How to download all Apple Watch health data, including sleep patterns and heart rhythm, for a specific time period?

I need to get all my sleep data that my Apple Watch records to my phone and download it to show how many times a night I wake up. I clicked on my icon, selected "Export All Health Data", waited for it to create the file, then emailed it to myself. When I opened it up, it was only my ECG and workout routines.

How do I get all the data? I don't want a summary. I want the actual data that shows how many times and how long I wake up every night. How many times I am off balance, my heart rhythm, etc.

How far back can I get it?

I would like it for at least this year and all of 2025.

It is very important that I get this data.

Any help is very much appreciated.
