A medical study conducted by Dr. Oluwasen Akinseye found a link between increased stroke risk and the amount of hours we sleep each night.
The preliminary findings which have not been peer-reviewed will be presented at the American Society of Hypertension’s annual scientific meeting in New York City.
The study drew on data gathered by the U.S. National Health Interview Survey conducted on a pool of 203,794 people presenting hypertension. Among these, it was found that people who reported sleeping less than five hours per night, as well as those sleeping more than eight hours per night are exposed to higher risks of a stroke.
Compared to people who typically log an average of seven to nine hours of sleep per night, or “healthy sleepers”, those who log less than five hours of sleep present 83 percent increased chances of suffering a stroke. The second category presents 74 percent increase in chances.
Although the study did not establish a direct link between sleep duration and stroke risk in patients with hypertension, it is believed that short amounts of sleep lead to higher levels of cortisol in the body. Sleeping longer than eight hours per night leads to the body releasing inflammatory chemicals. Both cases are representative of increased risks to suffer a stroke.
Overall, long sleepers presented a stroke risk of approximately 13.6 percent. Insufficient sleepers presented a stroke risk of 11.2 percent. Short sleepers presented a risk of 5.7 percent, while healthy sleepers only 5.4 percent.
The findings of the study are only preliminary and in certain aspects quite elusive. One of the issues is that the data from the U.S. National Health Interview Survey is based on self-reported periods of sleep. That is insufficient for a study to weigh in factors as quality of sleep which may impact the final results.
Nonetheless, the study is welcomed and further analysis is expected under the circumstance in which an approximate one third of the adult population in the U.S. presents hypertension and 800,00 people suffer a stroke on a yearly basis according to the U.S. Centers for Disease Control and Prevention (CDC).
Advances in medical research connected to stroke risks and prevention are much needed.
Also in 2015 a study conducted at the University of Cambridge provided similar information that persons sleeping more than eight hours per day had an average 46 percent higher chance of suffering a stroke.
