When an irritating substance breaks through the surface of the skin, your skin lets you know something is wrong. Unfortunately for those who have sensitive or dry skin, the layer of skin is usually thinner than usual.
This means the nerve endings under the surface of dry or sensitive skin detect everything much more quickly. The result is skin rashes from the temperature, clothes, other people and substances.
Some of the most common causes of itchy skin and rashes include:
- Allergic reaction: When an allergic rash breaks out on your skin it is your skin letting you know that the chemicals it has contacted are too harsh.
- Heat: Heat rashes are very common, especially in summer, and are mostly harmless. They flare up when your pores are blocked and can’t secrete sweat properly, usually caused by wearing excessively tight clothing on a hot day.
- Eczema or psoriasis: Eczema and psoriasis are two more serious skin conditions that cause you to break out in a rash that reoccurs. The dry, patchy rashes can break out anywhere but most commonly around the hands, elbows, back of the knee, face and ankles. Visiting a doctor to understand what causes the flare ups is the first step to understanding the condition.
- Bacterial or viral diseases: A skin rash may also be a sign of an underlying bacterial or viral disease or infection in your body. Diseases or infections like scarlet fever, impetigo, shingles, chicken pox and measles can cause mild to severe rashes on your skin. The doctor is the best person to get advice from in this case.
