Caffeine — it’s the world’s favorite stimulant and a daily ritual for millions. But what does it really do to your brain? In this episode of The Nourished Brain Podcast, we unpack the science behind caffeine’s short- and long-term effects on focus, mood, sleep, and brain health.

Learn how caffeine interacts with adenosine, the molecule that builds sleep pressure, and why older adults metabolize caffeine more slowly, leading to longer-lasting effects. We’ll also explore the latest research showing that moderate coffee and tea intake may lower the risk of Alzheimer’s and depression — but that too much can backfire on mood and sleep.

🔍 You’ll discover:

How caffeine really boosts alertness — and why that 3pm cup might keep you up at night
The role of genetics, age, and kidney function in how your body clears caffeine
What large meta-analyses reveal about coffee and tea’s protective effects on cognitive decline
Why caffeine’s effect on mood is bidirectional — and how to find your personal sweet spot

Whether you’re a latte lover or trying to cut back, this episode helps you understand how caffeine impacts your brain — for better and for worse.
