The act of watching an injection actually makes it more painful according to a study. A team of researchers from St Hedwig Hospital in Berlin investigated how we react to the pain of shots based on what we're looking. And guess what they found?
In the experiments they conducted, researchers simulated needle pricks by giving participants a small electric shock on their hand. They were also shown videos of a needle pricking a hand, a Q tip touching a hand or nothing happening to the hand at all.
People who were watching a hand being pricked by a needle found the pain of the shock far more intense. In other experiments, participants were told that the Q tip would cause more pain than the hypodermic resulting in the Q tip video being associated with higher levels of "pain".
So one good way to withstand the pain? Don't look. Close your eyes. Take a deep breath. Look away if you must. But don't look at the needle. Its not all that bad. [Pain via Scientific American]
