053: Circadian Rhythms, Chronobiology, and Interoception with Azure Grant, PhD


Today, we are joined by well-versed physiologist, Azure Grant, Ph.D. to talk about all things circadian and ultradian rhythms, melatonin, sleep optimization, hormones, and more! Azure has a specialization in chronobiology and studies the connections between metabolism, reproduction, and the autonomic nervous system (ANS). In this episode, we touch on everything from the science behind the siesta ‘slump’ and the effect of caffeine on our sleep cycles, to the importance of reducing the causes of fatigue, not just the sensation of fatigue. Azure explains circadian and ultradian rhythms and fills us in on the health benefits of optimizing our natural oscillations. We discover what it might feel like to live according to our chronotype, and how biometrics play a role in interoception awareness. We also find out the long-term effects of melatonin supplements, how best to naturally optimize sleep, how women’s hormonal changes affect thermoregulation, and so much more! Tune in to find out more about how our biological rhythms work, and about the natural ebbs and flows that are essential to optimal health!
