I have heard of this before, and I believe it is to do with your levels of hydration. As you sweat your body looses water. As water levels decrease the sweat becomes more concentrated in an act to save water. This means that all the salts etc in sweat are now more concentrated on your skin. To solve this (or just improve it) try drinking much more water whilst jogging. Hope this helped =)
