I’ve been using my tinnitus to evaluate whether I got enough sleep or when I’ve become tired for years, so it’s nice to randomly trip over validation here that the link is universal to and not just a hyperlocal mutation. Thanks for posting this.

I suppose I wouldn’t have noticed this if I was trying to tune out tinnitus, but I’m just used to it? Not like anything is every quiet (my hearing is hyperactive), but, like, the tone and volume of it right now is “insufficient sleep but circadian forced us awake” so I need to be particularly measured and chill if I drive while it’s this loud.
