16 Jun Driving home after a night shift? Be careful.
Mulhall et al. recently published an article in the journal of sleep that looked to characterise objective + subjective sleepiness and driving events after working a nightshift. They also considered circadian (body clock) and homeostatic (drive to sleep from being awake a long time) factors.
They concluded that subjective + objective sleepiness and driving events are increased following night shifts, even during short (~30 minutes) commutes. These were exacerbated by an interaction between circadian phase and the duration of wakefulness prior to driving.
