A study released in the Journal of Clinical Endocrinology and Metabolism indicates people who go to sleep after midnight are more likely to develop heart disease and diabetes than those who turn in earlier. Even when both groups got the same amount of sleep, night owls faced a higher risk of developing cardiovascular disease as well as other health issues such as a decrease in muscle mass.
While researchers could not prove a direct cause and effect link between staying up late and heart disease risk, the study suggests that disturbing the natural sleep rhythm of the body combined with late night indulgences in unhealthy behaviors such as smoking, over eating, and sedentary activities are to blame.
Night Owls Develop More Heart Disease And Diabetes
All night owls in the study had increased body fat and triglyceride levels. Male night owls were at particular risk of diabetes and loss of muscle mass. Female night owls had more belly fat and were had a higher risk of developing metabolic syndrome.
This study suggests turning in before midnight could be a heart healthy habit!
