Individuals with sleep apnea often report which of the following feelings upon waking?

Individuals with sleep apnea frequently experience disrupted breathing during sleep, which leads to insufficient oxygen levels and fragmented sleep. As a result, they often wake up feeling not well rested. This chronic sleep disruption can lead to excessive daytime sleepiness and fatigue, making it challenging to feel refreshed or energized upon awakening.

The other feelings listed—being well-rested and energetic, motivated and focused, or calm and relaxed—are typically associated with restorative sleep, which those with sleep apnea struggle to attain due to the condition's impact on sleep quality. Thus, the experience of waking up without a sense of restfulness is a key characteristic of individuals suffering from this sleep disorder.
