Epworth Sleepiness Scale

A scale used to evaluate sleep debt. Sleep debt is the cumulative effect of not getting enough sleep. A simple method of measuring your ESS score is presented below:

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

  • Sitting and reading
  • Watching TV
  • Sitting inactive in a public place (e.g a theater or a meeting)
  • As a passenger in a car for an hour without a break
  • Lying down to rest in the afternoon when circumstances permit
  • Sitting and talking to someone
  • Sitting quietly after a lunch without alcohol
  • In a car, while stopped for a few minutes in traffic
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
