Studies conducted in the United States show that when parents kiss their children's wounds or aching places, physical pain is reduced.
"Let me kiss"
It seems that the mothers and fathers saying "let me kiss and pass" relieves the pain physically. When they fall, the elders, including parents and siblings, approach the children with love and say, "Let me kiss them." They want to relieve pain with their love.
A University of Pittsburgh study found that parental touch reduces pain in infants from different diseases.
Parents kissing the child's aching place contains an important message for the child.
Researchers state that the child whose wound is kissed by his mother or father heals more quickly than the one who is not kissed.
