How to manage driver fatigue?

Managing driving fatigue requires efforts in both prevention and emergency handling, with the key lying in maintaining physical condition and scientifically planning the journey. Before departure, ensure 7-8 hours of sufficient sleep and avoid staying up late or engaging in high-intensity activities. When driving, follow the "4-hour principle": do not drive continuously for more than 4 hours during the day or 2 hours at night, and stop at a service area for a rest of more than 20 minutes halfway. For long-distance trips, It is best to travel with a companion and take turns driving every 2-3 hours. The itinerary should avoid periods when the human body is prone to drowsiness, such as between 12:00 AM to 6:00 AM and 1:00 PM to 3:00 PM. If drowsiness occurs, immediately open the window for ventilation, lower the air conditioning temperature, or drink coffee to refresh oneself. The most effective way is to pull into a service area for a 15-20 minute nap. Some drivers rely on energy drinks, but excessive intake may cause subsequent fatigue to worsen. Therefore, moderate water intake and light exercise are more conducive to maintaining alertness.
