Why Do Skin Rashes Appear?

Skin rashes are a common condition that can affect anyone at any age. They appear as changes in the skin’s color, texture, or appearance and can be accompanied by itching, redness, bumps, or blisters. While many rashes are harmless and temporary, some may indicate underlying health issues. Understanding why skin rashes appear can help in identifying the cause and finding the right treatment.

One of the most common causes of skin rashes is allergic reactions. These occur when the immune system reacts to substances such as certain foods, medications, or contact with plants like poison ivy. Allergic rashes are often itchy, red, and may appear suddenly after exposure to the allergen.

Infections can also cause rashes. Bacterial, viral, or fungal infections may produce distinct patterns on the skin. For example, chickenpox creates small, itchy blisters, while fungal infections like ringworm cause circular, scaly patches.
