Who hasn’t already experienced itchy skin? The infamous "…but it’s itchy!" is a well-known expression in every family. Learn more about itchy skin.
Itchy skin or “pruritus” is a common problem. Pruritus is clinically defined as a subjective and unpleasant sensation that provokes the desire to scratch. It is not a disease, but rather a symptom that is felt when the skin sends the nervous system a message, telling you that there is an underlying problem.
The itching sensation is in fact the result of substances released by the skin that activate specific receptors, and these messages send the information to the brain through the spinal cord. In very simple terms, the brain receives the following message, "The skin is itchy—there must be something wrong."
Itchy skin can result from a multitude of causes and triggers. Here are some examples.
Itching is often a sign of dry skin. In general, the drier the skin is, the more it tends to itch. Dry skin can occur at any time during the year, but most often in winter. You can prevent it by moisturizing your skin, which helps to keep it soft and healthy.

If your skin itches, it is normal to have the reflex to scratch. This certainly provides momentary relief, but it can also have unfortunate consequences such as irritating the skin, worsening pruritus, and increasing the risk of infection. Instead, gently massage the area of the skin that itches with the palm of your hand, while applying some pressure.
