Is Caffeine Helping or Hurting You? with Stephen Cherniske

IN THIS EPISODE

Is your morning coffee helping or hurting your health?

The answer may depend on much more than how many cups you drink.

In this episode of the ReThink Health Podcast, I sit down with nutritional biochemist Stephen Cherniske, author of Caffeine Blues, for a nuanced look at one of the most widely consumed compounds in the world: caffeine.

Rather than labeling caffeine "good" or "bad," Stephen explains why your dose, timing, genetics, and individual response can completely change how caffeine affects you.

Stephen (who still drinks coffee himself) encourages understanding your own physiology and using caffeine strategically rather than mindlessly; a distinction that becomes especially important since people can metabolize and respond to caffeine very differently.

You'll learn:

Why caffeine doesn't actually give your body energy (and what it does instead)

The research-backed benefits of caffeine for cognition, memory, athletic performance, and metabolic health

Why the same amount of caffeine may make one person feel great and another anxious, jittery, or unable to sleep

How caffeine can interfere with deep, restorative sleep even when you think you're sleeping just fine

How your heart rate and sleep quality may provide clues about your personal caffeine tolerance
