There doesn't seem to be any clear signal in the data. Maybe with a higher n than 10 a multimodal distribution might arise. At the very least I'd be interested to know if all the participants had done cold plunges before or if there is a mix of experienced practioners and newcomers in the cohort.

Some participants were doing cold plunges for the first time and others had done it before.

For participant 7 (who is an experienced cold plunger) we could see clear changes in their alpha power (dropping during the stroop task - attention & rising during resting state/cold plunge - being more relaxed)

thats my first thought as well. I hope to see a study with n in the range of 100s maybe when kernel headsets hit the market and reduced their cost

yep, this trial was to see if there were any neural effects. We plan to do a follow up study with a much larger cohort of people and also over many days. This will provide extra context for solid conclusions
