I have the same problem. I also got some earbuds that do the ambient noise or noise cancelling and I can switch between modes easily. It does help some.
If I’m somewhere where I can’t get away from the chaos I’ll put on some lofi music with noise cancelling and that helps. If I need to pay attention (like if I’m grocery shopping with the kids) I will leave it on ambient mode. Some of the binaural beats playlists on spotify are really nice for calming my brain. I would definitely recommend checking those out.
If it is possible, getting outside and going for a walk, especially if you can get into grass or wooded environment is extremely helpful for me.
Something that may help (it helps me sometimes) is regularly doing some kind of heavy work, like lifting weights, pushups, etc. to really train the muscles. It helps calm my whole system down for hours. Working out regularly throughout the week has helped me a lot. I definitely notice when I miss some days.
I got rid of my alarm clock because the led screen was too bright. My phone charger has a bright blue light on it so I have to cover that up to sleep. I almost want to set up my bedroom with no electronics at all but I don’t think my wife would go for it
