According to speech therapists Mirtha Manno and Rubén Delauro, who manage a self - help clinic called Smiling and Health, the mere gesture of smiling produces an electrical stimulus that affects the pituitary gland.
Kõneterapeudid Mirtha Manno ja Rubén Delauro, kes juhivad eneseabikliinikut Naeratus ja Tervis, ütlevad, et pelk naeratus tekitab elektrilise ärrituse, mis mõjutab ajuripatsit.
