Excessive sweating in dry heat
My assumption is that if you're sweating excessively, you could also be suffering from a condition called hyperhidrosis. This is a condition whereby your hands and feet sweat excessively. I would suggest that you try looking into using a solution like an iontophoresis machine to be able to treat this condition. I too have suffered from sweaty hands for a long time, and after trying different options, I found that using an iontophoresis machine provided me with the best results.
