A sauna comprising:

• a heater having a first heating element and a second heating element, the first heating element configured to generate heat using a first current and the second heating element configured to generate heat using a second current;
• an electromagnetic (EM) radiation reducing device configured to reduce electromagnetic emissions from the first heating element and the second heating element, the EM radiation reducing device having a first electromagnetic (EM) radiation reduction element positioned adjacent to a first side of the heater and a second EM radiation reduction element positioned adjacent to a second side of the heater, wherein the first EM radiation reduction element has an elliptical curvature and geometry based at least in part on the heater;
• and
• a sitting area positioned near the first side of the heater.
