Scientifically proven: scratch really itches and hurts more if her comb
Remember as a child my mother said do not comb the place mosquito bite, because it will be scratched even more? Mom was right: that there is scientific proof.
Heroic team of scientists from the University of Washington School of Medicine in St. Louis recently published study in the journal «Neuron», confirms the correctness of mothers all over the world. Biology phenomenon is quite simple, but amazing in its own way: in the case enters serotonin, the so-called "hormone of happiness».
Director of the School Center for the Study of itching Zhou Feng Chen describes it this way:
"At first you scratch, because you hurt. To control the pain, the body produces more serotonin, the hormone of happiness but only suppresses pain. Our new discovery shows that it also increases the itching by activating GRPR-neuron through receptors 5HT1A ».
blockquote> The meaning of abbreviations complex is reduced mainly to how nerves communicate with the entire body to the brain. Scientists have discovered the connection of neurons and receptors with itching after tests on two groups of mice. The first group of mice were completely normal and the second group of mice were unable to produce serotonin. When their skin irritated chemically so that the skin itching, the second group of mice scratched much less.
Well, useful information. So, to sum up: if you are bitten by a mosquito or burn the nettle, not scrub the affected area, and strike the best special ointment.
