Step-by-step explanation:
When you are struggling to stay awake while driving and realize that you may have "dozed off" for a few seconds, this shift in your brain activity is called a microsleep.
A microsleep is a brief episode of sleep that can last anywhere from a fraction of a second to a few seconds. During a microsleep, your brain briefly shuts down, which can be extremely dangerous if you are behind the wheel of a car.
To prevent microsleeps while driving, it's important to prioritize getting enough sleep at night, take regular breaks during long drives, and avoid driving when you are drowsy or fatigued.
