I can't say really. But it is more than 15 mins in my experience. I have not done it this summer yet. All I used was a small plastic seal ice pack maybe 4"x4"x1" or something. I move it around behind me. The key, I think is that it's against your skin with little or nothing between it and flesh (maybe your shirt). It is wicked cold at first, but in the strong heat, that's a relief. The great thing about direct contact is that you can continue to benefit from it even as the ice gets fairly melted, since anything close to your skin that is cool provides a kind of relief on the hottest days, like a cool glass of water touching the forehead. I also liked how the small brick was neat clean and portable, I just brought it inside, rinsed it, and threw it into the freezer again. I have done that at work too, for the ride back home later...
