The main reasons for always feeling drowsy while driving include lack of sleep, weather and driving environment issues, and having a heavy lunch. Lack of sleep: The primary reason for feeling drowsy while driving is insufficient rest and poor mental state. Many people have the habit of staying up late, and most do not get the recommended 7-8 hours of sleep. Inadequate sleep can lead to drowsiness when driving to work the next morning. Weather and driving environment issues: Drowsiness while driving is more common in summer due to high temperatures and poor air circulation inside the car, especially in the afternoon when the body is naturally prone to drowsiness. Driving on monotonous highways can have a hypnotic effect, further intensifying the driver's sleepiness. Heavy lunch: Generally, people who are used to taking naps after lunch tend to feel drowsy at their usual nap time 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. This reduces blood flow and oxygen supply to the brain, leading to drowsiness.
