Epworth Sleepiness Scale

The Epworth Sleepiness Scale (ESS) is an 8 item questionnaire that is used to determine the degree of daytime sleepiness in an individual. A score of 10 or more is considered mild sleepiness. If the score is 16 or more, then you are very sleepy and need to seek medical help. The questionnaire was developed by Dr Murray Johns in 1990 and still used widely to assess the level of someone’s sleepiness. It tests your chance of falling asleep in specific situations.
