研究发现 周末赖床将死于心脏病的风险提高11%
Can enjoying late nights and lazy lie-ins at the weekends really kill you? That was the alarming claim made recently by U.S. researchers, who say the habit can raise our risk of dying from heart disease by 11 per cent. The danger lies in what sleep scientists at the University of Arizona in Tucson, in the U.S., call 'social jet lag' — where changing our sleep patterns at the weekend knocks our bodies and brains out of kilter. Sierra Forbush, a research assistant at the university's Sleep and Health Research Program, says changing your sleeping habits at the weekend can wreak havoc on your biological clock. The survey of 984 adults, published in the journal Sleep, found a link between people who habitually went to bed and rose late on weekends and an increased rate of cardiovascular disease and fatigue. Other studies have found links between lie-ins and other physical and mental problems. In 2015, a study of 225 volunteers by health psychologist Dr Patricia at the University of Pittsburgh, in the U.S., warned that significant shifts in sleep routines between workdays and weekends are likely to raise the risk of diabetes. Lie-ins may also diminish your ability to think. A study in April by Dr Michael Scullin, director of the Sleep Neuroscience and Cognition Laboratory at Baylor University in Texas, in the U.S., tested 28 students and found that when they caught up on lost weekday sleep with long lie-ins, they performed significantly worse in tests of attention and creativity. |
