YSK playing Tetris for a while (20 minutes in the study I’m gonna link) immediately (<6h) after a traumatic incident can disrupt the formation of visual/spatial memories associated with the trauma and reduce post-traumatic symptoms. Probably any game that requires visual/spatial thinking and holds focus we’ll would work, but like, might as well just keep a copy of Tetris on your phone just in case you or someone else might need it. I recommend an emulator and a copy of a console ROM so you don’t have to deal with ads or whatever in the current official Tetris apps. Even if this is BS it’s not like it’ll be harmful either.
