Excessive Daytime Sleepiness
Excessive daytime sleepiness is a condition in which a person feels overwhelmingly drowsy or fatigued during the day, even after what appears to be adequate nighttime sleep. This sleepiness can interfere with concentration, work performance, driving, and overall quality of life. It is not a diagnosis on its own, but rather a symptom that may indicate an underlying medical or lifestyle issue.
People with this condition may unintentionally fall asleep during meetings, conversations, meals, or while watching TV. In more severe cases, they may doze off while driving or operating machinery, putting themselves and others at risk. The drowsiness may feel unrelenting, regardless of how much sleep the person gets at night.
It is important to distinguish excessive sleepiness from normal tiredness. True excessive sleepiness persists for weeks or months, does not improve with rest, and often comes with other symptoms such as memory issues, mood changes, or sleep disruptions.

In South Africa, this sleepiness is common but often overlooked. Many people blame stress, workload, or poor diet, without realising it could signal a sleep disorder or medical condition. With increased public awareness and access to sleep medicine specialists, more individuals can receive proper diagnosis and support.
Understanding this sleepiness is essential to addressing its root cause and improving both mental and physical wellbeing.
