Cold plunge skeptic after 2 months of data in Austin

I thought the whole cold plunge thing was bro science until I tracked my sleep with a cheap Oura knockoff for 60 days. My deep sleep jumped from 1.2 hours to 1.8 hours average on days I did 3 minutes at 50F. Anyone else see similar numbers or is my thermometer just off?

Figure out if your sleep tracker is even accurate before crediting the cold water. Those cheap rings are known to overestimate deep sleep by a lot, especially after any big change in your routine. Besides, 50F in Austin in summer is a pretty easy plunge, so maybe you're just sleeping better because you're not sweating all night.
