Which of the following is a consequence of increased sleep debt in daily life?

Increased sleep debt results in an accumulation of lost sleep, leading to a variety of negative effects on cognitive and physical performance. One of the most common and noticeable consequences of sleep debt is daytime sleepiness. When the body does not receive adequate rest, it struggles to maintain alertness and focus during the day. This can manifest as a constant feeling of tiredness, difficulty in staying awake, and decreased overall energy levels. Individuals may find it challenging to perform daily tasks and maintain concentration, which can further exacerbate the effects of sleep deprivation.

In contrast, options like improved performance, heightened concentration, and increased energy typically arise from adequate rest and recovery. Thus, when sleep debt increases, those positive outcomes often diminish, making daytime sleepiness a direct consequence of insufficient sleep.
