This is also said to control the body pressure levels to a maximum extent, as Indian women tend to work hard, more than her male counterpart. The most important thing to note about this Thirumangalyam is, that it should always be hidden or covered in the inner garments. Just because of the constant friction of the metal gold touching the body portion directly, the effect will be more to gain the said benefits. However, if the same is worn outside the clothes and making it visible to everyone, then the effect is reduced. That's why it is always advisable to wear the Thirumangalyam known as Thali or Mangalsutra inside and not to show off.
