Episode 39: Cold Comfort - What Winter Rituals Got Right About Microbes

There’s more to your favorite winter rituals than nostalgia.

In this episode, we dive into how centuries of winter traditions—across Europe, Asia, Africa, and the Americas—offered accidental protection against infectious diseases. From citrus in stockings to cloves in mulled wine, from kimchi to candlelight, we trace how ancient practices around food, air, warmth, and cleaning helped communities stay healthier in the harshest season.

Learn how:

• Spices like cinnamon, ginger, and clove helped preserve food and reduce pathogens

• Fires, feasts, and fermentation doubled as primitive infection control

• Cleaning rituals and seasonal isolation slowed the spread of disease

• Modern public health can still draw lessons from these old traditions

We also address how today’s world—sealed homes, global travel, and misinformation—has changed the game, and why clear science is more important than ever.

🎙️ Plus: a discussion of the recent HHS decision under Robert F. Kennedy Jr. to remove the statement “vaccines do not cause autism” from federal pages—and why this political move contradicts decades of scientific evidence.
