Some people find that certain foods and beverages make them perspire more profusely than usual or cause an unpleasant body odor. Caffeinated drinks, alcoholic beverages, garlic and onions are among the most common culprits.
If you like to jump-start your day with a cup (or two) of coffee but don't like how much you're sweating, you've got a decision to make. The beverage's heat will raise your internal temperature and signal your body to start producing sweat, and the caffeine will send your central nervous system -- as well as your sweat glands -- into overdrive. Of course, you could switch to iced, decaf coffee and avoid the problem altogether [source: WebMD].
Avoiding certain foods can help control underarm sweat, too. When you eat spicy foods, like peppers that contain capsaicin, it sends signals to your sweat glands. And, because the glands think your body needs to cool off, they'll begin to produce sweat [source: Watson].
There are some foods, however, that can help control sweating. We'll share more about these natural remedies on the next page.
