According to a recent study, completed by the scientists from the Duke University Medical Center in Durham, USA, regular bedtime is important for heart health and metabolism.
A team of scientists examined the sleeping patterns of approximately 2,000 adults aged between 54 and 93. None of them had a history of sleep disorders. Having analyzed the received data, the researchers found that volunteers with irregular bedtime had a higher body mass index, the higher level of blood sugar and blood pressure, as well as increased levels of hemoglobin A1C.
The lead researcher Jessica Lunsford-Avery, Ph. D., an assistant professor in psychiatry and behavioral sciences from the Duke University Medical Center, says: “Heart disease and diabetes are extremely common in the United States, are extremely costly and also are leading causes of death in this country. To the extent we can predict individuals at risk for these diseases, we may be able to prevent or delay their onset.”
