Re: why do some people sweat a lot ?

The quantity of the perspiration (sweat) is a function of the quantity of the 
glands that a person has.This number of glands is geneticaly determined and is 
different from person to person!Some have more some have less.The 
functionality of this glands depends on the climate.So if one person have a 
lot of them and is in a hot climate, they may perspire a lot,but if this person 
goes to a cooler climate some of the glands may start "sleeping" so less 
perspiration. 
I am afraid that you can do nothing about it, only use the antiperspirants 
the way that they work,and find a product that is effective for you!
