sleep deprivation facts:
After missing one night of sleep, expect fatigue, reduced attention span and problems with short-term memory.
After missing 2 to 3 nights, one will also suffer poor coordination, muscle twitches, marked loss of concentration, impaired judgment, blurred vision, nausea, and slurring of speech. Often one will experience episodes of microsleep (briefly sleeping for a few seconds at a time, without being aware of it).
At about 4 to 5 days without sleep, expect extreme irritability, hallucinations, and delusional episodes.
After about 6 to 8 missed nights, add slowed speech, tremors in limb extremities, memory lapse, confusion concerning one’s own identity, unusual behavior, and paranoia to the list.
After 9 to 11 nights without sleep, fragmented thinking occurs (beginning sentences without completing them), and prolonged episodes of unresponsive “conscious stupor.”
