Lack of #sleep significantly slows #reaction time, with impairments increasing with sleep debt, becoming comparable to alcohol intoxication (e.g., 0.07%-0.1% Blood Alcohol Content) after about 24 hours awake, leading to delays of tens to hundreds of milliseconds, and chronic restriction to 5-6 hours can yield similar cognitive deficits as total deprivation, impacting attention and decision-making. All critical when it comes to learning to drive. #drivinginstructor #drivingschool #learnerdriver
