2. Infrared heater - Wikipedia

   en.wikipedia.org/wiki/Infrared_heater

   This makes a careful selection of the right infrared heater type important for energy efficiency in the heating process. [21] Ceramic elements operate in the temperature of 300 to 700 °C (570 to 1,290 °F) producing infrared wavelengths in the 2 to 10 μm range. Most plastics and many other materials absorb infrared best in this range, which ...

   Keeping flammable materials, such as paper, plastics, curtains, furniture, and bedding, at least 3 feet (0.91 m) away from the heater. Turning off the heater when the last adult leaves the room or goes to sleep and keeping children and pets three feet away from the heater. Placing heaters on a flat, hard, nonflammable surface.

4. Infrared sauna - Wikipedia

   A 2018 systematic review and meta-analysis of nine clinical trials found that five weekly conventional sauna sessions for 2 to 4 weeks was associated with a significant reduction in brain natriuretic peptide (BNP; a marker of heart failure progression) and cardiothoracic ratio (an indicator of heart enlargement), and improved left-ventricular ...

5. Infrared lamp - Wikipedia

   en.wikipedia.org/wiki/Infrared_lamp

   Infrared heating uses infrared lamps, commonly called heat lamps, to transmit infrared radiation to the body that is being heated. When a body with a large surface area needs to be heated, an array of infrared lamps is often used. The lamp commonly contains an incandescent bulb that produces infrared radiation.
