Your sweat-stained top and the pungent odor wafting from your armpits are immediate reminders of the rising mercury levels. Underarm odor is a major turn-off. It is not like your sweat smells any better during winters, but summers are definitely the worst. And no matter how much you shower, it just seems futile. Although deodorants help to a large extent and make you stink less throughout the day, using them is not a permanent solution. If you are looking for natural alternatives as opposed to chemical-based deodorants and want to achieve long-term results, this article is just what you need. Scroll down!

What Causes Underarm Odor?

Underarm odor, like body odor, is mainly linked to the apocrine glands.

These glands are often found in the genital area, nipples, armpits, breasts, and ears. While they are responsible for the secretion of milk in the breasts and earwax in the ears, they help in the secretion of sweat in your genital area, nipples, and underarms.
It is the sweat produced by these glands that produces odor. This odor, which may sometimes be foul-smelling, is a result of bacteria breaking down the protein-rich sweat.

Underarm odor is also noticed in children, who usually don’t develop foul-smelling body odor. But when they do, it might be due to certain factors or an underlying medical condition. The factors that lead to the development of body odor in children are:

  • Precocious puberty
  • Fish Odor Syndrome
  • Synthetic clothing
  • More sweat glands
  • Diet that consists of smelly foods like onions
  • Medical conditions like diabetes, phenylketonuria, and hyperhidrosis.

Whatever the cause of your smelly underarms may be, you can get rid of the problem by following the simple home remedies discussed below.
