Andrew Huberman and the Sauna: A Deep Dive

TLDR: Andrew Huberman, a renowned neuroscientist, advocates for the use of saunas due to their potential benefits for brain function, mood, and overall health. Regular sauna use has been linked to improved cardiovascular health, enhanced immune function, reduced stress and anxiety, and even increased longevity. Huberman suggests that the heat stress from saunas triggers physiological responses that can promote neuroplasticity and benefit the brain and body. To incorporate saunas into your routine, start slow, stay hydrated, and gradually increase your sauna time as your body adapts to the heat.

The world of wellness is vast and varied, with countless practices and products promising to improve our health and wellbeing. One practice that has been gaining attention recently is the use of saunas, particularly as advocated by renowned neuroscientist Andrew Huberman. But what exactly is the science behind this, and how can we incorporate it into our own routines? Let's dive in.

Who is Andrew Huberman?

Before we delve into the sauna, let's first get to know the man behind the science.

His Background and Achievements

Andrew Huberman is a distinguished neuroscientist and tenured professor at Stanford University School of Medicine. He has made significant contributions to the fields of brain development, brain plasticity, and neural regeneration and repair. Huberman has published over 100 peer-reviewed articles in top scientific journals and has received numerous awards for his research, including the McKnight Foundation Neuroscience Scholar Award and the Pew Biomedical Scholar Award [1].

His Work in Neuroscience

Huberman's work primarily focuses on the brain's ability to change and adapt, a concept known as neuroplasticity. His research has provided valuable insights into how we can harness our brain's plasticity to improve our cognitive and physical performance, manage stress, and enhance our overall wellbeing. Huberman's lab at Stanford investigates the neural circuits that control vision, as well as the mechanisms of brain plasticity and regeneration [2].

The Science of Saunas

Now, let's turn our attention to the sauna, a centuries-old practice that has been a staple in many cultures around the world.

The Basics of Saunas

A sauna is a small room or building designed to induce sweating and increase heart rate through the use of heat. This can be achieved through various means, such as wood-burning stoves, electric heaters, or infrared lamps. The temperature in a traditional Finnish sauna typically ranges from 80°C to 100°C (176°F to 212°F), with a humidity level of 10% to 20% [3].

Health Benefits of Saunas

Regular sauna use has been linked to a variety of health benefits, including improved cardiovascular health, enhanced immune function, and reduced stress and anxiety. Some studies even suggest that it can increase longevity. A large prospective study in Finland found that frequent sauna bathing (4-7 times per week) was associated with a reduced risk of cardiovascular disease and all-cause mortality [4].

Andrew Huberman's Take on Saunas

As a neuroscientist, Andrew Huberman looks at saunas through a unique lens, focusing on their impact on our brain and nervous system. Huberman suggests that the heat stress from sauna use can trigger a series of physiological responses that can enhance brain function, improve mood, and even promote neuroplasticity. This includes the release of heat shock proteins, endorphins, and norepinephrine, all of which have beneficial effects on our brain and body [5].

Huberman's Personal Sauna Routine

Huberman is a regular sauna user himself, incorporating it into his daily routine. He typically spends 20-30 minutes in the sauna, followed by a cold plunge to stimulate his nervous system and promote recovery. This alternation between hot and cold exposure, known as contrast therapy, has been shown to have additional benefits for the cardiovascular system and muscle recovery [6].

The Neuroscience Behind Sauna Use

According to Huberman, the heat stress from sauna use triggers a series of physiological responses that can enhance brain function, improve mood, and even promote neuroplasticity. This includes the release of heat shock proteins, endorphins, and norepinephrine, all of which have beneficial effects on our brain and body. Heat shock proteins, in particular, have been shown to protect neurons from damage and promote the growth of new neural connections [7].

How to Incorporate Saunas into Your Routine

Inspired to give saunas a try? Here's how you can get started.

Finding the Right Sauna

The first step is to find a sauna that suits your needs and preferences. This could be a traditional Finnish sauna warmed by a wood-fire, an infrared sauna powered by new technology, or even a convenient portable sauna for home use. Ideally, the temperature of the sauna would fall between 80°C-100°C, however it's crucial to listen to your body. If these temperatures are overwhelming then don't be afraid to alter temperatures and determine what temperature is most comfortable and effective for you.

Creating a Sauna Routine

Start slow and gradually increase your sauna time as your body adapts to the heat. While it is recommended that you start by staying in the sauna for 5-20 minutes, don't feel pressured to meet this target straight away. Remember to stay hydrated and listen to your body. It's not a competition, but a practice of self-care. Huberman suggests starting with 2-3 sauna sessions per week, and gradually increasing to 4-7 sessions per week for optimal benefits [5].

Staying Hydrated is Essential

Expect to sweat an awful lot in a sauna session, which means you will lose not only a significant amount of water, but also a number of important electrolytes. This is why it's extremely important to be well hydrated before heading into the sauna, as well as replenishing the water deficit afterwards. Dr. Huberman's recommendations are to drink at least 16oz (around 500ml) of water for every 10 minutes spent inside the sauna. It's also a good idea to replenish electrolytes after a sauna session, either through a balanced meal or an electrolyte supplement.

Common Misconceptions About Saunas

Despite their benefits, saunas are often misunderstood. Let's clear up some common misconceptions.

Debunking Sauna Myths

One common myth is that saunas are dangerous for people with heart conditions. While it's always important to consult with a doctor before starting any new health practice, research has shown that saunas can actually improve cardiovascular health. A systematic review and meta-analysis found that regular sauna bathing was associated with a reduced risk of fatal cardiovascular events and all-cause mortality [8].

The Science Behind the Myths

The key is understanding the body's response to heat stress and ensuring that you're using the sauna safely and effectively. Remember, it's about wellness, not endurance. If you have any pre-existing health conditions, it's always best to consult with your doctor before starting a sauna routine.

Conclusion

Andrew Huberman's insights into the neuroscience of saunas provide a fascinating perspective on this ancient practice. Whether you're a seasoned sauna-goer or a curious newcomer, there's much to gain from incorporating this practice into your wellness routine. By understanding the science behind saunas and following Huberman's guidance on safe and effective use, you can harness the power of heat stress to improve your brain function, mood, and overall health.
