No! Don't Stop! :-)
That's why the next section I wrote described how to get rid of the
excess heat in a controlled fashio. Of course, simply just insulating
the room without giving it a lot of thermal mass or any form of control
of the heat production/exchange will not stabilize the room.

the prosperity and technological sophistication in the world is of no
use without that foundation.
