There are a lot of causes for the rash after shower. The most common cause may be because of an allergic reaction to the chemicals that are present in water.

Causes of Rash After Shower

Causes of Rash After Shower

Water Urticaria or Aquagenic Urticaria

One of the causes of rash after shower could be Water urticaria or Aquagenic urticaria. This is a rare condition where hives develop within 1 minute to 15 minutes after being in contact with water. These hives generally last for 10 minutes to 120 minutes. Most researchers believe that such a condition is actually exquisite skin sensitivity to additives found in water, such as chlorine. Water urticaria is sometimes described as a “water allergy” which however, may not be accurate.

In case you do not have water urticaria and still noticing rashes on your skin after shower, then it may be caused from the chlorine present in your water. Tap water usually contains more chlorine than the amount recommended for use in swimming pools. In such case, while showering more chlorine enters the human body through inhalation than through drinking tap water.
