Figure 5: Short term effect of a change in alarm time.

From: The effects of self-selected light-dark cycles and social constraints on human sleep and circadian timing: a modeling approach

Figure 5

(a) Sleep timing over a three-week period where the alarm is set to 7:00 h for the first week and is changed to 8:00 h at the beginning of the second week. (b,c,d and e) show homeostatic sleep pressure, sleep duration, the minimum of the circadian wake propensity rhythm, and the number of hours per day of wake effort, respectively, over the same three-week period. Parameters are the same as for Fig. 4 a and d.
