Pittsburgh, body needs adequate sleep to maintain fitness. Poor-quality sleep due to a variety of disorders ranging from snoring to sleep soundly is not associated with risk of metabolic syndrome that can trigger heart disease.

In addition to heart disease, metabolic syndrome is also associated with 2 other serious illnesses ie diabetes and stroke. The risk for experiencing all three diseases can be predicted from several risk factors such as belly fat, high cholesterol and high blood sugar.

Now experts from the University of Pittsburgh adds another risk factor that is not less important, namely sleep disorders. This factor was revealed in a study conducted for 3 years on 812 people with an age range between 45-74 years.

In the study, the risk of metabolic syndrome in general increased 2-fold in participants who always snoring during sleep. While the participants are difficult to sleep, the risk rose 80 percent and the participants who always woke up in a condition not fresh rose 70 percent.

When investigated further, the researchers concluded that snoring habits associated with other risk factors that increase blood pressure and cholesterol levels. While it was difficult to sleep and wake in fresh condition is a risk factor in itself, is not associated with other factors.

“This is the first study that reveals a closer relationship between sleep disorders with metabolic syndrome risk,” said Professor Wendy M Troxel, who led the study.

In addition to the risk factors of metabolic syndrome, always snoring during sleep also showed a problem with the respiratory tract. In some cases, this condition can cause respiratory system stops for a moment while sleeping (sleep apnea).

The results of this study published in the journal Sleep issue of December 1, 2010.
