For creative work, use high-ceiling rooms or outdoor spaces; for detailed analytic work, use low-ceiling environments.

“If that were the case, I recommend if you want to do creative work during phase 2, the 9 to 16 hours of uh your circadian cycle, 9 to 16 hours after waking that is that you do that in the high ceiling room or maybe even outdoors out on a deck or on a patio because the highest ceiling of course is is the sky.”
