This is a review of literature regarding the biochemicals of happiness and various human behaviors that can decrease or increase happiness. Happiness is a raw emotion experienced by individuals as they are in a state of contentment and positive well-being. “Pura Vida,” a Costa Rican philosophy meaning “pure life,” emphasizes simplicity, gratitude, and a connection to nature. This lifestyle approach is linked to higher life satisfaction and lower stress levels, contributing to Costa Rica’s being perceived as one of the happiest countries. However, mental health care in Costa Rica faces multiple disparities, resulting in decreased access and an increasing numbers of patients with untreated mental health conditions. Meanwhile, harmony in workplaces fosters an environment that positively influences both mental well-being and physiological responses. Research indicates that reduced stress and increased collaboration enhance hormonal balance, particularly lowering cortisol levels and boosting oxytocin. Such changes improve teamwork, productivity, and overall job satisfaction. This topic explores the interplay between workplace dynamics and hormonal health, offering insights into creating a balanced and thriving professional environment. Additionally, exercising and listening to music are two behaviors humans can directly partake in which influences their level of happiness. Exercise profoundly impacts hormone regulation, promoting physical and mental health. Aerobic and strength training activities stimulate the release of endorphins, serotonin, and dopamine, improving mood and reducing anxiety. One study delves into the mechanisms by which various forms of exercise influence hormonal pathways and long-term wellness. Lastly, another study explored how music profoundly affects the brain and body, influencing emotions, cognition, and physical health. Prior studies showed that listening to music can reduce cortisol levels, enhance dopamine release, and improve mood. This topic examines the neurological and psychological mechanisms of music’s impact, highlighting its therapeutic and transformative potential.
