there is evidence that estrogen levels are really a strong driver of circadian rhythms.

So the more estrogen you have in your body circulating,

it seems the stronger your rhythms.

And we know circadian disruption can drive metabolic disease.

It can be an underlying factor potentially for dementia

and all these consequences that come with aging.

Well that's Lynn Peoples.

She is an investigative science journalist who wants us to start listening to our body clocks for the sake of our health.

This is the Liz Earl Well-being show, the podcast helping us all have a better second half.

I'm Liz Earl and as you know I'm on a mission to find ways for all of us to thrive in our

later lives by investing in our health and our well-being today. Now do you listen to your internal body clock? Does it tell you when to eat and

when to sleep or have habits and just culture overridden the signals your body is trying to give you. So I had a genetic test not long ago which showed that I was genetically

predisposed to being a night owl and actually I am super happy to stay up late at night working not best perhaps for

longevity and circadian health and I am trying to educate my epigenetics, manipulate my status to be an early riser.

So I'm going to be very interested to chatting to Lynn to see just how possible that is.

Or indeed, is it a viable option?

Is it something that we should all be doing?

As an investigative journalist Lynn has spent her career reporting on science, health and the environment.

Now she's written a book called The Inner Clock in many ways exploring

the intersection of all those things. She's been investigating the fascinating science of

circadian rhythms and how our body clocks are being threatened by modern lifestyles.

How are clock scrambling streetlights, smartphone screens, arbitrary time zones, and constant snacking wreaking havoc on our health.
