Just wondering say once a day jackin off can lead to excessive armpit sweating if it helps im a guy

i pretty much sweat (under my armpits only) EVERYDAY! even if its cold out or what not. My armpits just get really sweaty but they never really smell. I cant even wear longsleeve shirts to school because it would be soo bad! .. PLEASE help me i dont know how to prevent it … if you know any tricks with out buying anything please let me know …. also let me know some treatment like certain deoderant or anything you can buy to make it stop also . THANKS … PLEASE HELP! ..so embarassing

I have a hat, which is part of a work uniform. I wear it in hot environs and thus sweat profusely. It has developed a characteristic odor. I cannot wash it in the machine and do not want to send to the dry cleaners.

Febreeze and other perfumes are not high on my list because of a sensitivity to them, and I merely want to eliminate the odor, not replace it.

Any help will be graciously appreaciated.
