Cold side . 6 minute read
How long should you really stay in a cold plunge?
Every week someone climbs out of the 45 F pool, checks the clock and asks if two minutes was enough. Then someone else asks if it was too much. The honest answer to both: it was probably fine, and probably more than you needed.
The short answer
For almost everyone, thirty seconds to two minutes per round is plenty. Three rounds in one visit adds up to a few minutes of cold in total. That is a full practice. Anything past three minutes at our coldest pool is mostly a test of stubbornness.
Thirty seconds, three times, beats three minutes once.
Why the first thirty seconds matter most
When you hit cold water you gasp, your heart jumps and your breathing gets fast. That is the cold shock reflex. It usually fades in about half a minute if you breathe out slowly. So the first thirty seconds is where all the hard work, and most of the feeling, lives. After that, it gets calmer, and the extra minutes add less than people think.
How to build up without making it a contest
- Change one thing per visit: a little longer, or a little colder, never both.
- Count breaths, not seconds. Ten slow exhales is about thirty seconds.
- Stop while it still feels good. Leaving wanting more is the whole point.
When to get out early
Numb fingers, shivering you cannot control, or a feeling that something is off. Get out, wrap up, sit in the lounge. Our science page goes into what the research does and does not say, and the plunge page explains the three pools.
