Summary

Elise Facer-Childs is currently a Doctoral Researcher working at the University of Birmingham on sleep, circadian rhythms and neuroimaging. She works with human participants to uncover the impact that our body clocks can have on brain structure and function, genetics, physiology and performance.

Elise has presented her research at an International Conference for the European Biological Rhythms Society (EBRS)/World Chronobiology Congress (WCC) and has given presentations at the UK’s largest circadian conferences (UK Clock Club).

In This Episode We Discuss
Understanding circadian phenotypes
Neuroimaging (fMRI) to understand how the brain is affected by time of day
Time of day vs. time relative to internal circadian clock
Practical implications for “night owls” and “morning larks”
Personal best performance times differ significantly between circadian phenotypes
Circadian phase shifting

0:00.0	And there have been a handful of studies that have looked at functional MRI depending on time of day.
0:20.0	And a couple of studies have shown that there is actually a rhythm to our brain activity over the course of the day,
0:29.6	which you might you could expect if you think everything else shows a rhythm and there's a time of day where we feel sleepy and a time of day
0:39.8	when we're looking more alert. But the fact that we're showing this in certain areas
0:44.5	of the brain now is really fascinating. Hello and welcome to Sigma Nutrition Radio.
1:04.4	As ever, I am your host, Danny Lennon.
1:06.7	We are at episode 241 of the podcast today, and we've got an absolute cracker lined up on today's show.
1:15.2	But before I get into that, a very, very special announcement, one that I have been sitting on for quite a while that I'm extremely excited about.
1:24.3	And that is that this November is going to be the very first ever Sigma Nutrition
1:30.3	Radio Live. It's going to be a live recording of the podcast in front of an audience where you can
1:36.1	get tickets with a number of very, very special guests. The first of these events is going to be
1:43.0	happening in Dublin, Ireland,
1:45.0	on November 24th. And over the next couple of days on my Instagram and Facebook, as well as
1:51.8	to the email list, I'm going to be announcing the names of these very special guests. And essentially,
1:57.2	the event that's lined up is something that's taken a lot of planning, but I think
2:00.9	is going to be incredibly, incredibly cool.
2:03.3	We've got a fantastic venue that I'm going to be announcing over the coming days in the
2:08.8	centre of Dublin that is going to be set up with stage.
2:12.3	We're going to have tables for you guys to sit, get to know each other.
2:15.5	There's going to be lots of cool, like-minded people going to be there. And like I said, throughout the day, we're going to have these
2:21.3	conversations with some of the best world experts in the terms of evidence-based nutrition
2:27.2	and nutritional science research. So that is the setup for the day. Throughout the day,
