Scoring

0-5 points: For one reason or another, you seem to be getting too much sleep. You definitely lack energy. Try going to bed a little later, waking up a little earlier, and getting more exercise. If you still feel lethargic or obsessed with sleep, check in with your doctor. You may have an underlying condition that's causing you to feel sleepy all the time.

6-11 points: Although you have occasional symptoms of sleep loss, you tend to get the right amount of sleep for your needs. Congratulations . . . you're right in the middle of the PH Zone.

12-17 points: Your body and mind are feeling the wear and tear of sleep loss. Never mind what the studies say about sleep requirements-your body is telling you that you're not getting enough.

18-24 points: Your exhaustion affects you both physically and psychologically. You can't be healthy when you're this tired.
