Is hypersomnia harmful?
Hypersomnia, or excessive sleepiness is always potentially harmful in that if one is excessively sleepy, there is a tendency to fall asleep doing complicated tasks such as driving, and meeting up in accidents because of falling asleep at the wheel, or if one is operating machinery. Or in a variety of areas where one’s wakefulness, alertness, and concentration is required. So therefore, hypersomnia is by definition potentially harmful. Not only to oneself, but to others.
