SAN FRANCISCO, NNC – A study revealed, people who often get woken up at night are more at risk of heart attack or stroke.
The disorder is atrial fibrillation, a state of an irregular heartbeat that affects one of 40 people.
US researchers have now found regular restless sleep can cause the condition by placing pressure on the body and causing electrical changes in the heart. The problem seems to come from sleep disorders.
Analysis of four studies involving more than 14 million patients showed people who did not sleep through the night are increasing their chances of having an irregular heartbeat by a third.
Atrial fibrillation (AF) has been linked to sleep apnea, where the throat closes and stops people breathing normally during sleep, this review, published in the journal Heart Rhythm, is the first to show regular restless night sleep can increase health risks.
"It's possible that improving regular sleep by exercising, sleeping at a reasonable hour regularly, and avoiding the use of the device before bed, as well as caffeine in the future, may help prevent AF," said lead researcher Dr. Gregory Marcus, of the University of California, San Francisco, quoted from Daily Mail, Wednesday (6/27/2018).
