Your circadian rhythm is ready to sleep, but your drive is down, because you got rid of some of that adenosine during your nap.

That circadian rhythm was just off.

There's also a circadian rhythm.

So the circadian rhythm is a lot-- it's really your biological clock.

So what is circadian?

We have these circadian clocks throughout our bodies, and they quite firmly run our physiology over a pretty strict 24-hour cycle.

And then circadian rhythms.

So based on Circadian rhythms during the day serotonin makes you feel alert, awake, you're calm but sort of alive and ready to go and keeps your mood elevated.

Russell Foster is a professor of circadian neuroscience.

His research dives into how circadian rhythms and sleep are generated and regulated and how modern life is

And then think about how Sleep and Circadian Rhythm Disruption, or SCRD, can impact upon our health and well-being,

between mental illness and sleep and circadian rhythm disruption.

Another really important area is Sleep and Circadian Rhythm Disruption on emotional processing.

I did my PhD in sleep and circadian genetics at Northwestern, and Meir literally wrote the book that anyone would start out with.

This is a function of your circadian clock.

that function it controls the Circadian rhythm you see circadian rhythm is the

fringe cases is when we actually legitimately need to reset circadian rhythm, travel, jet lag,

And he's the founder and director of the Sleep and Circadian Research Institute.

But that definitely sprung from being more in tune with the circadian rhythm, and looking at light and dark.

And he was able to show that his circadian rhythm persisted even in the absence of light.

Now, the fact is circadian rhythm ended up being about 24 and 1/2 hours.

This is a rodent that has a mutant circadian clock.

I'm going to talk to you about something called circadian rhythms, and what do they mean-- Joe's favorite word, circadian-- and what can we learn from them

I was interested to hear you talking about the circadian rhythm stuff on the submarines, especially because since I read--

temperature changes, circadian rhythms, sleep patterns, all of this.

So let's look a little bit at the generation of our circadian rhythms.

So this is a really important part of our circadian organization, the capacity

So that's the importance of circadian timing.

What I'd like to finish with is essentially working against our circadian rhythms and sleep and consider this Sleep and Circadian Rhythm

It's also worth bearing in mind that stress as a result of Sleep and Circadian Rhythm Disruption affects the immune response.

To conclude, by understanding our circadian rhythms and sleep and working with this deep biology, we can enhance every aspect of our lives,

and so we'll never have any Southern California sunlight disrupting our circadian rhythms.

After lunch, we have this circadian low, sometime between about 1:00 PM and 3:00 PM where our energy levels dip.

So the other thing that controls the timing of sleep is a circadian biological clock.

No, because the thing that melatonin is supposed to do is realign circadian rhythm.

it actually creates a pattern of neural inflammation in our brain in a place called the hypothalamus and disrupts our circadian rhythm,

So I'll give a sort of a general background on the regulation and generation of circadian rhythms.

And what's extraordinary about each of these cells is that they have the capacity to generate a 24-hour circadian

And finally, I want to talk about Sleep and Circadian Rhythm Disruption and its links with mental illness.

Otherwise, you can get really a whole massive of circadian rhythm disruption, bad for health and all the rest of it.

And we know that there's a-- we know that the world is based on-- every cell in our body has a circadian rhythm,
