Hi everyone! :) I built Cold Plunge Time after getting into cold plunging and realizing I was constantly guessing how long to stay in the water depending on the temperature. Sometimes the difference between 40°F and 50°F feels huge, but most advice online is just “stay in for a few minutes.” So I made a simple calculator that estimates plunge time based on water temperature and experience level. I also added a breathing timer and a simple streak tracker because I noticed consistency was the hardest part. I also did some researching and hoped to answer common yet tricky-to-find answers for cold plunge questions. It’s still evolving, and I’d really love feedback from people who cold plunge, sauna, or experiment with cold exposure. If there’s anything you think would make it more useful, I'd love to hear it. Thank you!
