A Good Night's Sleep Increases the Cardiovascular Benefits of a Healthy Lifestyle

A good night's sleep can increase the benefit of exercise, healthy diet, moderate alcohol consumption and non-smoking in their protection against cardiovascular disease (CVD), according to results of a large population follow-up study.(1) Results showed that the combination of the four traditional healthy lifestyle habits was associated with a 57% lower risk of cardiovascular disease (fatal and non-fatal) and a 67% lower risk of fatal events.(2) But, when "sufficient sleep" (defined as seven or more hours a night) was added to the other four lifestyle factors, the overall protective benefit was even further increased -- and resulted in a 65% lower risk of composite CVD and a 83% lower risk of fatal events.

As an explanation for the results, the investigators note that short sleep duration has been associated with a higher incidence of overweight, obesity and hypertension and with higher levels of blood pressure, total cholesterol, haemoglobin A, and triglycerides, effects which are "consistent with the hypothesis that short sleep duration is directly associated with CVD risk."
