Brain chemicals impact our emotions and behaviors from "summary" of Habits of a Happy Brain by Loretta Graziano Breuning
Our emotions and behaviors are influenced by brain chemicals that evolved to promote survival in mammals. These brain chemicals are designed to reward behaviors that promote survival, such as finding food, seeking shelter, and reproducing. When we engage in behaviors that trigger the release of these chemicals, we feel good, and our brains learn to repeat those behaviors. Dopamine is a brain chemical that motivates us to seek rewards. When we anticipate a reward, dopamine is released, making us feel good and motivating us to pursue the reward. This system is designed to encourage us to engage in behaviors that are beneficial for survival, such as eating or mating. However, in the modern world, this system can be hijacked by artificial rewards, such as drugs or junk food, leading to unhealthy behaviors. Endorphins are another brain chemical that promotes survival by reducing pain and promoting bonding. When we engage in activities that trigger the release of endorphins, such as exercise or socializing, we feel good and are more likely to repeat those activities. This system is designed to encourage behaviors that promote physical and social well-being. Oxytocin is a brain chemical that promotes bonding and social connections. When we engage in behaviors that trigger the release of oxytocin, such as hugging or bonding with loved ones, we feel good and strengthen our social connections. This system is designed to promote cooperation and social cohesion, which are important for survival in social species like humans. Serotonin is a brain chemical that regulates mood and social status. When we engage in behaviors that boost serotonin levels, such as achieving goals or asserting dominance, we feel good and increase our social status. This system is designed to promote behaviors that enhance our social standing and increase our chances of survival. Understanding how brain chemicals influence our emotions and behaviors can help us make healthier choices and cultivate habits that promote well-being. By being mindful of the ways in which our brains are wired to seek rewards and avoid pain, we can work towards creating a happier and more fulfilling life.
