Drowsiness is a state of feeling sleepy or tired, typically as a result of not getting enough rest or sleep. It can also be caused by certain medications, medical conditions, or lifestyle factors such as excessive alcohol consumption or sleep deprivation. When someone is drowsy, they may struggle to stay awake, have difficulty concentrating, and may experience slower reaction times. Drowsiness can be dangerous, especially when it occurs while operating vehicles or machinery, as it increases the risk of accidents.
