According to a study published in the Journal of Sleep Research, how much we sleep and how well we sleep are directly associated with cardiometabolic disease.
In a study of 138,201 adult participants (mean age, 48.8 years) conducted by the University of Pennsylvania, it was found that sleep duration correlated significantly with obesity, diabetes, myocardial infarction, stroke, and coronary artery disease.
The researchers also found a significant association remained for obesity, myocardial infarction, and coronary artery disease even AFTER fully adjusting for variables that included physical health.
Notably, 'sleep disturbance' was defined very broadly as difficulty falling asleep, staying asleep, and sleeping too much. Fortunately, following treatment, the effects for obesity, myocardial infarction, and coronary artery disease were the most positive.
According to the researchers: "These data suggest that sleep disturbance may be an important indicator of cardiometabolic disease risk."
