Hormones and behavior

Hormones are chemical messengers produced by glands that travel through the bloodstream to influence various parts of the body, including the brain. They play a key role in regulating behaviors such as mood, aggression, stress response, and reproductive actions. For example, hormones like adrenaline prepare the body for fight-or-flight, while oxytocin promotes bonding and trust. The interaction between hormones and brain activity helps explain how biological factors can impact behavior, mood, and social interactions. Understanding this relationship highlights the complex links between our physiology and our actions.
