To look at the needle in an injection, pain is decreased

February 10, 2011

According to a research published in Britain, “People that fear injections may feel less pain if they look when the needle enters their skin, rather than looking to other way”.

Specialists from University College in London established the relationship between pain and sight. The scientists applied heat to the hands of volunteers and they stopped when it became a painful experience for them and the conclusion was published in the journal Psychological Science, which states “The volunteers were able to tolerate more pain when they could see what was happening”.

According to scientists, the research helps to understand how the brain processes pain, which may help to develop treatments”.
