In a recent episode of the Huberman Lab Podcast, hosted by Dr. Andrew Huberman, a deep dive was conducted into the effects of deliberate cold exposure on health and performance, with a focus on athletic performance and recovery. The discussion highlighted both biological mechanisms and practical protocols for utilizing cold exposure to enhance physical capacities and recovery processes. This article summarizes key points from this discussion and provides insights into the application of cold exposure in athletic contexts.
Understanding Cold Exposure
Cold exposure can stimulate a powerful physiological response in the body. As Dr. Huberman explains, exposure to cold increases the release of catecholamines such as norepinephrine and epinephrine. These chemicals are associated with heightened alertness, focus, and mood improvement when managed in appropriate conditions (Effects of lifestyle choices on neurotransmitter levels) ([01:08:15]).
Athletic Performance and Recovery
Enhancing Endurance and Strength
Dr. Huberman outlines a systematic review, which indicates that cold water immersion following high-intensity exercise can be an effective recovery tool. It improves muscular power, reduces muscle soreness, and enhances perceived recovery in athletes. Interestingly, cold exposure post-exercise may boost performance in subsequent sessions by reducing inflammation and enabling quicker recovery (Importance of recovery in muscle growth and training) ([01:39:37]).
Protocols for Cold Exposure
-
Timing: For athletes whose primary goals include hypertrophy and strength training, Dr. Huberman advises caution with immediate cold exposure following such workouts, suggesting a gap of four hours to ensure optimal training benefits (Science-based exercise optimization). For endurance training and general recovery, immediate cold exposure can be advantageous (Fitness protocols for endurance and strength) ([01:38:00]).

Modes of Cold Exposure: While cold water immersion is highlighted as particularly effective, cold showers and other forms of cold therapy can also be beneficial, provided they create a sense of discomfort that is safely manageable. Structured protocols like cold immersion for short durations at lower temperatures have been shown to improve recovery outcomes more effectively than passive recovery alone ([01:39:37]).
Biological Mechanisms
Reducing Inflammation
Deliberate cold exposure reduces inflammation by decreasing the levels of pro-inflammatory cytokines while increasing the presence of anti-inflammatory cytokines. This biological response supports muscle recovery and helps in managing soreness after intense physical exertion (Role of inflammation in chronic disease) ([01:46:29]).
Glabrous Skin Cooling
An interesting aspect of cold exposure in athletic contexts is the focus on cooling specific areas of the body known as glabrous skin—palms, soles, and the upper face. Cooling these areas efficiently reduces core body temperature, significantly enhancing physical performance and endurance by allowing greater work volume and extending time to fatigue (Thermoregulation and human performance) ([01:48:01]).
Glabrous Skin Cooling
Cooling the palms alone can radically reduce core body temperature, enabling extended workout sessions and reducing onset muscle soreness. This phenomenon is attributed to the unique vasculature present just beneath these skin areas.
Recommendations
To optimize the benefits of cold exposure:
- Integrate into Routine: For general recovery, integrate cold exposure post-exercise regularly, aiming for a cumulative total of around 11 minutes weekly.
- Explore Timing and Techniques: Depending on training goals, adjust the timing of cold exposure relative to workout sessions, particularly for strength-focused athletes (Training program structure and periodization).
- Consider Skin Cooling: Utilize cooling of glabrous skin areas for enhanced endurance and recovery, especially under high stress or volume training programs (Understanding the energy systems for endurance).
The discussion led by Dr. Huberman establishes a clear foundation for the use of cold exposure as an effective strategy for enhancing athletic performance and recovery through physiological and neurochemical pathways. Whether through immersion or targeted skin cooling, cold exposure can be a robust addition to an athlete’s regimen.
