I’m not sure what you mean by “sweating excessively” but if it is excessive then this may be due to the fact that your body temperature is too high. This can lead to other problems, such as muscle pain and irritation, so take care of yourself first before you worry about any hiccups in your sweat ranching.
Let’s say for example that during a hot hour you are sweating somewhat less than usual after an hour or two. You might try drinking some water or taking another drink to bring down your body temperature even further because that could stop the sweating completely until it cools down again later on. Whatever works for you!
