 Epworth Sleepiness Scale (ESS)

Daytime sleepiness can be more than just feeling tired—it might be a sign of an underlying sleep issue. The Epworth Sleepiness Scale (ESS) is a simple, validated self-assessment tool that helps measure your level of daytime sleepiness. It can guide you in determining whether you may need further evaluation for a sleep disorder, such as sleep apnea or narcolepsy.

​

The ESS asks you to rate your chances of dozing off in eight common situations, such as while watching TV, reading, or sitting in traffic. After answering, you'll receive a score between 0 and 24.

Interpreting Your ESS Score

  • 0-7: It is unlikely that you are abnormally sleepy.

  • 8-9: You have an average amount of daytime sleepiness.

  • 10-15: You may be experiencing excessive daytime sleepiness and should consider discussing your results with a healthcare provider.

  • 16-24: You are likely to be excessively sleepy and may need medical evaluation to determine the underlying cause.

​

Why Take the ESS?

Daytime sleepiness can negatively affect your productivity, mood, and overall well-being. It can also increase the risk of accidents, especially if you're drowsy while driving or operating heavy machinery. The ESS gives you an easy way to reflect on your sleep patterns and take the first step toward addressing potential sleep issues. By recognizing these symptoms early, you can prevent long-term health complications and improve your quality of life.
