I wonder if this is a case of over-engineering a solution. Does it have that much more of a positive effect compared to a lower tech solution (e.g., bag of ice)

I wonder if this is a case of over-engineering a solution. Does it have that much more of a positive effect compared to a lower tech solution (e.g., bag of ice). The machine costs $2500 retail.

- DenisM 18y agoMy understanding is that hands in cold water will lead to blood vessels contracting and thus the entire body not being cooled, just your hands being kinda cold. Their device keeps blood vessels expnaded thus inducing hypothermia. The diference is between chilling entire body and only your arms.
- 13ren 18y agoDo you know why this happens, or how they circumvent it? Is it because it is water (i.e. not air-cooled)? Or is it because the temperature differential is too great (i.e. dangerously so, according to the body)? A damp towel might overcome these issues - or wetting your hands and holding them in front of a fan, for evaporative cooling via fake sweat + fake breeze.
- khafra 18y agoI've got a ~$120 vest full of a gel that freezes at 50 degrees, so it's not painful to wear. I use it as A/C on my motorcycle here in Florida; but my marathon-running co-worker says he's seen people wearing them for a few hours before races, to lower their core temperature. Looks like it works, but it can be done cheaper.
