For Babies, Getting Care Relieves Pain in Medical Procedures
If medical procedures scare and hurt even adults, imagine what it can trigger in babies? An English study examined the effects of small strokes gently during a blood test. The researchers found that warmed infants felt less pain.

The discovery was made from an experiment that was monitoring the brains of 32 babies while they were drawing blood. Half of the group fondled during the procedure showed a 40% smaller pain-related cerebral activity.
"Touch seems to have a potential badgesic effect without the risk of side effects", explains Rebeccah Slater researcher. The explanation lies in the fact that care activates a clbad of sensory neurons in the skin that are already linked to a decrease in pain in the adult.
The study also suggested an ideal speed for small caresses: 3 centimeters per second. It's hard to calculate, but according to the researcher, parents are already doing it intuitively.
The research of Oxford University with the John Moores University of Liverpool was published in the journal Current Biology .
