About Daytime Sleepiness

Daytime sleepiness, or excessive daytime sleepiness, is a condition where it is difficult for a person to maintain attention and alertness, which disrupts daily life and increases the risk of accidents and errors. It occurs regularly, even after sufficient sleep, and can be a symptom of a more serious illness.

What causes this condition?

Excessive daytime sleepiness may be caused by a variety of factors, such as sleep-wake disorders (restless legs syndrome or obstructive sleep apnea) or other health conditions (ranging from depression, anxiety, schizophrenia and lupus, to cancer, Parkinson's disease or multiple sclerosis).

Recommendations

If excessive daytime sleepiness is manifesting regularly and affecting your day-to-day life, don't hesitate to see your doctor. Your health provider will be able to identify the cause of your condition and determine the necessary cure. If necessary, tests to rule out any underlying conditions may be recommended.
