Meet the Tuning Dome Personal Heater: a foldable, portable sauna that uses far-infrared rays to penetrate deep into the skin and generate heat in your body. It does not burn your skin but relaxes your body, reduces stress, and alleviates annoying pains. Such a device can be used for skincare, pain core, and more.
Tuning Dome does not take a lot of space, so you can use it anywhere. More information is available here.
