Smiling stimulates the amygdala
Scientists at the University of South Australia have conducted a groundbreaking study that has shown that smiling can make a person’s mind be more positive.
“In our research, we found that when you forcefully practice smiling, it stimulates the amygdala — the emotional center of the brain — which releases neurotransmitters to maintain an emotionally positive state. This has interesting implications for mental health, ” said Dr. Marmolejo-Ramos. According to the expert, if your muscles express happiness, you are more likely to perceive the world in a positive way.
He also noted that if people are capable of tricking the brain into perceiving certain stimuli as positive, then people, in theory, have ways to exploit this to improve mental health as well.
