Huberman Lab
Essentials: Breathing for Mental & Physical Health & Performance | Dr. Jack Feldman
· Summarized
Key takeaways
- Breathing is primarily controlled by the brainstem, specifically the pre-Bötzinger complex.
- Physiological sighs happen approximately every five minutes and are essential for lung health.
- Regulated breathing techniques can help manage anxiety and enhance emotional resilience.
- Breathing patterns can significantly influence the nervous system and emotional health.
- Magnesium L-threonate may support cognitive health and potentially help slow cognitive decline.
Summary
The Mechanics of Breathing and the Brain's Role
Andrew Huberman discusses the fundamental mechanics of breathing with Dr. Jack Feldman, who explains how respiration is driven by the diaphragm and specific neural circuits in the brainstem. The conversation delves into the function of the pre-Bötzinger complex as the primary respiratory rhythm generator, how air moves relative to pressure changes in the lungs, and variations between nasal and mouth breathing.
Physiological Sighs and Lung Maintenance
The podcast explores the concept of physiological sighs and their crucial role in maintaining lung health. Dr. Feldman shares that these deep breaths occur naturally about every five minutes and help prevent alveolar collapse, thereby ensuring effective oxygen exchange. He also recounts historical insights from mechanical ventilation techniques used for polio patients.
The Impact of Breathing on Mental States
An insightful discussion on how breathing patterns can significantly influence mental health and emotional resilience unfolds. Dr. Feldman emphasizes the importance of controlled breathing practices, including box breathing, in managing anxiety and improving overall cognitive function. He highlights key findings from rodent studies that connect slower breathing with reduced fear responses.
Breathing, Emotion, and Cognitive Control
Dr. Feldman illustrates the interconnectedness of breathing, emotional states, and cognitive processes, touching on the role of the olfactory system and the vagus nerve. He discusses how breathing patterns can modulate brain state and the potential therapeutic benefits of intentional breath practice for conditions like anxiety and depression.
The Role of Magnesium in Cognitive Health
The episode includes a discussion on the cognitive benefits of magnesium L-threonate, a compound that has shown promise in enhancing neuroplasticity and cognitive function. Dr. Feldman shares insights from studies showing cognitive improvements in subjects taking this specific form of magnesium, suggesting its potential for age-related cognitive decline.

Show notes
In this Huberman Lab Essentials episode, my guest is Dr. Jack Feldman, PhD, a Distinguished Professor of Neurobiology at the University of California, Los Angeles, and a leading expert in the science of breathing.
We explain the mechanics of breathing and the neural circuits that generate and regulate our breathing rhythm. We also discuss how breathing patterns profoundly influence mental states, including their role in reducing anxiety and enhancing emotional resilience. Dr. Feldman also shares practical tools, such as box breathing for daily performance and magnesium L-threonate supplementation to support cognitive health and longevity.
