To effectively fight fatigue while driving, which of the following actions should be avoided?

Avoiding sleep is crucial when considering actions to fight fatigue while driving. Sleep is the primary way for the body to recover and recharge. Lack of sleep not only leads to a higher likelihood of experiencing fatigue behind the wheel but can also impair judgment, reaction time, and overall driving performance. It's essential to have adequate rest before driving to ensure that you are alert and fully aware of your surroundings.

To enhance understanding, the other options focus on specific behaviors that can help manage fatigue but do not directly address the fundamental need for rest. For instance, avoiding an overly warm vehicle helps maintain alertness because high temperatures can induce drowsiness. Similarly, avoiding heavy foods can prevent the sluggish feeling often associated with a full stomach, and steering clear of alcoholic beverages is crucial since alcohol can severely impair the ability to drive safely. While these actions can contribute to combating fatigue, they cannot replace the essential need for proper sleep.
