THE EPWORTH SLEEPINESS SCALE
The Epworth Sleepiness Scale was developed by researchers in Australia and is used by sleep professionals to measure sleep deprivation. How likely are you to doze off or fall asleep in the following situations, rather than feeling just tired? This refers to your usual or recent way of life. Even if you have not done some of these things recently try to recall how they would have affected you. Use the following scale, choose the most appropriate number for each situation:

0 = would never doze 1 = slight chance of dozing 2 = moderate chance of dozing 3 = high chance of dozing

Situation	Chance of Dozing (0-3)
Sitting and reading	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
Watching television	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
Sitting inactive in a public place, for example, a theater or meeting	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
As a passenger in a car for an hour without a break	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
Lying down to rest in the afternoon	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
Sitting and talking to someone	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
Sitting quietly after lunch (when you've had no alcohol)	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing
In a car, while stopped in traffic	0 - would never doze 1 - slight chance of dozing 2 - moderate chance of dozing 3 - high chance of dozing

Epworth Sleeiness Scores (ESS)
If your score is 10 or greater and Excessive Sleepiness persists,
download this page and consider discussing your results with your physician or a sleep medicine specialist for medical advice. Excessive Daytime Sleepiness is almost always caused by an underlying medical condition that can be easily diagnosed and effectively treated.

An Epworth score of greater than 16 was seen in patients with moderate to severe sleep apnea, a condition which is associated with cessation of breathing and recurrent arousals during sleep.Inadequete sleep or sleep which is fragmented by other medical disorders may also be associated with Excessive Daytime Sleepiness.
