Cold Plunge Temperature Guide
What temperature should your cold plunge be? A complete guide.
Temperature is one of the most common questions for cold plunge beginners. The right temperature depends on your experience level, goals, and personal tolerance.
For beginners, start between 60-68°F (15-20°C). This is cold enough to trigger the cold shock response and provide benefits, but manageable for those new to cold exposure. Spend 1-3 minutes at this temperature.
Once comfortable with beginner temperatures, progress to 50-59°F (10-15°C). This is where most regular cold plungers operate. Sessions of 2-5 minutes at this range provide significant benefits without extreme discomfort.
Experienced practitioners often plunge at 38-45°F (3-7°C). At these temperatures, sessions are typically shorter (2-4 minutes). This range provides maximum cold shock and hormone response but requires significant adaptation.
If you have a chiller, set it to maintain a consistent temperature. Without a chiller, water temperature will fluctuate based on ambient conditions. In summer, you may need ice to reach desired temperatures. In winter, outdoor tubs may get colder than intended.
Research suggests the total weekly cold exposure matters more than single-session extremes. 11 minutes per week at moderate temperatures (50-59°F) may be more beneficial than occasional extreme cold sessions.
Frequently Asked Questions
50-59°F (10-15°C) is the sweet spot for most people. Cold enough for benefits, manageable for 2-5 minute sessions. Beginners should start warmer (60-68°F).
No. Extremely cold water (below 40°F) increases risks and doesn't necessarily provide more benefits. Consistency and total weekly exposure matter more than extreme temperatures.
Use a waterproof thermometer or a cold plunge with a built-in display. Check temperature before entering. Water can stratify, so stir before measuring for accuracy.
