Why do wounds itch?

We are talking about an experience that probably each of us has already had. Whether it’s riding a bike,  shaving ,  or just doing housework, we injure ourselves. First we feel severe pain, then the wound seems numb. When a scab forms over the injury and the healing process begins, we often experience intense  itching . Why do healing wounds itch and what to do about it?

Itching – a good sign

The itching of a wound is nothing to worry us about. In fact, it is a good sign and shows that the injury is healing. Our body resembles a coordinated organization in which each cell has its function and task. In order to coordinate processes, the cells exchange messenger substances with each other. These biochemical substances serve, so to speak, as a means of communication between the cells.

The messenger substances irritate the wound

In the event of an injury, this organization is temporarily thrown off balance. Numerous repair cells are suddenly activated, which have to restore different layers of the skin. The cells have to rearrange themselves and initiate the fastest possible healing process. In order to avoid blood loss and an increased risk of infection, the cells must communicate with each other more intensively and, above all, quickly. Since the wound is very sensitive, it is irritated by the messenger substances in the cells. This makes us feel the itch.

What to do when itching?

While it’s very tempting to give in to the itch and scratch the wound, it’s something we should avoid at all costs. Bacteria could enter the unhealed wound and cause  inflammation  . A much better tool is to cool the wound. The nerve cells no longer transmit the itch to the brain, but the cold.
