LIVE EVENT Q&A: Dr. Andrew Huberman at the Brisbane Convention & Exhibition Centre

Welcome to the Huberman Lab podcast, where we discuss science and science-based tools for everyday life. I'm Andrew Huberman, and I'm a professor of neurobiology and ophthalmology at Stanford School of Medicine. Recently, the Huberman Lab podcast hosted a live event at the Great Hall in Brisbane, Australia. The event was called The Brain Body Contract, and featured a lecture followed by a question-and-answer session with the audience. We wanted to make the question-and-answer session available to everyone, regardless if you could attend. I also would like to thank the sponsors for the event. They are Eight Sleep and AG1. Eight Sleep makes smart mattress covers with cooling, heating, and sleep tracking capacity. Now, I've spoken many times before on this podcast about the fact that sleep is the critical foundation for mental health, physical health, and performance. Now, one of the key things to getting the best possible night's sleep is to control the temperature of your sleeping environment, and that's because in order to fall and stay deeply asleep, your body temperature actually needs to drop by about one to three degrees, and in order to wake up feeling refreshed and alert, your body temperature actually has to increase by about one to three degrees. Eight Sleep mattress covers make it extremely easy to control the temperature of your sleeping environment, and thereby to control your core body temperature so that you fall and stay deeply asleep and wake up feeling your absolute best. I've been sleeping on an Eight Sleep mattress cover for about three years now, and it has completely transformed the quality of my sleep for the better. Eight Sleep recently launched their newest generation of pod cover, the Pod 4 Ultra. The Pod 4 cover has improved cooling and heating capacity, higher fidelity sleep tracking technology, and the Pod 4 cover has snoring detection that will automatically lift your head a few degrees to improve airflow and stop your snoring. If you'd like to try an Eight Sleep mattress cover, you can go to eight sleep.com/huberman to save $350 off their Pod 4 Ultra. Eight Sleep currently ships to the USA, Canada, UK, select countries in the EU and Australia. Again, that's eight sleep.com/huberman. The other live event sponsor, AG1, is a vitamin mineral probiotic drink that also contains adaptogens and other critical micronutrients. I've been taking AG1 daily since 2012, so I'm delighted that they decided to sponsor the live event. I started taking AG1, and I still take AG1 once or twice a day because it gives me vitamins and minerals that I might not be getting enough of from whole foods that I eat, as well as adaptogens and micronutrients. Those adaptogens and micronutrients are really critical, because even though I strive to eat most of my foods from unprocessed or minimally processed whole foods, it's often hard to do so, especially when I'm traveling and especially when I'm busy. So by drinking a packet of AG1 in the morning, and oftentimes also again in the afternoon or evening, I'm ensuring that I'm getting everything I need. I'm covering all of my foundational nutritional needs. And I, like so many other people that take AG1 regularly, just report feeling better. And that shouldn't be surprising because it supports gut health and, of course, gut health supports immune system health and brain health, and it's supporting a ton of different cellular and organ processes that all interact with one another. So while certain supplements are really directed towards one specific outcome, like sleeping better or being more alert, AG1 really is foundational nutritional support. It's really designed to support all of the systems of your brain and body that relate to mental health and physical health. If you'd like to try AG1, you can go to drinkag1.com/huberman to claim a special offer. They'll give you five free travel packs with your order, plus a year supply of vitamin D3 K2. Again, that's drinkag1.com/huberman. And now for the live event at the Great Hall in Brisbane, Australia. What are my thoughts on nicotine? Um, nicotine causes cancer when it's consumed in the form of smoking, vaping, dipping or snuffing. So don't do that. Um, there's a debate now about vaping. Is it bad? Is it good? It's bad. Um, it-
