Sweat Rash (Miliaria) : Causes, Symptoms, Risk Factors and Treatment

What is Sweat Rash?

The prime role of your skin is to offer protection to the internal part of the body from the external world. Acting as a barrier against invader causing chemicals, ultraviolet ray, infection or any other intruder which is potential to harm the body, the preventive nature of the skin is significant. Moreover, the skin has a role to manage body temperature and for this very reason, the body starts to sweat for cooling itself.

Perspiration or sweat is produced by the sweat glands that are spread across the body only except for the few parts like toenails, ear canal and fingernails. These glands are rooted in a deep layer of skin or dermis and essentially controlled by the temperature. In addition to the context, sweat manufactured from the gland reaches to the skin surface by the duct.

However, the development of miliaria as follows,

  • Sweat rash develops when this duct becomes clogged and sweat is unable to reach the skin surface
  • Gradually, sweat is trapped under the surface of the skin that causes a rash or mild inflammation

Adults are seen to develop the skin condition on different parts of the body that compel them to rub together in specific areas like underarms and inner thighs.
