A 90-minute nap followed by a 30-minute nap is more effective in putting off drowsiness and fatigue than a single 120-minute nap during the overnight duty, according to a new study.
The study, published in the journal Scientific Reports, analysed the data of pilot studies on night-shift naps conducted from 2012 to 2018.
