Those Cryobooths certainly make for some cool Instagram pics, huh?  And that's not all! According to CryoHealth's website, "Clients report that the experience is invigorating and improves a variety of conditions such as psychological stress, insomnia, rheumatism, muscle and joint pain, and various skin conditions.*"

What's that asterisk for? The statements above have not been evaluated by the FDA, notes Derek's doctor's site, adding, "These products are not intended to diagnose, treat, cure or prevent any disease."

Cool.
