and Health

Microexpressions, those fleeting subconscious facial expressions, have many applications in both the worlds of science and health. Understanding the science behind them can offer valuable insights into human interaction, stress levels, and overall health.

What are Microexpressions?

Microexpressions are brief, involuntary facial expressions that reveal a person’s true emotions. Although we may conceal our feelings, microexpressions give away the truth. From facial expressions, we can tell if a person is feeling happy, sad, angry, surprised, scared, and more.

The Science Behind Microexpressions

Facial expressions, which are associated with microexpressions, are portrayed because of certain muscles in the face. These muscles are activated when a person expresses an emotion. An example would be the zygomatic major, which is a muscle in the cheek that works to raise the corners of the mouth, giving away a genuine smile.

Microexpressions and Health

Microexpressions have become beneficial in both the medical field and psychology. By observations of microexpressions and facial expressions, people can detect whether a person is feeling any psychological distress and if so, what type of distress. This can help medical professionals diagnose people with mental health issues and provide a course of treatment.
