Epworth Sleepiness Scale PDF Free Download


In today’s fast-paced world, getting a good night’s sleep can often feel like a luxury. Many of us struggle with sleep-related issues, and one common problem is excessive daytime sleepiness. The Epworth Sleepiness Scale is a valuable tool in assessing and addressing this concern. In this article, we’ll delve into the details of the Epworth Sleepiness Scale, its significance, and how it can help individuals improve their sleep quality and overall well-being.

What Is the Epworth Sleepiness Scale (ESS)?

The Epworth Sleepiness Scale, often abbreviated as ESS, is a self-assessment questionnaire designed to measure a person’s daytime sleepiness. It was developed by Dr. Murray Johns in 1991 and has since become a widely used tool in sleep medicine and research.

The Importance of Identifying Daytime Sleepiness

Understanding the Impact

Daytime sleepiness can have significant consequences on an individual’s life. It can affect cognitive functions, productivity, and even lead to accidents. Identifying and addressing excessive daytime sleepiness is crucial for one’s overall health and well-being.

How Does the ESS Work?

The ESS consists of eight scenarios or situations commonly encountered in daily life. Respondents are asked to rate their likelihood of falling asleep in each of these situations on a scale of 0 to 3, with 0 indicating no chance of dozing and 3 indicating a high chance of dozing. The scores from these scenarios are then summed up to determine the overall level of daytime sleepiness.

Taking the ESS Questionnaire

The Scenarios

  1. Sitting and reading
  2. Watching TV
  3. Sitting inactive in a public place (e.g., a theater or a meeting)
  4. Being a passenger in a car for an hour without a break
  5. Lying down to rest in the afternoon
  6. Sitting and talking to someone
  7. Sitting quietly after a lunch without alcohol
  8. In a car while stopped in traffic for a few minutes

Interpreting Your ESS Score

Once you’ve completed the ESS questionnaire, you’ll receive a total score. Understanding this score is essential in assessing your level of daytime sleepiness:

  • 0-5: Normal daytime sleepiness
  • 6-10: Mild daytime sleepiness
  • 11-12: Moderate daytime sleepiness
  • 13-24: Severe daytime sleepiness

Why Is the ESS Important?

Identifying Sleep Disorders

The ESS is often used as an initial screening tool for sleep disorders such as sleep apnea and narcolepsy. It helps healthcare professionals identify individuals who may require further evaluation and treatment.

Tracking Progress

For those already diagnosed with sleep disorders, the ESS can also be used to monitor the effectiveness of treatment interventions. Regularly retaking the questionnaire can help individuals and their healthcare providers assess progress.


In a world where sleep is often sacrificed for the demands of modern life, the Epworth Sleepiness Scale provides a valuable means of assessing and addressing daytime sleepiness. By understanding your own level of sleepiness, you can take steps to improve your sleep quality and overall health.
