How to stop sweating?

Unfortunately you cant stop sweating, and Unfortunately those deodurants dont really work, best I can suggest if its embarassing is use a good smelling deoderant and maybe bring an extre shirt to school to change durring the day n was up with a damp cloth and soap in the bathroom in problem areas Like armpits or wherever u need.
sweating is natural and may even ease up what u get older but for now all you can really do is try to manage it as best you can.

I think the people with denser hair on their body have the sweating problm.if you also have body full of hairs then you should just remove hairs or cut them time to time. Otherwise consult a doctr.
