To prevent **fatigue** while driving, it is essential to maintain an appropriate environment inside the vehicle. One of the most effective recommendations is to **ventilate the interior of the vehicle** and maintain a **temperature between 20 and 23 degrees**. This helps the driver feel more comfortable and alert, reducing the likelihood of experiencing fatigue symptoms such as difficulty concentrating, heaviness in the eyes, and feelings of nervousness or irritability.

Maintaining an adequate temperature and good ventilation helps to avoid drowsiness and improve concentration, which is crucial for safe driving. Additionally, a cool and well-ventilated environment can help prevent the sensation of pressure in the head and sluggishness in movements, which are signs of fatigue.

Therefore, it is important to pay attention to these conditions inside the vehicle to ensure a safer and more comfortable journey.
