Your Regular Bedtime Influences Your Cardiovascular Disease Risk

Studies have shown that early to bed, early to rise may make a man healthy, wealthy and wise, as well as less likely to develop type 2 diabetes and cardiovascular disease. A study published in Experimental Physiology on Nov. 19, 2022, verified that people who prefer to go to bed late have a higher risk of developing type 2 diabetes, cardiovascular disease and obesity. The study included 51 early birds and night owls who were well matched in age. All were sedentary and had metabolic syndrome. Both groups drew on the same number of calories for activity, but early birds tended to be more physically active in the morning and mid-day and burned more fat. They were more physically fit and more sensitive to insulin than night owls. Those who went to bed later tended to eat a diet higher in carbohydrates and metabolized sugar less efficiently.
