Are you interested in genetics and epigenetics? Are you interested in living a healthy and natural lifestyle? Circadian genes turn on and off on a daily basis. My newsletter is about the things we experience (and do) that influence these circadian rhythms.

In other words, it’s about the science of living in time with nature’s rhythms.

What are readers saying?

Here are some of the nice things people have said about my publication:

  • I'm really loving this newsletter💕

  • Excited to be signed up! Your content is awesome, my friend!

  • Interesting write ups you're doing on circadian rhythms and the effect of sunlight on our overall wellbeing. Your last post especially on sunbathing is quite a read.

  • You have a wonderful ability to take the stilted jargon ridden science papers and make the topics friendly to digest. It’s just a real pleasure to get those emails.

But circadian health turns out to be a much bigger story than my own little woes…

Skin protects itself.
Sunscreen blocks most Vitamin D production. Therefore, sunscreen isn’t compatible with a sunbathing-rich circadian lifestyle. But how can we make sure not to get sunburned? I've had a lot of positive feedback from my post about the app Dminder, and thought I would follow up with even more of the research about how the skin adapts to solar exposure. I’d love to hear what you think! Feel free to login and start the discussion…
