The Washington Post: "Scientists may have found the perfect bedtime to keep hearts healthy"

"Many of us feel we’re never getting enough sleep, blaming young children, snoring partners, the stresses of life or uncomfortable pillows. Scientists in Europe have said that research into the links between sleep and heart health often relies on foggy recollections or unreliable sleep diaries. Now, by attaching wrist-worn accelerometer devices to more than 88,000 people, they have been able more accurately to monitor sleep patterns and say they could have found an optimal bedtime to keep hearts healthy. Going to sleep between 10 p.m. and 11 p.m. is associated with a lower risk of developing heart disease in comparison with earlier or later bedtimes, according to a study published...in the European Heart Journal — Digital Health."
