How large is your sleep debt?

The bigger the difference between the amount of sleep you need and the amount of sleep you get, the greater your sleep debt. A large sleep debt makes you more susceptible to illness and can lead to serious accidents. Insomnia contributes to poor performance in school and on the job, increases the likelihood of falling asleep behind the wheel, and takes the pleasure out of leisure activities. Reducing your sleep debt may help you live longer and better.
