Emotions are an integral part of human life. They not only influence our behavior, but also shape the way we make decisions, communicate, and even our physical and mental health. But have you ever wondered what exactly emotions are and how they form in our bodies and minds?

What are feelings?

In general, emotions are complex reactions that arise from the interaction between our brain, body and external environment. Each emotion consists of three main parts:

• Subjective experience: What we feel inside, such as happiness, sadness, or anger.
• Physiological reaction: Physical changes such as increased heart rate or hormone secretion.
• Behavior or expression: a reaction we express outwardly, such as smiling, crying or silence.

The American Psychological Association (APA) defines emotion as "a combination of mental, behavioral, and physiological responses to events." In other words, emotions are a reflection of our inner understanding of the outside world.
