How long do microsleeps typically last?

Microsleeps are brief episodes of sleep that typically occur when a person is awake but experiencing sleep deprivation or extreme fatigue. These episodes usually last around 4 to 5 seconds. During this time, a person may temporarily lose awareness of their surroundings, which can be particularly dangerous in situations requiring attention, such as driving. Understanding the duration of microsleeps is important as it highlights how quickly and unexpectedly they can occur, emphasizing the need for adequate rest to maintain safety and alertness while driving.
