Why does coffee sometimes make me sleepy?

Why Does Coffee Sometimes Make Me Sleepy? You drink a coffee expecting a boost of energy… …and somehow, you end up feeling more tired than before. But why? How can something we drink to wake ourselves up sometimes make us want to curl up on the couch instead? Is coffee actually making us tired — or is something else going on beneath the surface? In Episode 11 of One Rabbit Hole, we dive into the surprisingly strange science behind one of the world’s most popular drinks — and why that much-needed caffeine hit doesn’t always have the effect we expect. What does caffeine actually do to your brain? Why does it block the chemical that makes you feel tired? Why can some people drink coffee at night and sleep perfectly, while others are wide awake for hours? And could your morning coffee actually be contributing to that afternoon slump? Join us as we follow coffee down the rabbit hole — exploring caffeine, sleep pressure, tolerance, brain chemistry, genetics, and the strange ways our bodies can react to the world’s favourite pick-me-up. Because sometimes the thing you’re drinking to wake yourself up… might not be doing quite what you think. One Rabbit Hole is the podcast where no question is too weird. Off Script. Off Limits.
