Why do itching wounds?

We are talking about an experience that probably each of us has already done. Whether cycling, shaving or just doing housework - we hurt ourselves. At first we feel strong pain, then the wound seems numbed. When scabs form over the injury and the healing process begins, we often feel a strong itch. Why do healing wounds itch and what can be done about it?

Itching - a good sign

The itch of a wound is not something that should worry us. It is even a good sign and shows that the injury is in the healing process. Our body is like a coordinated organization in which each cell has its function and mission. In order to coordinate processes, the cells exchange messenger substances among themselves. These biochemical substances serve as a means of communication of the cells.

The messenger substances irritate the wound

In case of an injury, this organization gets temporarily out of balance. Suddenly numerous repair cells are activated, which have to restore different skin layers. The cells have to rearrange and initiate the fastest possible healing process. In order to avoid blood loss and an increased risk of infection, the cells must be strengthened and, above all, communicate quickly. Since the wound is very sensitive, it is irritated by the messenger substances of the cells. As a result, we feel the itching.

What to do when itching?

It is very tempting to give in to the itching and scratch the wound, but we should definitely avoid that. Bacteria could invade the untreated wound and cause inflammation. A much better remedy is to cool the wound. The nerve cells no longer transmit the itch to the brain, but the cold.
