Exporting ANS and sleep recovery from Polar Flow

Hi all,
I’m new here and delighted at what I’ve learned to do so far. This site has been an immense help. In a nutshell, I’m not an athlete, but just trying to use my Polar Loop to see how to track my wellness. I’m facing upcoming cancer treatments and thought it would be a fun and distracting to see how my body responds.I’m an imaging scientist during and do a lot of work with statistical analysis of data, so I want to pull as much as I can from Polar. Unfortunately, as I imagine many of you already know, this is easier said than done. The export as a zipped JSON file from account.polar.com works pretty well, but they don’t let you access it enough. At first I thought it was every two weeks they would let you download, but I’ve been locked out longer than that and I think I read it was now 30 days. Since I’m blogging this weekly as well, that is a little too infrequent. Anyway, apologies if I’m redundant (I did search for Polar but only came across user names) and have a wonderful day!

Connect your Polar account: under Settings → Connections → Polar

and make sure to tick “Download wellness data”.

Once you have data imported, add Custom Charts on the Fitness page. There are several pre-built shared charts for sleep, HRV, etc.
