An infrared sauna is a modern wellness therapy that uses infrared light — invisible wavelengths of light that gently heat your body without significantly warming the surrounding air. Unlike traditional saunas that heat the air first, infrared saunas warm your body directly, allowing you to reach a therapeutic sweat at lower temperatures (typically around 120–140°F / 49–60°C). https://www.quantumwellnessusa.com/ir-sauna/
