In this podcast I discuss some of the mechanisms by which chronic stress (and rumination) affect the brain and brain aging, the gut and inflammation, the immune system, and biological aging through acceleration of telomere shortening. I talk about how meditation can buffer these negative effects of stress and improve cognitive performance, brain aging and biological aging in general.

In this episode Rhonda talks about how heat stress from using the sauna makes the body more resilient to the stresses of aging, possible reasons why one study associated sauna use with up to a 40% lower all-cause mortality as well as a 50% lower cardiovascular disease related mortality, how it enhances athletic endurance, staves off muscle atrophy, improves regrowth of muscle after disuse, and some of the profound effects on the brain, including the growth of new brain cells, improvement in focus, learning, and memory, and even potentially ameliorating depression and anxiety. She also talks about how BPA, PCBs, phthalates, and other metals are excreted through sweat. In addition, she addresses some practical applications like temperature and duration in the sauna, the difference between a dry, wet and infrared sauna, sauna timing, as well as other forms of heat stress such as steam showers, hot baths, and hot yoga.

Dr. Justin Sonnenburg is an associate professor of microbiology and immunology at Stanford and Dr. Erica Sonnenburg is a senior research scientist in the Sonnenburg lab where they research many aspects the interaction between diet with the 100 trillion or so bacteria in the gut (specifically the colon) and how this impacts the health of the host (which in this case is a laboratory research mouse). In this episode we discuss the pivotal role fiber plays in fueling good bacteria in the gut to produce compounds that regulate the immune system including increasing the number of T regulatory cells, which are specialized types of immune cells that keep the immune system in check and prevent autoimmune responses, and how these compounds also increase other types of blood cells in the body in a process known as hematopoiesis. We also talk about how the lack of fiber in the typical American diet actually starves these good bacteria of their food. This has an effect not only on the immune system and autoimmune diseases but also results in the breakdown of the gut barrier, which leads to widespread inflammation and inflammatory diseases. Lastly, in this podcast, Dr. Erica Sonnenburg talks about how C-sections, have a negative effect on the infant’s gut due to the lack of exposure to bacteria present in the mother’s vaginal canal, and how the use of formula deprives the infant not only from the good bacteria present in Mom’s gut but also from special carbohydrates in breast milk that are good for the infant gut flora known as HMOs or human milk oligosaccharides.
