ABOUT THIS EPISODE

You say you can’t sleep? Baby I don’t know. Is it that “me espresso?” Or is it something else? This week on Health Wanted, we’re talking about America’s favorite psychoactive substance: caffeine!

We also talk with UCSF cardiologist Dr. Greg Marcus about the potential cardiovascular benefits and drawbacks to drinking caffeinated coffee.

Plus: Are cold plunges worth the pain? Are there any benefits to “touching grass?” Debunking recent public health headlines. And some highs and lows for vaccine access.

For a full rundown on all the information shared in today's episode, take a look at the show notes.
