Dr. Rangan Chatterjee

Hope you're having a good week so far.

My name is Dr. Rangan Chatterjee, and this is my podcast, Feel Better, Live More.

I believe that today's conversation will transform the way you think about your immune system, what it really does, why it matters, and what we could all be doing to support it.

My guest is Dr. Jenna Machoke, one of the UK's leading immunologists and someone whose work I've admired for years.

Since Jenna was last on my show back in 2020, she's been through some significant life changes, and that depth of experience is woven beautifully into her latest book, Immune to Age.

Now, you might think it's strange to focus on the immune system just as we're coming out of cold and flu season.

But that's the thing that most of us get wrong.

We think immunity is just about fighting infections.

In fact, as Jenna reveals, the immune system is a key player

in how we age, how much energy we have, and whether we develop chronic disease.

Jenna calls it our wellness system, and once you hear why, you won't think about your longevity in quite the same way.

Jenna gives one of the clearest breakdowns I've heard of how stress works in the body.

She explains the close links between chronic stress, immunity, and inflammation.

We talk about why midlife is such a critical turning point for your biology.

And we discuss what self-compassion, good oral hygiene, and even martial arts can do for our immune health.

What I love most about this conversation, though, is where else it takes us.

Jenna and I go way beyond the basics, talking about identity, alignment, and even pondering the meaning of life.

It's both practical and philosophical, scientific and surprising.

And I think you're going to find it incredibly powerful.

So settle in and let's get to know our body's all important wellness system a little better.
