Great question. When I reached out to CoolMitt about this very question, they said there's anecdotal evidence but no studies. Definitely something to keep an eye on moving forward. I wasn't sold on the device until I used it in the sauna and saw a remarkable drop in my heart rate. I realize you wouldn't want to cool off in the sauna because all of the benefits come from the adaptations your body makes in the heat. It just seemed to be the easiest way to test the claims. Thanks for the comment!
@@MovementProjectPT From what I can see, there is no blood flow restriction included in the device. In the original studies, blood flow restriction was an important aspect of the process. Also, simply cooling the hands (or also parts of the face and feet) requires consideration of timing in relation to activity. While cooling the hands delays the rise in body temperature at first, it is my understanding the research shows there is a rebound effect called Hunting Response or Cold-induced Vasodilation (CVID) that later causes body temperature to climb even higher than if cooling had not been done. It is the Hunting Response or Cold-induced Vasodialation (CVID) that makes using this procedure more complex. In effect, to determine if the cold hand immersion practice works depends upon the activity period length and timing of initiation. Too long of an activity and cooling the hand (especially with blood flow restriction not included) is counter productive because of an "overheating" rebound effect occurring later into the activity. Conversely, too short of an activity and the response to cooling of the body is not realized at the best time or not necessary. This is why the typical protocol is to cool the hand about 30 min. before and extended activity so the cooling process occurs before the start of the activity but early enough so that CVID will have the least impact (Note: there will still be an impact). Significant trial and error (per athlete) is likely needed to find the ideal cooling duration and timing to mitigate CVID delayed overheating effects. To test the impact of the device used in a sauna (for example), it is best to use it for prolonged periods (min. of 45-1+ hrs.) with AND without cooling your hands. In that way, you can better compare protocols to determine your body's reaction and optimize the timing of cooling for maximum results. Plus, you can determine the important impact and timing of the negative repercussions from CVID. The claims for the device, while accurate, do not appear to provide complete guidance on effective use or reflect limitations. This helps explain why you do not see marathon or Ironman distance athletes using this procedure. However, I can envision how an extreme short distance athlete or (especially) team sports might find some benefit if they fine-tuned the cooling duration versus the rebound higher body temperature increase known as CVID. At the same time, body temperature is less of an issue for short, intense activities. As a result, that puts the both the practicality and effectiveness in question much less the correct and most effective protocol. While cooling hands prolongs delay before body temperature increases, it is also my understanding there is a rebound heating effect that results in the body temperatures actually climbing higher than if the cooling of the hands had NOT been done.
@@joemoya9743 Perhaps I am ignorant in my response because I skimmed your long response, but CVID doesn’t occur with the coolmitt. Dr. Huberman discusses this on his podcast, explains to people in IG comments and other places that you can’t simply dunk your hands in really cold water. The object or surface used for cooling should not be so cold that it causes vasoconstriction, or the narrowing of blood vessels. The Coolmitt as described by Huberman cycles water past your palm in a temperature range that is cool enough to remove the overheating occurring in your internal organs but doesn’t cause CVID. Also, since your palms will warm any water if dipped in cool water, the heat tends to hand around your hands in the water yet, you need new cool water to come in contact with your palms so that’s why the design gets more complicated with a glove that has cool water cycling on and past your palms and removed as it heat is carried away. I hope I regurgitated all that from memory well enough and didn’t make an ass out of myself. However, you can get the info directly from the horses mouth if I have any technical inaccuracies.

you should have done the cool mit tests first
Love the reviews!
Interesting. Do you know of any study references that showed improved recovery or impact to recovery?
