In the first study of its kind, researchers found that people who go to bed early are more likely to be in better health and more physically active compared to people who go to bed later. The study looked at bedtime preferences (also called “sleep chronotypes”) of people with type 2 diabetes. They found that people who went to bed late and woke up late (evening chronotypes) had low levels of physical activity. In fact, these “night owls” exercise 56% less than people who go to bed early. We know that exercise helps people with diabetes manage their weight, blood pressure, and other risk factors. Regular physical activity can also lower heart disease and risk of death. As a result, people who go to bed late at night may put their health at greater risk. Lead researcher, Dr. Henson, says that understanding how bedtime preferences impact physical activity could help people with type 2 diabetes better manage their health. Healthy sleep impacts long-term disease, so you may be able to improve your lifestyle and health simply by going to bed earlier.
