I know historically that I have a way lower HRV score based on other people my age - I'm pretty sure that's bad. In the past exercise didn't have the effect on it it should, but I need to dive deeper into this.

I wear an Apple Watch pretty much constantly, and I decided to see what Claude had to say if I uploaded my Apple Health Data. So I went ahead and exported it from the Health app on my iPhone, and tried uploading it to Claude - but at 175mb, it was bigger than the limit of 35mb they allow (or whatever it is - i later found out the desktop app does not have this restriction). Claude automatically suggested it could write me a ruby script that could parse the xml file and give me a csv with the data I needed, it even gave me an option to just extract for the last X months. So I decided we would do the last 12 months, and it gave me a .csv file.

I uploaded that in a Claude Chat, without much additional prompting, other than I wanted it to look at my HRV data. It was processing for a bit, and came back and said it had identified 6 times throughout the last year with a clear outlier in my numbers - it suspected it was because I was sick, but a few of the dates looked familiar to me and it was from long haul flights.

I'm add basically every flight I take to Flighty - and it turns out you can export that data as well, yay! I went ahead and exported my flight data, and uploaded that to Claude as well - Claude came to the same conclusion as I (yay, me!) and saw a pattern that long haul flights tanked my data.

It ended up making a custom HTML dashboard showcasing some data.

It overlaid the flights on the graph (rust is long-haul flights, and sage is shorter flights)

Based on the data, it takes about 2 full days after my long distance flight for me to recover to anything close to my baseline before my flight.

I could of course have done all of this exploration on it's own - but that would definitely have taken a lot longer. Interesting times we're living in :) (I hope it's safe to share this data with Claude 😅)
