Epworth Sleepiness Scale

The Epworth Sleepiness Scale is a measurement of how likely you are to doze off or fall asleep in various situations, compared to feeling just tired. The Epworth Sleepiness Scale (below) was developed by researchers in Australia and is widely used by sleep professionals around the world to measure sleep deprivation (not getting enough sleep). Use the following number scale to choose the best match for each situation, and then add up your points.

  • 0 = no chance of dozing.

  • 1 = slight chance of dozing.
