I has a science question. I trying out doing more excersize. In one of my zumba classes a teacher sugested I try a wet towel on my head (before class) and then a wet scare around my neck during class.
I feel as my googlefu skills are failing because I can't find a reason why that helps. Anyone know what the science is? LifeHacker and a pretty dated StackScience blurb speculated it has to do with having just enough gold water (relative to the hot air neer your body) to somehow make kind of cool air zone. Somehow how I am...skeptical Cooling of your head makes sense (hair gets wet and you cold water on your head just feels really good in the summer) But I don't get why cold towel or scarf around your neck can help. ============================================================ FRIAM Applied Complexity Group listserv Meets Fridays 9a-11:30 at cafe at St. John's College to unsubscribe http://redfish.com/mailman/listinfo/friam_redfish.com FRIAM-COMIC http://friam-comic.blogspot.com/ by Dr. Strangelove |
Are you getting overheated during class? I would assume that your teacher is suggesting this as a way to help keep cool. Evaporative cooling is especially effective in dry climates like Santa Fe.

That could be as well! I've taken to wearing a wet neck cooling scarf (because 85-90 degree heat is pretty hot) I was curius why things like and why stuff like that help as well as they seem to for cooling down Durring class yeah it's just a saftey and compfort issue with 30 something people dancing in The Studio On Tue, Jul 17, 2018 at 9:00 PM, Gary Schiltz <[hidden email]> wrote:

AHA! googlefu skills worked better this time. Something to do with with the neck (for example) helps with body heat and the wraps let off cold water... I guess I just don't understand how something that small can help cool you down. So I just thought I'd ask what the science might be On Tue, Jul 17, 2018 at 9:00 PM, Gary Schiltz <[hidden email]> wrote:

If you really want to blow your mind, consider these mesh cooling towels: https://www.amazon.com/gp/product/B06Y4RW17N/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 When you've been wearing it for a while and it has warmed up, you take it off, give it a sharp "snap", and it's immediately cold again. I use one when the temperature is getting high in my (non-air-conditioned) house and it works a treat. —R On Tue, Jul 17, 2018 at 9:30 PM Gillian Densmore <[hidden email]> wrote:

Yes that's similar to the kind that I have in your right it works great! On Wed, Jul 18, 2018, 8:41 AM Robert Holmes <[hidden email]> wrote:

Preface: I am not a fan of email...in it's current form. I have some pretty good notions to why. I will respect the mods and leave it their.
However, Mr. Homes yes! that is part of wonderful sense of curiusity why they are so helpful and why you can get some to refresh some... A shirt made sense I thought (it's got a lot of it to it) But basically bit of swim suit material around my neck helping? oO So...just out of curiosity I thought: let me ask!

Gil - There is always a lot of blood flow between the heart and the
brain which passes through the neck, fairly close to the skin.
Among the many things blood does, is act as a working fluid to try
to help thermoregulate the body... passing hot blood near the
surface of the skin where evaporation of sweat is cooling the
skin... The neck would be an obvious place to apply extra
external cooling efficiently. As with a cool cloth on the head, I think there is a perception issue involved, meaning that when you are overheated, cooling the region of your body you associate with "self", likely *feels* better than say, cooling your feet or your glutes... provides quicker apparent relief. I'm aware of the type of fabric you speak of, but have never used or inspected any. I'm assuming it somehow manages to *both* hold enough water to not evaporate away immediately but at the same time, have enough surface area (microstructure) to allow for a lot of transpiration. Why "snapping" it abruptly works to (re)improve it's cooling potential isn't as obvious to me, I'm betting it has been written up many times in everything from the popular press to academic journals in material science... time to practice more Google-Fu? - Steve

AAAAAH Ok thanks steve! I (hope) I haven't been hiding trying different ways to get in shape. Just to make sure what the guides sugested (as I only have one scarf) to show a little early wich is just done anyway for a new club. and wet it with cold waterdrape over my head for a a little bit. Then re wet the scarf. I thought with long hair or something a bit of tap cool water in the hair and on my head may help in someway. The scarf around a neck trick is a oldish but helps. Some even look cool for example mine has a print of a nebula in purple. I have no idea wich one. though Alas hovering around 240 depending on the scale I ask, that's still a bit to go. I want to shoot for being and staying at 225-230 at least. On Thu, Jul 19, 2018, 6:08 PM Steven A Smith <[hidden email]> wrote:
