Daytime sleepiness test

The following questionnaire will help you measure your general level of daytime sleepiness. Answers are rated using the Epworth Sleepiness Scale (ESS), the same tool used by sleep experts worldwide.

Each item describes a routine daytime situation. Use the scale below to rate the likelihood that you would doze off or fall asleep (in contrast to just feeling tired) during that activity. If you haven't done some of these things recently, consider how you think they would affect you.

Please note that this scale should not be used to make your own diagnosis. It is intended as a tool to help you identify your own level of daytime sleepiness, which can be a symptom of a sleep disorder.

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 chance of dozing


Chance of dozing (0-3)

Sitting and reading
Watching television
