Brett McKay here and welcome to another edition of the Art of Manliness Podcast.

You probably know your body follows a circadian rhythm and probably think of it as

primarily regulating your sleep wake cycle, which it certainly does. But your body's internal

clock also regulates many other physical, mental, and behavioral changes that occur every 24 hours.

And working with your circadian rhythm, rather than against it, can boost your health and happiness.

Here to unpack how to do so is Russell Foster, professor is Circadian

Neuroscience and the author of Lifetime, Your Body Clock and its essential roles in

good health and sleep. In the first part of our conversation, we discuss some science and background on

circadian rhythm and its connection to light exposure. We then turn into the

practical implications of having an internal clock, including whether you need to worry

about viewing blue light at night,

the significant mental and physical harms that can accrue from working the night shift

and what could be done to mitigate them, what influences your

chronotype and whether you're a morning lark or night owl,

whether you should be concerned if you're waking up in the

middle of the night, while you wake up to pee in the night, the best times a day to exercise,

and have the circadian rhythm can influence when you should take medication.

I. really.

So, you know,

All right, Russell Foster,

welcome to the show.
