Excessive sleepiness is a condition characterized by an overwhelming desire to sleep during the day, even after a full night’s rest. It can interfere with daily activities, work, and social interactions. Common causes include sleep disorders like sleep apnea, certain medications, and lifestyle factors such as poor sleep hygiene or irregular sleep schedules. This condition can lead to serious consequences, including impaired cognitive function and increased risk of accidents. Treatment options may involve lifestyle changes, addressing underlying medical issues, or using devices like CPAP machines for those with sleep apnea. Recognizing and managing excessive sleepiness is essential for overall health and well-being.
