The urge to scratch itching may have evolved because of the reason, but we struggled to grasp the reason.

Forget what your parents said. Scratching itching is a good idea to increase your body’s defense of bacteria.
Scratches are paradoxical phenomena. It may be better to run your nails over itchy skin. This suggests that there is an evolutionary reason that we do through what we do, but it can worsen eczema and rash or resume wounds.
To dig this dichotomy Dan Kaplan Pennsylvania Pittsburgh, Pennsylvania and his colleagues, used an allergens called Haptens to cause eczema in the ear of mice.
The ears of the scratched mouse have more inflammatory cells, called more swelling and called neutrophils.
To see how this scratch affects the skin, researchers have investigated what’s happening inside the cell. They have found that scratches release chemicals known as a pain detection neuron, and then activate white blood cells called mast cells to encourage the body to produce more neutral venues.
“Scratching shows that it is really important for boosting obesity. Holly Wilkinson At Hull University in England.
The team also reduced the amount of scratching force. Staphylococcus Au LesusBacteria are generally involved in skin infections in the skin of mice. This microorganism can cause many skin inflammation that appears as dermatitis, Kaplan says. “About 24 hours of scratches are enough to change the microbial cluster in a measurable way,” he says.
However, by activating obesity cells, allergens also induce a path that causes inflammation, and shows that the body effectively obtains the dual dose of skin inflammation in the type of dermatitis in the same state as eczema. Increased damage.
Wilkinson said, “Basically, if you have healthy and scratches, it’s a good thing. “But that’s the tip point and too much scratching can be a negative thing.”
Kaplan said his team had a preliminary work that showed similar benefits from people’s scratches.
