[truth_]

I have many problems with my postures thoughout the whole day (bad habits and WFH), but I exercise semi-regularly.

I do stretching, running, or swimming- one or multiple of these all year.

I guess that is what saves me from back pains and other trouble despite bad postures.

Even when I didn't exercise (before age 14), I did not have any back pains despite sleeping on a very hard mattress.

Talk to your doctor and/or do a little exercise regularly. That should help. Don't start exercising with existing back pain without consulting an expert, though.

It's not much and mostly right after sleep.

So, yeah, I'll do more training.
