In a perfect world, everyone of us would smell like we just stepped out of the shower -- even after we've been out the whole day. But the reality is, our body produces a myriad of scents and sometimes these can manifest as embarrassing B.O., especially in warm, moist parts such as the feet, underarms, mouth and groin area. And that's when the stench problem strikes. Here, the solutions that will banish those less-than-pleasant smells and keep you fresh.

1. Feet

Sweat itself is actually odorless -- it is the bacteria on your skin that live off perspiration on our body that create the stale smell. These bacteria thrive in warm, moist places, and because the feet have a large number of sweat glands and are often encased in shoes, all those moisture and heat provide the perfect breeding environment for odor-producing bacteria.

Fresh Fix: Wash and dry your feet thoroughly when you bathe, and wear shoes made with natural, breathable material such as canvas or leather. If that doesn't help, try applying an antiperspirant and sprinkle foot powder in your shoes.

2. Underarms

Like the feet, your armpits make a potential thriving ground for bacteria. If your blouse is constantly soaked with perspiration, you may have hyperhidrosis, a condition that is associated with overactive sweat glands and is usually inherited. Excessive sweating can sometimes be the symptom of an underlying hormonal disorder, such as an overactive thyroid or low blood sugar levels, especially when accompanied by dizziness or weight loss.

Fresh Fix: Use a deodorant that also contains antiperspirant, which helps mask underarm odor and combat excessive sweating -- look for aluminum chloride in the ingredient, the main chemical which blocks the sweat ducts. It's most effective when you dry the area before applying. For the more serious cases of hyperhidrosis, you may need a prescription strength aluminum chloride solution. Injections of botulinum toxin A into the affected area can also help diminish sweating.
