Carcolepsy: Why Do We Get Sleepy in Cars?

The video discusses the issue of driver fatigue, which contributes to 20% of road accidents. It explores the potential causes of drowsiness while driving, including white noise and car vibrations. Studies suggest that vibrations may activate the parasympathetic nervous system, causing sleepiness, while the sympathetic system tries to compensate. Future car designs might include better shock absorption to reduce this effect.

How did the heart rate patterns of participants in the vibrating group differ from those in the smooth ride group?

What potential future solution is suggested to minimize driver sleepiness caused by vibration?
