Human factor: Physical factors
Explanation
The consumption of **stimulant substances** such as coffee can be useful for combating sleepiness **in the short term**.

However, once their effects wear off, it is possible to experience a **rebound effect**, which means that sleepiness and tiredness may return with greater intensity.
It is important to note that **drowsiness** is a state in which one feels tired and heavy, and it is a significant risk factor for traffic accidents. Although coffee can offer temporary relief, it is not a long-term solution for combating sleepiness at the wheel.
