It seems all I do nowadays is work, be grumpy or read. Usually if I'm too grumpy to do anything I just sleep early, but I can't physically sleep enough for my mood these days.
Your methods will probably not work for me, but I think this might get my head working on ideas.
Besides that, I bet others will find some use for your ideas too.
I step away from the internet for a bit. Most often cooking. I love to cook and it is very relaxing, but I don't really eat much. So I tend to foist everything off on my partner.
If my partner isn't around or I have already fed her, then I probably play some relaxed video game like Rimworld (I play very chill colonies) or Stardew.
That first sentence is the most important part though.
