Huberman Labs Protocol for Cold Thermogenesis
Dr. Andrew Huberman, a neuroscientist and professor at Stanford University, often discusses cold thermogenesis on his podcast, the Huberman Lab Podcast. His recommendations for cold exposure typically include:
- Frequency and Duration:
- Engage in cold exposure 1-3 times per week.
- Each session should last between 1-5 minutes depending on the individual’s tolerance and experience level.
- Temperature:
- Water temperature should be between 10°C to 15°C (50°F to 59°F).
- Protocol:
- Gradual acclimatization is key. Start with shorter durations and progressively increase the time spent in cold water.
- Ensure the body is completely submerged, if possible, for the most benefits.
- Breathe deeply and remain calm to help manage the body’s response to the cold.
- Benefits:
- Enhanced dopamine release, leading to improved mood and cognitive function.
- Improved resilience and stress management.
- Enhanced recovery and reduced inflammation in athletes.
Dr. Stacy Sims, a renowned exercise physiologist and nutrition scientist, emphasizes the importance of gender-specific approaches to cold exposure.
Her recommendations for cold plunges for females are as follows:
- Temperature:
- Women benefit most from cold water exposure at around 16°C (55-56°F).
- This temperature avoids the severe constriction and shutdown that can occur with colder temperatures.
- Frequency and Duration:
- Similar to general guidelines, cold plunges should be performed a few times a week.
- Duration can vary but should be enough to induce a noticeable response without causing excessive stress.
- Benefits:
- Enhanced dopamine response leading to better mood and overall well-being.
- Reduced risk of severe vasoconstriction, which can be more pronounced in women due to hormonal differences.
- Effective recovery tool when used at appropriate temperatures.
By following these protocols, both Huberman and Sims aim to maximize the benefits of cold exposure while minimizing potential risks, especially considering gender-specific responses to such stressors.

Huberman Lab Cold Protocol:
What are the best protocols for cold exposure?
Cold exposure protocols, as discussed by Andrew Huberman on the Huberman Lab, encompass a variety of practices for different goals such as enhancing mental health, improving physical performance, and increasing metabolism:
For Imposing Mental Stress and Building Resilience:
- Use an uncomfortable cold temperature for showers or cold immersions.
- Stay in for a duration of 30 seconds to 3 minutes.
- Repeat frequently within safety margins.
For Increasing Metabolism (Søberg Principle):
- End with cold exposure, forcing yourself to reheat naturally.
- Strive to reach the point of shivering.
- Consider alternating between cold exposure and air drying.
For Physical Performance and Recovery:
- Avoid cold immersions for up to four hours following strength/hypertrophy training if your goal is muscle growth and strength.
- For reducing soreness and improving training efficacy, shorter durations of cold exposure after training can be beneficial.
- Utilize cooling packs, ice baths, or cold showers, immediately or a few hours after training, depending on intensity.
For Enhanced Fat Loss:
- Engage in protocols that induce shivering through cooling and warming periods.
- Shifting from cold to a warmer environment back and forth is essential for this process.
Dr. Huberman emphasizes that the specific temperature and duration may vary between individuals based on tolerance and adaptation to cold and that safety should always be the priority when experimenting with cold exposure. Notably, the experience of cold and the response to it can be subjective, and hence, protocols may need personal adaptation 1 2 3 4 5 6 7.

What are the heat protocols for men and women?
Here’s a summary of the podcast segment featuring Dr. Stacy Sims on Dr. Andrew Huberman’s podcast:
- Cold Exposure Timing:
- Deliberate cold exposure (e.g., submersion up to the neck) post-resistance training can attenuate inflammation but may also inhibit strength and hypertrophy gains.
- It is advised to avoid cold exposure within eight hours of resistance training aimed at strength and hypertrophy.
- Cold exposure might have performance-enhancing effects if done before training.
- Heat Exposure Timing:
- Heat exposure (e.g., sauna) is beneficial after resistance training.
- It helps extend the training stimulus through vasodilation and promotes greater blood volume improvements.
- Hydration and Rehydration:
- After resistance training and sauna use, slow rehydration is important.
- Dehydration during training stimulates increased red blood cell production and plasma volume, acting as a blood volume expander.
- Protocol for Performance Enhancement:
- Post-resistance training: Drink 8-16 ounces of water with a pinch of salt.
- Follow with up to 30 minutes in the sauna, ensuring proper hydration.
- Applicability:
- The discussed protocol is applicable to both men and women.
Here’s a summary of using sauna exposure post-resistance and cardio training to improve performance:
- Post-Resistance Training:
- Sauna exposure can enhance performance by extending the training stimulus.
- It promotes vasodilation and blood volume improvements.
- Sauna use after resistance training helps with recovery and may improve overall performance.
- Post-Cardio Training:
- Sauna exposure is also beneficial after cardio workouts.
- The passive dehydration from cardio (where you can’t fully rehydrate during exercise) is complemented by sauna use.
- Sauna extends the training stimulus and encourages increased blood volume as the body responds to dehydration.
- General Benefits:
- Elevated heart rate from sauna use adds an extra layer of stress that can further stimulate cardiovascular and overall fitness improvements.
- Enhances the body’s response to training by boosting blood volume and recovery.
Here’s a detailed explanation of the mechanism of action for using sauna exposure post-resistance and cardio training to improve performance:
- Passive Dehydration:
- During training (both resistance and cardio), the body loses fluids through sweat, leading to passive dehydration. This type of dehydration occurs naturally and cannot be completely avoided during exercise.
- Sauna Exposure Mechanism:
- Extended Training Stimulus: When you enter the sauna after training, the elevated heart rate and heat stress simulate additional exercise conditions.
- This keeps the cardiovascular system engaged and extends the benefits of the initial training.
- Stress Response: The sauna introduces an additional stressor (heat and dehydration) to the body.
- This stress further stimulates physiological responses that enhance performance.
- Increased Blood Volume: The body responds to this added stress by increasing blood volume.
- This response is mediated by the need to compensate for the dehydration and maintain adequate blood circulation.
- Improved Recovery: Enhanced blood volume can aid in faster recovery and better nutrient delivery to muscles, potentially leading to improved performance in subsequent workouts.
- Performance Benefits:
- Cardiovascular Improvements: The additional cardiovascular stress from the sauna helps improve overall heart and circulatory system performance.
- Enhanced Adaptation: By extending the training stimulus and stressing the body further, the sauna can help boost adaptations and improvements in fitness and endurance.
Here’s a detailed explanation of the mechanism of action and scientific backing for using sauna exposure post-training to improve performance:
1. Extended Training Stimulus
- Mechanism of Action:
- After training, entering a sauna maintains an elevated heart rate due to the heat stress. This mimics the cardiovascular demands of exercise, keeping the cardiovascular system engaged even after the workout has ended.
- Scientific Backing:
- Cardiovascular Adaptations: Research shows that heat exposure can induce cardiovascular adaptations similar to those from exercise. For example, a study published in Journal of Applied Physiology found that regular sauna use can lead to improved cardiovascular function and endurance (Laukkanen et al., 2015).
- Heart Rate and Heat Stress: Elevated heart rate in the sauna is comparable to the cardiovascular response during moderate exercise, leading to additional cardiovascular training benefits (Kukkonen-Harjula et al., 2007).
2. Stress Response
- Mechanism of Action:
- The sauna introduces additional stress through heat and dehydration, which further challenges the body’s physiological systems. This added stress prompts a stress response that can enhance overall performance and adaptation.
- Scientific Backing:
- Heat Stress and Hormonal Response: Heat exposure activates stress pathways, including the release of heat shock proteins and hormones like cortisol, which help the body adapt to stress and improve resilience (Mayer et al., 2013).
- Dehydration Effects: Passive dehydration from sauna use can enhance the body’s adaptive responses. Studies indicate that dehydration stimulates erythropoiesis (red blood cell production) and enhances plasma volume, which supports better cardiovascular and performance outcomes (Gonzalez-Alonso et al., 1999).
3. Increased Blood Volume
- Mechanism of Action:
- The stress from heat exposure and dehydration prompts the body to increase blood volume to maintain circulation and compensate for fluid loss. This process helps in sustaining adequate blood flow and nutrient delivery.
- Scientific Backing:
- Blood Volume Expansion: Sauna use has been shown to increase blood plasma volume, which can help improve blood circulation and oxygen delivery to muscles (Biering-Sorensen et al., 2008).
- Plasma Volume and Recovery: An increase in plasma volume supports better recovery by enhancing the transport of nutrients and removal of metabolic waste products (Gonzalez-Alonso et al., 1999).
4. Improved Recovery
- Mechanism of Action:
- Enhanced blood volume and circulation from sauna use improve the delivery of nutrients and oxygen to muscles, aiding in faster recovery and preparation for subsequent workouts.
- Scientific Backing:
- Recovery and Performance: Improved blood flow and increased plasma volume support muscle repair and growth. Research supports that heat exposure can enhance muscle recovery by boosting blood circulation and reducing muscle soreness (Laukkanen et al., 2018).
