Sleep Deprivation Equals Intoxication

principle

Going without sleep can impair you enough to resemble intoxication. Treat severe sleep loss as a safety condition, not evidence of commitment.

You can be completely sober and still be too impaired to drive: simply staying awake without sleep may leave you functioning as though you were drunk.

E1

Awake is not the same as capable

Consciousness creates a dangerous illusion of competence. You may be standing, talking, and trying to work while sleep loss has degraded the abilities that safe driving depends on. The useful comparison is functional: intoxication and severe sleep deprivation can both make an apparently awake person unsafe behind the wheel.

E1

A safety analogy, not an equivalence

The supplied material supports the comparison specifically as a warning about driving after going without sleep. It does not establish that every tired person is impaired to the same degree as every drunk person, or that the two states are biologically identical.

E1

Take the keys out of the decision

If you have been awake without sleep, do not negotiate with yourself about whether you feel alert enough to drive. Arrange a cab, public transport, a rested driver, or sleep before travelling.
