Skin rashes are a common condition that can affect people of all ages. They appear as changes in skin color, texture, or appearance and may be accompanied by itching, redness, swelling, or pain. Understanding what causes skin rashes is the first step toward effective treatment.
One of the most common causes of skin rashes is allergic reactions. These can occur after contact with certain foods, medications, cosmetics, detergents, or plants such as poison ivy. The immune system reacts to a substance it considers harmful, leading to inflammation of the skin. Another frequent cause is skin infections, including bacterial, viral, or fungal infections. Conditions such as chickenpox, ringworm, or impetigo often present with visible rashes.
Skin rashes can also be triggered by chronic skin conditions like eczema, psoriasis, or rosacea. These conditions are often linked to genetics, immune system dysfunction, or environmental factors. In addition, stress, heat, excessive sweating, and poor hygiene can irritate the skin and lead to rashes, especially in sensitive individuals.
