Feeling a tad drowsy and looking to put a number on it? Welcome to the world of the Epworth Sleepiness Scale (ESS)! You might be wondering, “How can a sleepiness scale be engaging?” Well, hold on to your nightcaps, because this is way more exciting than counting sheep!

Calculation Formula

The ESS calculation is a piece of cake. You simply rate eight common scenarios on a scale of 0 (wouldn’t doze if my life depended on it) to 3 (high chance of dozing). Add your ratings together and voila! You’ve got your total score.

ESS Score = Sum of all scenario scores

ESS Categories

ESS Score Sleepiness Level
0 – 5 Lower Normal Daytime Sleepiness
6 – 10 Higher Normal Daytime Sleepiness
11 – 12 Mild Excessive Daytime Sleepiness
13 – 15 Moderate Excessive Daytime Sleepiness
16 – 24 Severe Excessive Daytime Sleepiness
