The effects on cognition of sleeping 4 hours per night for 12-14 days

(guzey.com)

I slept 4 hours a night for 14 days and didn’t find any effects on cognition (assessed via Psychomotor Vigilance Task, a custom first-person shooter scenario, and SAT). I’m a 22-year-old male and normally I sleep 7-8 hours.

I was fully alert (very roughly) 85% of the time I was awake, moderately sleepy 10% of the time I was awake, and was outright falling asleep 5% of the time. I was able to go from “falling asleep” to “fully alert” at all times by playing video games for 15-20 minutes. I ended up playing video games for approximately 30-90 minutes a day and was able to be fully productive for more than 16 hours a day for the duration of the experiment.

This is quite a experiment…
