First 8h from waking: best for focused analytical work.
Light: bright, overhead, blue
Look up - actually move eyes up, not head up. Set screen at eye level or higher.
Work standing up from time to time
Limit interruptions
Second 8h: best for creative and interpersonal work
Light: lower, yellow
Look at eye level or below
Last 8h: best for sleep!
Light: as little as possible, dim, yellow, positioned low
Legs above waist induce relaxation
To force alertness: bright light, stand up, fill the bladder
