Do you know what happens in your body when you ingest coffee?
In the first ten minutes caffeine iz coffee enters the bloodstream and spreads throughout the body, causing increase in blood pressure and heart rate. At the same time, it prevents dopamine from being reabsorbed into the bloodstream, which allows it to remain in the brain for a longer time, which makes us feel positive and happier for longer. Exactly this retention of dopamine is what often triggers the brain to crave more caffeine.
