i clicked on the link expecting that they actually cool the blood flow like this (only using more compact wrist device instead of whole glove as we aren't talking extra quick cooling of sweating athletes)

"The newest version of the device is a rigid plastic mitt, attached by a hose to what looks like a portable cooler. When Grahn sticks his hand in the airtight glove, the device creates a slight vacuum. The veins in the palm expand, drawing blood into the AVAs, where it is rapidly cooled by water circulating through the glove's plastic lining."
