From: Circadian misalignment affects sleep and medication use before and during spaceflight
Representative raster plots for three astronauts during spaceflight. Plots show sleep (black boxes) and circadian temperature minimum estimates (circles) derived from actigraphy over 100 days of data collection during spaceflight. Day 1 begins in the upper left corner. Data are plotted by clock time as indicated on the lower axis.
