This episode I am joined by Dr. Craig Heller, Professor of Biology at Stanford University and world expert on the science of temperature regulation. We discuss how the body and brain maintain temperature under different conditions and how most everyone uses the wrong approach to cool off or heat up. Dr. Heller teaches us the best ways and in doing so, explains how to offset hyperthermia and hypothermia. He also explains how we can use the precise timing and location of cooling on our body to greatly enhance endurance and weight training performance. He describes how cooling technology discovered and engineered in his laboratory has led to a tripling of anaerobic (weight training) performance and allowed endurance athletes to run further and faster, as well as to eliminate delayed onset muscle soreness. Dr. Heller explains how heat impairs muscular and mental performance, and how to cool the brain to reduce inflammation and to enhance sleep and cognition. We discuss how anyone can apply these principles for themselves, even their dogs! Our conversation includes both many practical tools and mechanistic science.

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.
- Today I have the pleasure of introducing Dr. Craig Heller as my guest on the Huberman Lab Podcast.
Professor of biology and neurosciences at Stanford. His laboratory works on a range of topics, including thermal regulation, down syndrome, and circadian rhythms.
Today, we talk about thermal regulation, how the body heats and cools itself and maintains what we call homeostasis, which is an equilibrium of processes that keeps our...
Neurons healthy, our organs functioning well. And as Dr. Heller teaches us, thermoregulation can be leveraged in order to greatly increase our performance in athletics and mental performance as well. Learning to control your core body temperature is one of the most, if not the most powerful thing that you can do to optimize mental and physical performance.
Regardless of the environment that you're in. He also dispels many common myths about heating and cooling the body, including the...
That putting a cold pack on your head or neck is the optimal way to cool down quickly. And in fact, as Dr. Heller tells us, it actually can be counterproductive and lead to hyperthermia.
It's a fascinating conversation from which I learned a tremendous amount of new information and we...
We can even get into the other incredibly interesting work that Dr. Heller does on Down syndrome and circadian rhythms and sleep. So we hope to have him back in the future to.
Those topics. As you'll soon see, Dr. Heller is a wealth of knowledge on all things, human physiology, biology, and human performance. It's no surprise then that he's been.
Chair of the biology department at Stanford for many years, as well as director of the human biology program.
In human biology and how to improve your performance in any context or setting, athletic or otherwise, I think you'll very much enjoy today's conversation.
- Before we begin, I'd like to emphasize that this podcast is separate from my teaching and research roles at Stanford. It is however, part of my desire and effort to bring zero cost to consumer information about science and science related tools to the general public. In keeping with that theme, I'd like to thank the sponsors of today's podcast.
Our first sponsor is Athletic Greens. Athletic Greens is an all-in-one vitamin mineral probiotic drink. I've been taking Athletic Greens since 2000.
So I'm delighted that they're sponsoring the podcast. The reason I started taking Athletic Greens
Of collard greens once or twice a day is that it helps me cover all of my basic nutritional needs. It makes up for any deficiencies that.
I might have. In addition, it has probiotics, which are vital for microbiome health. I've done a couple of episodes now on the so-called gut microbiome.
And the ways in which the microbiome interacts with your immune system, with your brain to regulate mood and essentially...
Every biological system relevant to health throughout your brain and body. With that, let it greens, I get the vitamins I need, the minerals I need, and the probiotics to support my microbiome.
- Try Athletic Greens, you can go to athleticgreens.com/huberman and claim a special offer.
Five free travel packs, plus a year's supply of vitamin D3K2.
Ton of data now showing that vitamin D3 is essential for various aspects of our brain and body health. Even if we're getting a lot of sunshine, many of us are still deficient in vitamin D3.
And K2 is also important because it regulates things like cardiovascular function, calcium in the body, and so on.
Go to athleticgreens.com/huberman to claim the special offer of the five free travel packs and the year supply of vitamin D3 K2. Today's episode is also brought to us by Element.
Element is an electrolyte drink that has everything you need and nothing you don't. That means the exact ratios of electrolytes are an element.
And those are sodium, magnesium, and potassium, but it has no sugar. I've talked many times before on this podcast about the key role of hydration and electrolytes for nerve cell function, neuron function, as well as the function of all the cells
in organ systems of the body. If we have sodium, magnesium, and potassium present in the proper ratios, all of those cells function properly and all our bodily systems can be optimized. If the electrolytes are not present and if hydration is low.
We simply can't think as well as we would otherwise. Our mood is off, hormone systems go off, our ability to get into physical action, to engage in endurance and strength and all sorts of other things is.
So with Element, you can make sure that you're staying on top of your hydration and that you're getting the proper ratios of electrolytes. If you'd like to try Element, you can.
Go to drink element that's lmnt.com/huberman, and you'll get a free element sample pack with your purchase.
Again, if you want to try Element, you can go to elementlmnt.com/huberman. Today's episode is also brought to us by Waking Up. Waking Up is a meditation app.
That includes hundreds of meditation programs, mindfulness trainings, yoga nidra sessions, and NSDR, non-sleep deep rest protocol.
