I've noticed the swelling thing (or lack of it) too, Words, only for me it's my fingers that used to swell. My whole life this used to happen when I was exercising and my heart rate was up, now it doesn't.
Speaking of exercise, I've got into a good routine over the past month or so, with a view to improving my strength in particular. I use the Down Dog app, which has a yoga and a HIIT version. I'm doing 25 minutes of HIIT, followed by 15 minutes of yoga, every other day. I was pushing it a bit too much to begin with and trying to do it every day, but I was damaging my muscles and absolutely knackered. A day off in between sessions gives everything time to recover. Maybe when I've built up my strength I'll be able to do more.
I'm fairly fit, I'm just a bit weak in key areas, because I have a large frame. Resistance stuff against my heavy body is quite tough - push ups, core-based exercises etc. I have thunder thighs so leg stuff is relatively okay.
Down Dog also has a meditation app now, so I'm incorporating some of that to try to reduce stress as well (I try to do some kind of meditation every day). I've also been taking melatonin and a GABA supplement for about a week now, and I think it is making a difference to my stress levels.
I had to attend a Zoom court hearing on Tuesday, and while it was for an entirely trivial and non-stressful matter, it was the kind of thing that I would normally have major pangs of anxiety about anyway. But I felt nothing, I was quite cheerful and able to not think about it.
I wonder if all of this is doing anything at all to my weight set point!
