Frequently asked questions
How does sleep affect productivity?+
Each hour below your sleep need cuts focused work output by 5–15%. After two nights of <6h, cognitive performance equals a 0.05% blood alcohol level.
Is the productivity hit recoverable?+
Mostly, with consistent recovery sleep. But chronic deficit causes lasting deficits in attention and decision quality.
How is productivity loss measured?+
Researchers combine reaction-time tests, error rates, and self-report Work Limitations Questionnaires. Even one hour of sleep loss measurably degrades all three.
Are night owls less productive at work?+
Only when forced onto a Lion schedule. Match the schedule to chronotype and Wolves match or beat Lions on creative and complex tasks.
Does coffee fully offset sleep loss?+
No — caffeine restores reaction time but not working memory, error rates, or decision quality. The 'wired but cognitively dim' state is real.
Is presenteeism worse than absenteeism?+
Yes — research consistently finds presenteeism (showing up tired and underperforming) costs employers 2–3x more than missed days.
Can short naps recover productivity?+
Yes — a 20-minute afternoon nap improves alertness for 2–3 hours and reduces error rates in cognitively demanding work.
