Epworth Sleepiness Scale (ESS)
Measures excessive daytime sleepiness
Do you find yourself dozing off during the day? The Epworth Sleepiness Scale measures your likelihood of falling asleep in 8 common daily situations. About 3 minutes.
How sleepy are you during the day?
Not all tiredness is the same. Some people are physically exhausted but can stay awake. Others — even after what seems like enough sleep — find themselves nodding off at meetings, in cars, or while watching TV.
The Epworth Sleepiness Scale (ESS), created by Dr. Murray Johns in 1991, measures your general level of daytime sleepiness. It asks a simple question: in eight different situations, how likely are you to doze off? Sitting and reading. Watching TV. Sitting in a meeting. In a car stopped for a few minutes in traffic.
Each situation is rated 0-3. The total score gives a straightforward picture: below 10 is normal, 10-12 is borderline, and above 12 suggests you might have a sleep disorder worth investigating. The ESS is widely used in sleep clinics and research because it's quick and correlates well with objective sleepiness measures.
Note: if you're scoring high, it could be anything from not getting enough sleep to sleep apnea — the ESS flags the symptom, not the cause.
