What is a common symptom of sleep apnea?

Excessive daytime sleepiness is a hallmark symptom of sleep apnea. This condition is characterized by intermittent pauses in breathing during sleep, which leads to disrupted sleep patterns and insufficient restorative sleep. As a result, individuals often experience significant fatigue and drowsiness during the day. This excessive daytime sleepiness can adversely affect a person's ability to function, impacting their concentration, productivity, and overall quality of life.

In contrast, improved cognitive function, increased energy levels, and consistent dream recall are not associated with sleep apnea. In fact, the fragmented sleep caused by the disorder typically leads to challenges in cognitive processing and memory, rather than enhancements.
