Why Do I Always Feel Sleepy While Driving?
2 Answers
Here are the specific reasons for feeling sleepy while driving: 1. Poor air circulation in summer: Drowsiness while driving is more likely to occur in summer due to high temperatures and poor air circulation inside the car, especially in the afternoon when the human body is prone to drowsiness. Driving on monotonous highways can further enhance the hypnotic effect, increasing the driver's sleepiness. 2. Biological clock: Drivers who are accustomed to taking naps are more likely to feel sleepy at their usual nap time after lunch due to their biological clock. Additionally, after eating, the digestive system requires more blood, diverting it from other parts of the body, including the brain, leading to reduced blood flow and oxygen supply to the brain, which results in drowsiness.
I've also experienced drowsiness while driving, mostly due to extreme physical fatigue. Continuous driving for over two hours easily leads to a groggy state, especially during afternoon or early morning hours. Dehydration accelerates fatigue, so remember to keep a bottle of mineral water handy for hydration. Recently, I've found adjusting the seat angle quite effective—a slightly more upright posture can enhance alertness. Before long drives, a 20-minute nap is recommended as more effective than drinking coffee. Listening to upbeat music or podcasts also helps, but keep the volume moderate. Most importantly, don't push through—when eyelids feel heavy, it's time to pull into a service area. Safety comes first. The dangers of fatigued driving are no less than drunk driving, with too many accidents occurring annually due to this.
