How many sweat glands on the hand?

The palm has around 370 sweat glands per cm2 or around 3000 per in2. When we climb and all of them sprinkle at once then it creates the problem. Why do they do it to us? In our case we deal with so called emotional sweating that is stimulated by stress, anxiety, fear, and pain. They say that both eccrine and apocrine glands produce sweat as a reaction to adrenaline. Conclusions: a) by controlling our emotions we can control palm sweating and b) palm sweating should warn us about increased level of adrenalin in the system.
