Difference Between Insomnia and Hypersomnia

Key Difference

Insomnia and hypersomnia are both sleep disorders, but they are characterized by opposite symptoms. Insomnia involves difficulty falling asleep or staying asleep, leading to inadequate or non-restorative sleep. It is often associated with fatigue, mood disturbances, and impaired performance during the day. Hypersomnia, on the other hand, is characterized by excessive sleepiness, with individuals having prolonged sleep episodes at night or excessive daytime sleepiness, even after adequate or prolonged nighttime sleep.
