Epworth Sleepiness Scale

The Epworth Sleepiness Scale is a questionnaire intended to measure daytime sleepiness. This can be helpful in diagnosing sleep disorders.

The instrument
How likely are you to doze off or fall asleep in the following situations, in contrast to feeling just tired? This refers to your usual way of life in recent times. Even if you have not done some of these things recently try to work out how they would have affected you.

Use the following scale to choose the most appropriate number for each situation:
 * 0 = no chance of dozing
 * 1 = slight chance of dozing
 * 2 = moderate chance of dozing
 * 3 = high chance of dozing

To check your sleepiness score, total the points:
 * 1 - 6: Congratulations, you are getting enough sleep!
 * 7 - 8: Your score is average
 * 9 and up: Seek the advice of a sleep specialist without delay
