What Is the Epworth Sleepiness Scale?
The Epworth Sleepiness Scale (ESS) is a simple questionnaire used to measure how likely someone is to fall asleep during everyday situations.
It is commonly used by healthcare providers and sleep specialists to evaluate excessive daytime sleepiness and screen for possible sleep disorders such as:
- Obstructive sleep apnea (OSA)
- Narcolepsy
- Chronic sleep deprivation
- Other causes of hypersomnia
The test is quick, easy, and widely used in sleep medicine.
