Use this Tool to Measure Sleep Deprivation

The Epworth Sleepiness Scale was developed by researchers in Australia and is widely used by sleep professionals around the world to measure sleep deprivation.

How likely are you to doze off or fall asleep in the following situations, in contrast to just feeling tired? This refers to your usual way of life recently; however, if you haven't experienced the situations recently, think about how they've affected you in the past.

Use the following scale to choose the most appropriate number for each situation:


0 = no chance of dozing

1 = slight chance of dozing

2 = moderate chance of dozing

3 = high chance of dozing


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


  • If your score is < 8: You have a normal amount of sleepiness.
  • If your score is 9: You have a average amount of sleepiness.
  • If your score is > 10 and less than 15: You may be excessively sleepy and should talk to your health care provider.
  • If your score is > 16: You are excessively sleepy and should seek medical attention.
