What's the best protocol for doing a cold plunge to maximize performance and health?

Andrew Huberman provides several insights on how to maximize performance and health through cold exposure. Here is a summarized protocol based on his various discussions on the topic:

1. Timing: It's best to do cold exposures early in the day, such as in the morning, to benefit from increased alertness and mood-enhancing effects that last for hours. Avoid cold exposure within six hours after strength training sessions, as it can impair muscle growth and recovery 1 2.

2. Duration and Temperature:

   • Short bursts of cold exposure, ideally between 30 seconds to 2 minutes, are effective for boosting dopamine levels 2.
   • The water temperature for short durations should be between 37°F to 55°F. Start with warmer temperatures and gradually move to colder ones as you build tolerance 1 3.

3. Safety and Practicality:

   • Beginners can start with temperatures around 55°F to 60°F and reduce the temperature over time. More experienced individuals can aim for 45°F to 50°F 4.
   • Always prioritize safety: have someone oversee your first exposure if possible, avoid deep breathing or breath-holding techniques beforehand to prevent accidents 4.

4. Types of Cold Exposure:

   • Use methods such as cold showers, ice baths, or cold plunges. Each method can have varying intensities and durations, with short and colder exposures being as effective as longer, milder conditions for catecholamine release 5 6.

Cold exposure boosts catecholamines (like dopamine and adrenaline), improving alertness, mood, and resilience against stress. Always approach cold exposure gradually and adjust according to personal comfort and safety levels 7 8.
