| 0:00.0 | Welcome to the Uberman Lab podcast where we discuss science and science-based tools for everyday life. |
| 0:08.8 | I'm Andrew Uberman and I'm a professor of neurobiology and |
| 0:12.4 | Ophthalmology at Stanford School of Medicine. Today my guest is Dr. Susanna Soberg. |
| 0:17.7 | Dr. Susanna Soberg completed her doctoral thesis work at the Center of Implamation and Metabolism and the Center for Physical Activity Research at the University of Copenhagen in Denmark. |
| 0:27.7 | Her research is focused on how deliberate cold exposure and deliberate heat exposure can be used to enhance human metabolism. |
| 0:35.0 | She is the first author of a seminal study which discovered the minimum thresholds for deliberate heat and deliberate cold exposure |
| 0:42.0 | for increasing brown fat thermogenesis, which is essentially a mode of increasing heat production and metabolism in the body, |
| 0:50.0 | and for establishing actionable protocols that can be used outside of the laboratory to improve metabolism and human health. |
| 0:57.5 | Dr. Soberg's research was published in the journal Cell Reports Metabolism in 2021. |
| 1:02.7 | Adding to a long and important history of research focusing on the role of cold and the role of heat in altering various aspects of the body's physiology, |
| 1:11.6 | including hormone health, metabolism, and changes in neurotransmitters such as dopamine and epinephrine. |
| 1:17.9 | In fact today's discussion with Dr. Soberg focuses on the role of deliberate heat and deliberate cold exposure on metabolism, |
| 1:23.9 | but it also includes discussion of the effects of cold and heat on things like neurotransmitter production, namely dopamine and epinephrine and norepinephrine, |
| 1:32.7 | the so-called catacole means, which strongly impact mood and metabolism. |
| 1:38.2 | In addition, Dr. Soberg answers many common questions about deliberate cold and deliberate heat exposure, |
| 1:43.4 | including for instance the difference between cold showers versus cold immersion up to the neck versus total body cold immersion, |
| 1:50.7 | including whether or not going back and forth between heat and cold changes fundamentally, the way that heat and cold impact, |
| 1:57.5 | the metabolism, hormones, and neurotransmitter production. |
| 2:00.5 | And we talk about almost every single nuance and variation on deliberate cold and deliberate heat exposure protocols |
| 2:07.1 | as it relates to the underlying science, in particular how cold receptors at the level of the skin are impacted versus cold reception |
| 2:15.2 | and perception at the level of the brain and how all of that impact systems of the brain embody relating to mental health, physical health, and performance. |
| 2:24.0 | Based on her scientific research and academic training, as well as her understanding and use of deliberate heat and deliberate cold exposure protocols, |
