7 day of cold Shower in Winter – Before and After HRV / Blood Sugar / Reaction time

Preamble

I am in France now, it’s around 7 C in the morning.

I will be recording my HRV, and reaction time before and after my cold showers for 7 days.

The shower will start with hot water, I will then stay under cold water for 5 minutes.

For my HRV, I will use the app FLOWT

For my reaction time, I will use this website

Here is the data:
