Caffeine is in many things like coffee, tea, soda, and chocolate. A lot of people say they need it to start their day. But why does it make us feel better? Scientists did a study to find out. They gave volunteers caffeine tablets and watched their brains using a special scanner. The study showed that caffeine changes our brains by boosting a chemical called dopamine. This chemical makes us want things that make us happy. Unlike drugs like cocaine, caffeine increases the number of places where dopamine can attach in our brains, making us feel awake and alert.
