After testing hundreds of saunas, we found that almost all the saunas on the market had trouble distributing heat evenly. This is a critical issue because the therapeutic effects of saunas are based almost exclusively on their heating abilities. Some saunas failed because they only heat your upper body, but not your lower body, or vise-versa. We believed that creating our sauna with balanced Omni-directional Heating™ was extremely important so we can provide you with the most beneficial therapies possible. Our engineers worked to develop our advanced heating technologies to fix the problems that other sauna companies could not. Medical Saunas™ are the first and only saunas that can help you get every possible benefit from a sauna environment.
