What is far-infrared?

Far-infrared is like invisible heat that you can feel from things like a warm blanket or a hot cup of cocoa.

Imagine your favorite cozy blanket on a chilly night, it feels warm because it’s sending out heat waves, but you can’t see them. Far-infrared is kind of like those invisible heat waves, only they’re even more gentle and spread out. You might not notice them at first, but they're there, giving things a soft warmth.

How It Works

Think of the sun as a big, bright light that sends out visible light, the colors you see every day. But it also sends out other kinds of waves too, like infrared, which is like invisible heat. Far-infrared is the part of that heat that’s really soft and slow-moving. It's like the slow, gentle hug from a warm blanket instead of the quick zap of a flashlight.

Some things around you, like your body or a glowing heater, also send out far-infrared waves. That’s why you feel cozy when you’re near a fire or wearing a fleece jacket on a cold day!
