Heart Disease and sleep problems are often in bed together...

Researchers are beginning to reveal the two-way street between sleep and heart disease: Poor sleep can interfere with the heart, and heart disease can disturb sleep.

We have an internal clock that governs the body's systems. Sunlight helps set this clock. Not enough can throw off the clock and disturb the release of hormones and other chemical signals. This in turn causes fatigue and tiredness which can affect many other systems in the body. Researchers believe that it causes disruptions in underlying health conditions and biological processes like glucose metabolism, blood pressure, and inflammation.

The same may be true for oversleeping.  So it is said that an overall poor sleep pattern contributes to a higher risk for cardiovascular disease and coronary heart disease—regardless of age, weight, smoking and exercise habits.

If you aren't getting enough sleep, you may just need to "set your clock" by creating some healthy sleeping habits. If that doesn't work, or you are worried about your sleep or your partner's, see your doctor.
