Heat Rash vs. Allergic Reaction

Both the skin diseases are not easily diagnosed by the common people as in both the situations the affected area mostly gets red and a continuous itching takes place. Heat Rash mainly happens during hot, humid weather, when the sweat glands get blocked primarily due to tight clothing or extreme heat in the summer. The infants and obese people are mostly among those affected with heat rash.

Allergic Reaction is the hypersensitivity of the immune system to something in the environment that usually causes little or no problem in most people. The immune system gets triggered as the thing or substance affecting is perceived as a foreigner by the system.

What is Heat Rash?

Heat Rash is a skin condition when sweat ducts are obstructed mainly due to the warm weather. People are of the strong opinion that heat rash only takes place in extreme summer, though it can even affect the skin in winters if one wears a tight dress or goes on long journeys while sitting in congested condition. Heat Rash is also known as prickly heat and miliaria, the infants are mostly affected by this condition, while obese and elder people are the other two suffering from this skin condition.

This skin condition at the primary stage can easily be dealt with wearing loose clothing and applying heat rashes cream. The other precaution is to remain away from the hot and humid weather until the condition gets good.

What is Allergic Reaction?

Allergic Reaction is a skin condition which happens due to the hypersensitivity of the immune system to something in the environment that usually causes little or no problem in most people. The affected person is asked to stay away from the factor which he or she is allergic to. Steroids, antibiotics, and antihistamines are used for the short course by the affected to get back in healthy condition.

In Allergic reaction immune system gets collapsed somehow and certain factor recognized as ‘invader’ is not perceived well by the body. For Instance, eating peanuts causes no problem to most of the people through one suffering from this kind of allergy will have the reaction of it on skin.
