Tangentially, anyone tried dry sauna therapy sessions at night before bed? It's helped me tremendously with sleep and more. It's a bit considered a luxury, but maybe you can find a gym or spa membership that's low cost.
I installed an IR sauna a few months back. I use it almost daily. Sleep has been fantastic since then and I recover from workouts much more quickly. Stretching is also much easier in it and I've easily increased my bent-over stretch by 3 inches since I started focusing on it.
