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.
