[00:00:00]Is it true that a smell can help you remember what you studied?

[00:00:03]Surprisingly, yes. Scientists call this the encoding specificity principle. Your brain remembers information better when the context during learning and recall is similar. Smell is especially powerful because it's directly connected to the limbic system, the part of the brain that controls emotions and memory. So, if you study while smelling mint and smell the same scent during a test, it can help trigger the memory. It's not magic, but your brain loves familiar clues.
