Adherence
Sleep deprivation impairs cognitive and motor performance to a degree comparable to alcohol intoxication at or above the legal limit, significantly increasing the risk of motor vehicle crashes and work-related injuries.
Driving or operating machinery while sleep-deprived is as dangerous as driving drunk. If you are tired, do not drive. The risk of a fatal accident increases significantly because your reaction time and judgment are impaired to the level of legal intoxication.
GoodSupportsHIGH confidence
Sleep deprivation results in impairments in cognitive and motor performance that are comparable to those induced by alcohol consumption at or above the legal limit.
Why this rating
Supported by multiple studies on neurobehavioral function and accident statistics.

More from this paper
- Chronic sleep deficiency (defined as inadequate or mistimed sleep) acts as an independent etiological factor for cardiovascular disease, metabolic disorders (obesity, type 2 diabetes), and increased mortality, distinct from primary sleep disorders.Good
- Short sleep duration (≤6 hours/night) is associated with increased odds of obesity (1.5x) and type 2 diabetes, mediated by hormonal changes including reduced leptin, increased ghrelin, and elevated evening cortisol.Good
