Positive effects of Red Bull® Energy Drink on driving performance during prolonged driving.

Summary: Long highway drives often lead to "highway hypnosis" and fatigue, making it harder to keep the car steady within the lane. In a controlled study using a driving simulator, researchers tested whether Red Bull® could help drivers stay safer during a four-hour haul. After two hours of driving, participants took a short break to drink either Red Bull or a placebo (a drink tasting the same but without the caffeine and energy ingredients). Those who drank the Red Bull showed significantly better driving skills in the final two hours—specifically, they wove out of their lane less, maintained a steadier speed, and felt less sleepy compared to those who had the placebo or drove without a break.
