Final answer:
Adequate sleep is crucial for reducing sleepiness and promoting optimal brain function.
Explanation:
The only way to reduce sleepiness is by sleeping. While drinking coffee or eating sugary foods may provide temporary alertness, these methods do not address the underlying need for restorative sleep.
Drinking caffeine may help you stay awake, but adequate sleep is essential for optimal brain function and performance. Avoiding caffeine and sugar close to bedtime, and finishing meals at least two hours before sleeping, can contribute to better sleep quality.
