 And then E is alterations in arousal or reactivity. So that's that hyperactivity. Autistic and ADHD people already have more reactive nervous systems. So this is going to be even more exaggerated with PTSD. So like a bigger startle response, this ties back to the amygdala. The amygdala is just firing of like, you have to be on guard for signals of threat. And so the body is just like so much energy, so much cortisol, which is our stress hormone, just pulsing through our bodies. So that heightened reactivity, which also makes sleep hard. And then sleep is already like baseline hard for autistic people. So if you're throwing PTSD on top of it, like, it's very important for like breaking sleep cycles and stuff, isn't it? Yeah. Yeah. Massive. And being able to get out of our stress response is really important for sleep. Yeah.
