I used to work with Autistic kids.
To calm them down, the classroom used the color blue for dividers. Royal blue.
They would dim the lights and play calming music.
At other times, if the classroom was noisy, some of the kids would wear headphone earmuffs to block out the noise.
Some of them would wear a weighted vest for 20 minute intervals.
These kids were hyper sensitive to outside stimuli.
Maybe we are all a little bit Autistic and all of the noise and excessive stimuli is making us all go kind of crazy.
