Share

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.

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. If you have not done some of these things recently, think about how they have affected you in the past.

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