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:
|Day||Before HRV(RMSSD)||After HRV(RMSSD)||Before Reaction Time||After Reaction Time|
Even if the dataset is very small, it is very confirming the hypothesis of cold-shower having immediate benefits on me.
