Description of the study :

Our goal is to investigate the genes that control the biological clock that is responsible of your body temperature, hormone levels, urine production, vigilance, performance, mood, time perception, and sleep organization. The results of this study will help us better understand the underlying mechanisms of the biological clock which may provide useful solutions to some of the problems caused by jet-lag and night-shift work.

They will also visit the lab at various times throughout the screening procedure (duration of these visits vary among participants).
