Hypersomnia refers to medical conditions in which you repeatedly feel excessively tired during the day (called excessive daytime sleepiness) or sleep longer than usual at night. It is different from feeling tired due to lack of or interrupted sleep at night. ⁠ ⁠ If you have hypersomnia, you might fall asleep repeatedly during the day, often at inappropriate times, such as at work or during a meal. These daytime naps usually provide no relief from symptoms.⁠ ⁠ ⁠ ⁠ #hypersomnia #condition #sleepiness #sleep #sleeping #science #biology #medicine
