Drinking caffeinated beverages is better driver fatigue-fighting measure than listening to music, reveals a new research.
The simulated driving study that measured driver fatigue levels against the use of caffeine, music, or no stimulant, showed that drivers who used either caffeine or music as a stimulant felt significantly less tired than those who did not.
However, those who drank a caffeinated beverage to stay awake performed their driving tasks much better than those who listened to music or those in the control group.
Researcher ShiXu Liu said that even though both caffeine and music keep drivers feeling more awake, caffeine also helps them maintain good driving performance.
Liu added that music, on the other hand, can distract drivers, which may explain why driving performance is not significantly improved when it is used as a fatigue countermeasure.
