Why does heat rash occur?

Heat rash is about skin lesions that appear due to the obstruction of the sweat ducts; this obstruction does not allow the exit of sweat from the skin, which is trapped under it.

The appearance of these lesions is due to different factors that produce the obstruction of the sweat ducts, among which we can mention:

  • Immaturity of the sweat ducts: this can be seen in babies due to the lack of development of these ducts; in many cases, they break, thus leaving sweat trapped under the skin. It can be seen in children who remain in an incubator to keep warm due to excess clothing or in cases where they have a fever.
  • Physical activity: the practice of an intense exercise or a job that requires a more significant effort that generates increased sweating can give rise to these skin lesions.
  • Excess heat: when the body is subjected to excessive heat or overdressing, the risk of suffering from this alteration.
  • Exposure to tropical climates: being under the influence of hot and humid climates is a trigger for the appearance of these skin lesions.
