Are You Sleepy?

To assist physicians in their recognition of daytime sleepiness, Dr. Murray Johns of Melbourne, Australia designed and validated the Epworth Sleepiness Scale (ESS)1. It asks a patient to rate the chance of dozing during various daytime activities. In contrast to just feeling tired, how likely are you to doze off or fall asleep in the following situations? 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 change of dozing


Total Score:

A score of less than 8 indicates normal sleep function;
If you score 8 or higher, schedule an appointment with your family physician to discuss the possibility of a sleep disorder.
8 – 10, mild sleepiness
11 – 15, moderate sleepiness
16 – 20, severe sleepiness
21 – 24, excessive sleepiness
