Abstract This project’s goal is to examine the neurochemical effects of Screen Time and Green Time on adolescents. Screen use triggers dopamine, cortisol, and adrenaline, resulting in an increase of stress, anxiety, and cognitive fatigue. Conversely, Green Time releases serotonin, BDNF, endorphins and oxytocin, promoting restoration and well-being. Using 3D modeling I explored how Green Time can counteract screen-induced chemical effects supporting healthier brain and body development.
