Andrew Huberman experienced a grunting tic as a child that provided relief and occasionally returns when he is fatigued.

“when I was a kid uh I had a little bit of a grunting tick I used to I had a this intense intense desire to clear my throat um to the point where my my dad said like you need to stop that he used to squeeze my hand every time I do it and I used to hide in the back seat of the car in the closet to do it because it provided so much relief and then it eventually passed yes I wasn't medicated they never did anything about it every once in a while now if I'm very fatigued if I've been working a lot I notice it starts to come back I'll do this like kind of grunting”
