Symptom 8: Frequent Yawning
Frequent yawning is another symptom associated with hypersomnolence. Although yawning is a natural response to fatigue, those with excessive daytime sleepiness may experience more frequent and persistent yawning throughout the day.
Yawning is often an attempt by the body to take in more oxygen, increase blood flow to the brain, and help combat feelings of drowsiness. However, in individuals with hypersomnolence, this reflex may not provide the desired relief from sleepiness, and they may continue to yawn frequently.
Recognizing excessive yawning as a potential symptom of hypersomnolence can help individuals seek professional assistance and work towards addressing the underlying causes of their sleep disorder. (7)
