What is cold exposure protocol?

Andrew Huberman outlines several protocols for cold exposure, tailored to different goals such as fat loss, mental toughness, and dopamine increase. Key points include:

1. General Protocol:

   • Use accessible cold sources like cold showers, ice baths, or natural cold water (rivers, oceans) to induce shivering.
   • Alternate between cold and slightly warmer environments to maximize shivering, which promotes fat loss and resilience 1.

2. Mental Health and Resilience:

   • Deliberate cold exposure increases norepinephrine and epinephrine, similar to stress responses, helping build mental toughness.
   • A protocol involves finding a cold, uncomfortable temperature and immersing for a set duration to build resilience and maintain mental clarity during stress 2.

3. Dopamine Increase:

   • Short exposures (1-10 minutes) to cold water (around 50-55°F or even colder) can significantly increase dopamine and epinephrine.
   • The temperature should be uncomfortable but safe. A brief cold shower can also suffice 3.

4. Post-Training Recovery:

   • Cold exposure immediately after high-intensity exercise can reduce muscle soreness and improve recovery, particularly for endurance training.
   • Recommendations vary, but 1-5 minute exposures to very cold water are beneficial. Avoid cold exposure within four hours of strength/hypertrophy training to prevent inhibiting muscle growth 4 5.

Make sure to progress gradually, consult a physician before starting new protocols, and prioritize safety during cold exposure 6.
