You may have noticed that a wound during the healing stage itches a lot, sometimes causing unbearable itching.
It turns out that there are several reasons for this phenomenon.
First of all, the hormone histamine is to blame – it is released when the body senses the danger of invasion by allergens, toxins and other, so to speak, “troubles”.
Histamine, in turn, makes the cells of the immune system work, providing optimal conditions for their functioning and preventing the spread of infection in the body.
The listed processes are accompanied by the appearance of edema and slowing of blood flow.
What's funny is that histamine itself is an allergen.
It can trigger asthma (swelling of the airways).
But let's not dwell too much on histamine - the second cause of itching can be an allergic reaction.
Finally, as a final factor that causes itching in a healing wound, we will name the process of regeneration of damaged nerves.
As tissue grows to replace the lost tissue, the new nerves are constantly irritated, which the brain perceives as an itch.
Earlier we talked about how to learn to wake up feeling rested.
