Epworth Sleepiness Scale (ESS)
What is the Epworth Sleepiness Scale?
The Epworth Sleepiness Scale (ESS) is a widely used questionnaire that measures your general level of daytime sleepiness. This simple tool asks you to rate your usual chances of dozing off or falling asleep in eight different common situations.
Important: The ESS is a screening tool, not a diagnostic one. A high score suggests excessive daytime sleepiness and indicates that you should consult a doctor for further evaluation.
ESS Score Interpretation
| Score Range | Level of Daytime Sleepiness |
|---|---|
| 0 - 10 | Normal |
| 11 - 12 | Mild |
| 13 - 15 | Moderate |
| 16 - 24 | Severe |
A score of 11 or higher is considered to indicate excessive daytime sleepiness and may warrant further investigation by a healthcare professional.
Understanding Your ESS Score
Your score can help you understand if your level of daytime sleepiness is within a normal range or if it may be a cause for concern.
0-10: Normal range
A score in this range suggests that your level of daytime sleepiness is likely healthy and normal.
11-15: Mild to Moderate sleepiness
Scores in this range indicate you may have mild to moderate daytime sleepiness. It would be wise to review your sleep habits and consult a healthcare provider.
16-24: Severe sleepiness
A score this high indicates a severe level of daytime sleepiness and a high likelihood of an underlying sleep disorder. It is strongly recommended that you seek medical advice.
Why Daytime Sleepiness Matters
Excessive daytime sleepiness is not just about feeling tired; it can be a sign of serious underlying medical conditions like Obstructive Sleep Apnea (OSA), narcolepsy, or other sleep disorders. It can significantly impact your quality of life, work performance, and safety, especially when driving or operating machinery.
