Yesterday, I didn't use one and I'd have to say that I handled today's equally bad heat much better overall. I've had one of these for years but only remember to drag it out after a few days of a severe heat wave have already passed.
I'm not promoting any particular retailer of the bandanas, the above link came up with an on line search but these bandans are available at other souces as well.
I used to work in a factory with someone who used a similar product during the summer months. I never tried one myself (it was provided for him by the company) by he swore by it. A bit more high-tech than ice in a sock but seems to me like it works on the same principle; cooling down the blood being pumped through the carotids.
