If you look at when they inject, not so much injure you

What you see may affect the amount of pain that feels, reveals a survey.

They are generally told the children to look on the other hand when they click.

Unlike many people stress to be considered in the other meaning of a painful event as an injection, scientists have discovered that observe can be used as an analgesic.

The team also showed that enlarge the size of the area of the body suffering, to reveal more wholesale, smaller pain.

The study, published in psychological Science highlights how the brain processes pain.

Researchers that only a better understanding of this mechanism may lead to new treatments for chronic diseases.

18 Volunteers participated in search of the University of London (UL) and University of Milan-Bicocca, funded by the biotechnology and biological sciences (BBSRC), Council of research.

My advice would be looking at the arm, but try not to see the needle if possible

Patrick Haggard, University of London.

Scientists applied tube of heat in the hand of each participant, gradually increasing temperature. As soon as it starts to feel pain, the probe has been withdrawn and measured temperature.

Patrick Haggard, Professor of cognitive neuroscience of UL, explains: "this we provides a measure of the pain threshold and is a safe and reliable way of measuring brain pathways that reveal the pain when it is activated.

Scientists used a set of mirrors to manipulate that given volunteers.

The team saw that volunteers can tolerate an average 3 ° C more heat when they saw his hand in the mirror, compared to when his hand was masked by a wooden block.

Haggard, explains: "they always advise children not to watch when they are in an injection or a sample of blood taken, but we discovered this look on the body is an analgesic: just watch it reduces the levels of pain."

"So my advice would be looking at the arm, but try not to see the needle if possible.

In another experiment, the researchers used convex mirrors to enhance the appearance of the hands of the participant. They saw for doing so, volunteers could tolerate higher temperatures.

Conversely, when the lorsque l' équipe team has done in the hands of volunteers more small, their pain threshold has decreased.

The study to understand how the brain processes pain.

Point researchers on the fact that pain levels are directly proportional to the size which is seen body helps understanding the neurological foundations of pain.

Haggard explains: "we learned a lot about pathways leading body pain to the brain signals, but we know much less how the brain processes signals once they arrive."

"Our interest focuses on the relationship between the experience of pain and representation brain makes your own body."

And we found that there is an interesting interaction between Visual brain connections and pain in the brain.

Researchers hope that a better understanding about the science behind pain can help find new treatments for chronic diseases.

Dr. Flavia Mancini, principal author of the article said: "psychological treatments for pain generally focus on the origin of the pain, for example, changing expectations or care."

"However, think beyond the painful stimulus in our own bodies can lead to new clinical treatments."

And doctors say that it is vital.

Dr. Paul Nandi, consultant in medicine for the pain of the Centre of London University Hospital pain management explains: "pain is a huge problem in national service health and society in General."

"We have no precise figures, but it affects millions of people in the United Kingdom and has a major impact on the quality of life."

"Also produces a huge economic burden - looking only chronic back pain it is estimated that costs 16 billion pounds ($ 25,000 million) per year."

"But it is still very little appreciated, and he has not received much attention and resources to other areas that are perceived as"exciting"in the medical profession."
