Age Better with Liz Earle · Why sunlight is key to a longer, healthier life – with Rowan Jacobsen · 26 Jun 2026 podcast

Like, I don't mind the cold as long as, you know, I get out and exercise in it.

But and everyone up here says the same thing.

It's the dark that gets us.

And part of my interest came because I started seeing a great deal of research that, you know, you're familiar with as well, showing us that that dark really does have a huge impact on our physiology.

Yeah, my beliefs have transformed as I've dived into into the science.

And, you know, I think back in the day, I pretty much had inherited the conventional wisdom on on these topics.

So I knew that the sun could raise your risk of skin cancer.

So you should avoid too much exposure to it.

You know, I sort of dutifully did that.

I tried not to get any extra sun exposure.

Never felt great.

I was resisting my natural instinct, I think, to get in the sun because you do get a hit of endorphins when you're in the sun.

And I knew that vitamin D was produced when sunlight hits skin and that you need vitamin D. But the public messaging is always to avoid the sun.

And in terms of vitamin D deficiency, you can take a pill if you need to.

So that was kind of where I started from.

But then as I dived into the research, I learned that vitamin D pills don't seem to be an effective replacement for the things you're not getting when you're outside of the sun.

And as you referred to in your introduction, there's been some very significant studies that have come out showing that

People who basically have a deficiency of sunlight in their daily lives tend to have higher rates of all the chronic diseases, all of which, of course, rise as you hit middle age and older age.

So there does seem to be a connection there.

You know, that is the exact question that I asked myself when I was starting to work on my book.
