The record for the longest period without sleep is 18 days, 21 hours, and 40 minutes, with symptoms like hallucinations reported by the record holder.
The record for the longest period without sleep at 18 days, 21 hours, and 40 minutes is supported by some sources, but there is conflicting information regarding the official longest recorded time. Randy Gardner is often credited with the longest scientifically observed record of 11 days. The Guinness World Records has ceased recognition of sleep deprivation records due to health concerns. Therefore, while the specific claim about Robert McDonald's record is mentioned in some web sources, it is not universally recognized or certified by authoritative records databases, leaving some uncertainty about its accuracy.
