Mind Matters: Exploring Human Psychology

The Role of Hormones in Psychology – Chemical Influences
This episode explores how hormones act as powerful chemical messengers influencing human psychology. It explains how the endocrine system works alongside the nervous system, shaping emotions, decisions, and behavior. Key hormones are highlighted:
- Cortisol: the stress hormone, vital for short-term survival but harmful when chronically elevated.
- Adrenaline: fuels the fight-or-flight response, sharpening alertness but leading to restlessness when overstimulated.
- Oxytocin: promotes bonding, trust, and empathy in social relationships.
- Testosterone and Estrogen: influence competitiveness, mood, emotional sensitivity, and behavior in both men and women.
- Dopamine and Serotonin: function as both neurotransmitters and hormones, driving reward, motivation, and mood regulation.
The episode highlights how hormones impact stress, attraction, aggression, mood cycles, and decision-making. It emphasizes the delicate balance of the body’s chemical system, noting that lifestyle choices like sleep, diet, exercise, and mindfulness play critical roles in regulating hormones.
The central message: psychology isn’t only in the mind—it’s in the body too. Hormones shape who we are, guiding our emotions, relationships, and resilience in everyday life.
