Knead — Brain Cooler

Slow touch

Your skin has a dedicated channel for gentle contact: C-tactile afferents, nerve fibers tuned to slow, soft touch at a few centimeters per second, whose activation correlates with pleasantness and calming rather than with discrimination.¹ They are part of an affective touch system that regulates arousal, distinct from the one that reads texture and shape.²

The blob rewards exactly that register: press hard and fast and it just wobbles; work it slowly and it yields. Squeeze it, stretch it, let it quiver back. Your hands get the full conversation, at the pace the calming channel listens for.
