The findings have also unveiled that sleeping before 10 pm substantially reduces the risk of cardiovascular diseases by 25%. The author of the study claimed that the elevated risk can be outlined to the neutering of the circadian rhythm of the body.
The study is especially "intriguing" when it comes to the findings about women, said Dr. Roxana Mehran, an interventional cardiologist. https://t.co/gcMM8sq8rs— Betty C. Jung (@bettycjung) November 9, 2021
“The circadian system controls daily behavioral and physiological rhythms. Disruption to the circadian rhythm has wide-ranging implications, resulting in poorer cognitive performance and increased risk for various physical and mental health conditions, including cardiovascular diseases” said the lead researcher David Plans.
The central clock regulates the circadian rhythm in the entire body. Morning light adjusts this central clock which gets perceived by eye receptors, said Plans. Re-adjustment of the clock occurs when the morning light hits. Sleeping late can make a person miss this significant period. “If this occurs for a longer period of time the circadian rhythm gets distorted” added Plans. This results in effects on the physiological and behavioral rhythms that are destructive to health.
Plans claimed, that there is no such confirmation about the time of sleep as such to call it a risk factor. Dr. Harly Greenberg, chief of the division of pulmonary, sleep medicine, and critical care at Northwell Health in New Hyde Park, N.Y. commented that “these results highlight the importance of the body’s circadian rhythm and add to the growing evidence showing increased health risks including obesity, diabetes, hypertension, cardiovascular diseases, and even cancer when our daily schedules are misaligned with our circadian rhythm.”
The actual study was conducted by Plans, in which the sleep timings of a group of men and women were tracked by accelerometers worn on the wrist. The results showed the people getting cardiovascular diseases slept after 11 pm and the ones who had lesser health issues slept before 10.
