Epworth Sleepiness Scale

The Epworth Sleepiness Scale calculator computes the level of sleepiness based on a sample of assessments under different circumstances.  

INSTRUCTIONS: For each life event, choose how like it is that you'll doze off as follows:

• No chance
• Slight chance
• Moderate chance

The Math / Science

Interpret the Epworth Sleepiness Scale as follows:

• (0 to  7) - It is unlikely you are abnormally sleepy.
• (8 to 9) - You have an average amount of sleepiness.
• (10 to 15) - You possibly have excessive sleepiness. Consider medical attention.
• (16 to 24) - You have excessive sleepiness. Seek medical attention.
