A sauna blanket is a padded, zip-up envelope with far-infrared heating elements built into its lining. You lie inside it with your head outside. It folds away between sessions and runs on a standard household outlet, which is why it is the most common entry point into home heat therapy.
Why it matters when you are comparing products
A blanket heats your body but not a room, and your head stays in ambient air. That is a genuinely different experience from sitting in a heated cabin, not a smaller version of one.
