Have you ever experienced that nauseated-stomach, foggy-head feeling that comes over you from lack of sleep? Is the refreshed, energized mood that only a good night's sleep can bring, a memory from the past?

Let me give you some inside scoop on how your internal clock "ticks" to keep you in balance, and why the delicate balance of your clock can work to your advantage.

Circadian rhythms
Our body has an internal clock, known as the "circadian." It comes from the Latin word "about 24 hours." Our internal circadian "clock" dictates emotions such as when we feel sleepy, hungry, happy or sad.

Delicate balance of cues
This clock of yours can be affected by almost any kind of external cue: an alarm clock ringing, the amount of exercise you take in, or even the time you eat your meals. Understanding that your body's clock works off these cues may motivate you to pay attention to your schedule and notice your rhythms.

Daily routine
Even though life can bring us unexpected disruptions to our daily routines⎯ people with sleep problems need to be especially diligent to keeping a daily schedule. It is essential to keep some of your daily habits regular. Dedicating your energy to routines such as, eating three meals a day (about the same time each day), getting daily exercise (morning is best for your circadian clock) and sticking to a regular bedtime, can add up to a smooth running internal clock. Keeping yourself in rhythm contributes to sleeping well and that refreshed, energized mood becomes a reality and a welcomed part of everyday.
