“After three night of sleeplessness myself, I woke up tipped against the wall, writing notes on the wall itself.”
Under the supervision of US Navy physician Lieutenant Commander John J. Ross and Dr. Dement, the experiment started to take effect after the second day without any closed eye, according to the researchers.
When Gardner was asked to repeat tongue twisters to gauge his emotional state, he started to falter.
Things had drastically deteriorated for Gardner after going three days without sleep. He apparently suffered from health problems including moodiness,
Inability to focus, short-term memory loss, paranoia, and hallucinations. According to Dement, “he was physically very fit.”
Therefore, we could always get him moving by taking him bowling or playing basketball, or anything similar. He would fall asleep right away if he closed his eyes.
