%. These patients sat in a hot bath 41 degrees C for 10 minutes, and then had a 15 minute infrared sauna session at 60 degrees C. Heart rate increased significantly (p < 0.01) and remained higher for 30 minutes following the session. There was no change in the systolic blood pressure, but a significant decrease in the diastolic blood pressure (p < 0.05). While infrared sauna use does not appear to result in improvement of left ventricle pumping after an operation, it does significantly lower the blood pressure helping the heart function more easily. Infrared sauna usage shows no change in short term effects of cardiac output and is determined to be safe for use of heart patients. Basically:
Infrared Saunas are SAFE for heart patients
Infrared Saunas are effective in decreasing blood pressure in heart patients
Infrared Saunas help improve a heart patient’s tolerance to exercise
Infrared Saunas help to increase and improve heart function
