What is the Epworth Sleepiness Scale?

The Epworth Sleepiness Scale (ESS) is a self-administered questionnaire used to measure daytime sleepiness. Developed by Dr. Murray Johns in 1991, it's widely used by healthcare professionals to assess sleep disorders and sleep quality. The scale helps identify conditions like sleep apnea, narcolepsy, and other sleep-related disorders.

How the Epworth Sleepiness Scale Works

The ESS consists of 8 situations where you rate your likelihood of falling asleep on a scale of 0-3. Your total score ranges from 0-24, with higher scores indicating greater daytime sleepiness.

0-10
Normal Sleepiness
11-15
Mild Sleepiness
16-20
Moderate Sleepiness
21-24
Severe Sleepiness
