Tips for Coping with Work When You Have a Sleep Disorder

Get Familiar with Your Body's Internal Clock

"People have an internal clock that regulates when they sleep, when they are alert, when they best digest their food, even when they fight disease," says Mansbach, a physicist and software engineer. "For most people, this clock is synchronized with day and night: alert in the day, asleep at night. For some people, however, it is not synchronized with day and night."

I find the clock image useful.

Circadian Sleep Disorders Network’s website sheds additional light: "Circadian means 'roughly daily.' The word was coined some 50 years ago from the Latin terms circa, about, and diem, day. Circadian rhythms cycle daily according to the 24-hour rotation of the earth, and they are internally produced in all living things."

Based on the statistics on the site, half a million people in the United States -- as many women as men -- are affected by lifelong delayed sleep, and it is thought to be responsible for 7 to 10 percent of cases of chronic insomnia.
