In this episode, Greg Dickens and I discuss recent news on how hanging and swinging from the arms affects the length and strength of our upper body muscles. We discuss how SSRI antidepressants alter gut function, and how new drug targets may better help new mothers. We then talk about the links between sugar and metabolic syndrome, and how the scientific understanding is evolving.
We then discuss children’s independent mobility and exploration - what it is, why it’s important, and why it’s hard to provide in our culture. We then talk about how we navigate this, and how we reassure other adults in our community.
Finally, we talk about what movements are important for setting up abdominal muscles that are the right length and strength.

My veterinary degree taught me about mammalian body systems.
My career in health research taught me about Western health and Western bodies.
Spending 18 months living with my three children in remote African and South American communities taught me about human health and human bodies in other cultural environments.
I share what I’ve learned about child physical health and development in weekly articles and podcast episodes.

“This theoretical paper proposes that brachiation-based movements—particularly unilateral hanging with oscillatory perturbation—may offer a biomechanically optimal approach for addressing Upper Crossed Syndrome and related postural dysfunctions by restoring muscle activation patterns consistent with our evolutionary heritage.” https://www.sciencedirect.com/science/article/abs/pii/S1360859226000148
