What is a consequence of staying up late, according to the text?

Feeling tired the next day is a direct consequence of staying up late, primarily due to the deprivation of necessary sleep that the body requires for rest and recovery. When individuals do not get enough sleep, it often results in fatigue, reduced alertness, and impaired cognitive function. This outcome highlights the importance of adequate rest in maintaining overall energy levels and mental sharpness. The other options suggest positive outcomes, which do not align with the typical repercussions of sleep deprivation, as staying up late generally leads to tiredness rather than increased energy or focus.
