Our results indicate that (1) chronic DLAN exposure
does not significantly influence sleep architecture or
homeostasis and (2) normally distributed body masses
show marked relationships to amount of time in wake
and SWS vigilance states, as well as to maximum time
spent in sustained wakefulness. These data lend support
to previous results suggesting a sleep-independent
mechanism of DLAN on metabolic, immune, and
affective phenotypes. Therefore, researchers interested
in the chronodisruptive effects of chronic light exposure
should consider using DLAN to control for sleep
disturbances in future research
