In this Huberman Lab Essentials episode, I explore major depression, including its underlying biology and discuss science-based approaches to alleviate symptoms and improve mood. I describe the wide-ranging symptoms of depression and explain how key neurotransmitters, hormones, stress, genetics and inflammation contribute to its development and persistence. I also cover treatment options, from traditional classes of antidepressant medications to emerging therapies such as ketamine and psilocybin. Finally, I highlight lifestyle-based tools, including exercise, supplementation and dietary strategies that can help manage depressive symptoms and promote mental well-being.
