The Epworth Sleepiness Scale


How likely are you to doze off or fall asleep in the situations described below under normal circumstances (i.e., excluding times of over-exertion and sleep deprivation)?

Use the following scale to choose the most appropriate number for each situation:

0 = Would never doze
1 = Slight chance of dozing
2 = Moderate chance of dozing
3 = High probability of dozing

Situation (rate each on a scale of 0-3)

  • sitting and reading
  • watching TV
  • sitting, inactive, in a public place (i.e., theatre or meeting)
  • as a car passenger without a break for an hour
  • lying down to rest in the afternoon as circumstances permit
  • sitting and talking to someone
  • sitting quietly after lunch (without alchohol)
  • in a car, driving, but while stopped for a few minutes in traffic

If your points total 10 or more, you are considered borderline sleep-deprived. If 12 or higher, you should seek medical attention immediately.

Alternate spelling: sleep apnoea | Common misspellings: sleep apnia, sleep apena, sleep apneia
