Two behaviors that I feel are super common and have a noticeable impact on stress, HR, and performance are missing from the journal. Which is sun-tanning and consuming pre-workout.
Tanning or sun-exposure subjects the body to heat and UV rays which have potential positive and negative physical effects with would be important to analyze.
Pre-workout or a “pump” that increases nitric oxide production would also be great to track to see if it improves performance in both the short and long term or if it has any detrimental effects. Caffeine is already in the journal but I feel that is very different from the effects of a NO supplement.
I hope you could add them in the near future!
