Sleep apnea prevents you from getting restorative sleep because your body constantly wakes up to breathe. The result? Crushing daytime fatigue affects every aspect of your life. This isn’t just feeling a little sleepy after lunch. This is nodding off during conversations, struggling to stay awake while driving, or finding it impossible to get through the day without naps. “Daytime symptoms may include fatigue, sleepiness, or exhaustion,” notes Dr. Edward O. Bixler in his research on sleep disorders.
