Welcome to the Huberman Lab Podcast, where Andrew Huberman discusses the science of heat and its effects on health. Heat is a powerful stimulus that influences metabolism and cognition. Properly applied heat can enhance brain function rather than impair it. The episode covers mechanisms of heating, tools like saunas, and the emerging science of local heating for tissue improvement. A recent study published in the journal Cell demonstrates that local heating of skin and fat can convert white fat into beige fat, which is more metabolically active. White fat serves as a fuel reserve, while beige and brown fat, rich in mitochondria, help burn white fat and increase metabolism. This research stems from understanding how burns affect biology, leading to new tools for combating obesity and metabolic disorders. Huberman announces a partnership with Momentous Supplements to provide high-quality supplements based on scientific research. He also mentions upcoming live events in Seattle and Portland, where he will discuss science-based tools and answer audience questions. The podcast emphasizes that heating occurs in two ways: from external sources and internally generated heat. The body has two temperatures: the core (internal) and the shell (skin surface). The brain regulates these temperatures, akin to a thermostat, sending signals to heat up or cool down. Understanding this balance is crucial for optimizing health through heat exposure. Deliberate heat exposure, such as sauna use, can significantly improve health outcomes. A 2018 study found that regular sauna use reduces cardiovascular mortality. Participants who used saunas two to three times a week had a 27% lower risk of cardiovascular events compared to those who used them once a week. More frequent sauna use (four to seven times a week) correlated with a 50% reduction in mortality risk. Sauna temperatures typically range from 80 to 100 degrees Celsius (176 to 212 degrees Fahrenheit), with sessions lasting five to 20 minutes. Regular sauna use can mimic cardiovascular exercise, increasing heart rate and blood flow. Heat exposure also influences hormone levels, including cortisol and growth hormone. A study showed that sauna sessions could increase growth hormone levels significantly, with a 16-fold increase observed after specific protocols. Huberman discusses the importance of timing sauna sessions, suggesting they be done later in the day to promote better sleep. He advises against excessive heat exposure, as it can lead to hyperthermia. The episode also highlights the role of heat shock proteins in protecting cells from damage and the potential for local heating to enhance metabolism. Local hyperthermia therapy, which involves heating specific skin areas, can convert white fat to beige fat, increasing overall metabolism. This process is linked to mechanisms involving UCP1 and heat shock factor one (HSF1), which regulate glucose and lipid metabolism. In summary, deliberate heat exposure through saunas or local heating can improve health, enhance mood, and potentially increase longevity. Huberman encourages listeners to explore these methods while being mindful of safety and individual tolerance levels.
