What it means
Excessive daytime sleepiness means feeling very drowsy during the day, beyond what is expected from a normal night's sleep. It can make it hard to stay awake while working, driving, or in social settings. Common causes include obstructive sleep apnea, narcolepsy, shift work, chronic insufficient sleep, sedating medications, depression, and underlying medical conditions. It increases the risk of accidents and impairs concentration and mood. A sleep study may be recommended to identify obstructive sleep apnea or other sleep disorders. Treatment depends on the cause and may include CPAP therapy, lifestyle changes, or medication.
