Sleep quality changes during overwintering at the German antarctic stations neumayer II and III : the gender factor
Purpose Antarctic residence holds many challenges to human physiology, like increased psychosocial tension and altered circadian rhythm, known to influence sleep.We assessed changes in sleep patterns during 13 months of overwintering at the German Stations Neumayer II and III from 2008 to 2014, with...

The decline in local sunshine radiation led to a 48 minutes longer time in bed (p<0.001), 3.8% lower sleep efficiency (p<0.001), a delay of 32 minutes in sleep onset (p<0.001), a delay of 54 minutes in sleep offset (p<0.001), and 11% less daily energy expenditure (p<0.001), for all participants in reaction to the Antarctic winter's darknessphase.
