Ah... a good nights sleep. We all want to get in the recommended 7-8 hours, yet according to the National Sleep Foundation, almost one-third of Americans sleep 6.5 hours or less each night. So, not only are we walking around in a bad mood, eyes half open, giant cup of Joe in hand, but now research shows that we are actually putting our heart at risk!

Research by Dr. Alexandros Vgontzas, professor of psychiatry at The Pennsylvania State University in Hershey reveals that even modest sleep deprivation may be associated with low-grade inflammation, which can lead to a number of cardiovascular problems.

Vgontzas and his team of researchers deprived 25 men and women just two hours of sleep per night over a six-week period. They measured blood levels for immune-system molecules called cytokines, which are normally secreted during inflammation and infection. Both men and women in the study had increased concentrations of cytokines, which confirms lack of sleep may stimulate an increase in chronic inflammation.

This is troublesome, particularly because continuous inflammation has been shown to lead to hardening of the arteries, high blood pressure, stroke, heart disease and even heart failure. Also, lack of quality sleep has a significant effect on your blood sugar levels. If you are sleep deprived, it requires more insulin to balance your blood sugar levels, which, in turn, can lead to heart disease and a host of other health related problems.
