Driving in **very hot** conditions can negatively affect driving. Excessive heat inside the vehicle can cause the driver to experience **drowsiness and fatigue** more quickly. This can lead to distractions and errors at the wheel, as the driver might need more time to react to unforeseen situations. Additionally, heat can increase **aggressiveness** towards other drivers.

To mitigate these effects, it is advisable to use **air conditioning** and keep the vehicle's temperature between **20 and 23 degrees**. It is also important to take more breaks during the trip, drink plenty of water or juices, and pay special attention after eating, as this is a time when drowsiness can increase. Wearing light, loose-fitting, and light-colored clothing can also help maintain an appropriate body temperature and reduce fatigue.

In summary, heat can increase fatigue while driving, making it crucial to take measures to maintain an appropriate temperature and stay well-hydrated and rested.
