Explanation:

Question 2 (Getting less than how many hours of sleep...):

Research in sleep science shows that getting less than 6 hours of sleep can lead to slower reaction times. 8 hours is a recommended healthy sleep duration, 4 and 2 hours are extreme sleep deprivations but the key threshold for noticeable reaction time slowdown related to common sleep deficit studies points to less than 6 hours.

REM (Rapid Eye Movement) sleep is crucial for memory consolidation, especially for remembering information learned during the day. Digestion is more related to non - REM sleep and bodily rest, and hormone development has other regulatory mechanisms not primarily tied to REM sleep.

Studies on sleep deprivation and cognitive impairment show that being awake for 24 consecutive hours has cognitive impacts similar to being intoxicated (impaired judgment, reaction time, etc.). Anesthesia is a controlled unconscious state, and low blood glucose is a metabolic issue with different cognitive impacts.

Answer:

6 hours
