Temperature guide

How cold should a cold plunge be?

There is no single temperature that fits every person or goal. Temperature and time work together, so a colder session usually calls for a more conservative duration.

How Long to Cold Plunge

Start manageable

Build familiarity

Choose water that feels clearly cold without making the session a contest. Increase exposure gradually as you learn your response.

General wellbeing
