Scratching is Addictive

Hey English Tutorial Group 21, I want to share about a recent article I read from the internet. It is about how scratching is very addictive. Scratching can be addictive just by watching someone else who is scratching. It is called 'transmission scratching', and can cause a room full of people to start to scratch. This is the same as watching people yawn. We tends to follow the person action without our own aware. A dermatologists at the University of North Carolina said that scratching can become addictive because our brain become extra sensitive when we see someone else scratching. Therefore, our brain detect any change in the skin connect to scratching. An experiment has been done to help people who suffer from chronic scratching and other skin diseases.
