I would assume the room is an average room, in contrast to a warm you could swim in, trampoline you could play on or similar physical outlets.

The key thing, I would claim, from a "whole person" perspective, is that the contrast is "sit quietly, forget your body entirely and think" and "get stressed by bodily tension and start an uncontrollable argument with yourself" where "bring your mind and body into harmony through movement" isn't an options.
