When preparing for summer driving, many people focus on their vehicle but forget that high temperatures can also affect the driver. Heat, dehydration and fatigue can reduce concentration, slow reaction times and make small driving errors more likely.
Driving requires constant attention, and as your body works harder to stay cool, mental performance can gradually decline without you noticing. Even mild dehydration can affect decision-making and increase irritability, especially on long journeys.
To reduce the impact of the heat, drink water regularly rather than waiting until you feel thirsty, and take planned breaks to rest and rehydrate. Before setting off, ventilate a hot vehicle and use the air conditioning to maintain a comfortable cabin temperature instead of making it excessively cold.
Fatigue can also develop gradually, particularly during long holiday journeys. While caffeine may provide a temporary boost, it is no substitute for proper rest. If you begin to feel tired, the safest option is to stop and take a break.
Remember that passengers, especially children and older adults, are also affected by the heat. Regular stops, plenty of water and a comfortable environment can make the journey safer and more enjoyable for everyone.
