Why Do You Feel Sleepy While Driving?

[VanIsaac]

Driving can easily make you feel sleepy because monotonous road environments, especially on highways, have a hypnotic effect. Here is some additional information: 1. Drowsiness while driving is more common in summer. High temperatures and poor air circulation inside the car, particularly in the afternoon, make people prone to sleepiness. 2. Many people have the habit of staying up late, and most do not take naps, leading to drowsiness while driving to work the next morning or during midday drives. This is caused by poor rest and low mental energy. 3. People accustomed to napping may feel sleepy at their usual nap time due to their biological clock. Additionally, after meals, the digestive system requires more blood, diverting it from other parts of the body, including the brain. This reduces blood and oxygen supply to the brain, resulting in drowsiness.
