Research by Barbara Fredrickson discovered that insincere “social” smiles have a negative impact on our bodies. The test group was hooked up to sensitive monitoring equipment. They were then placed in casual social circumstances with strangers. When an insincere social smile was received, the monitoring equipment detected a microscopic collapse in the heart lining. The conclusion was that insincerity and phoniness could contribute to long-term heart health problems.
Conversely, when someone smiled at the test group with sincerity (when the muscles around the eyes and face contracted) the monitoring equipment showed benefits to the heart.
Smile at folks today with attention and genuine interest.Your smile could contribute to the health and well-being of those you meet today.
