睡眠不足可能伤害心脏

Emily Price 2018年09月11日

相比睡眠充足的人,睡眠不足者罹患冠心病或者中风的风险更高。

晚上好好睡一觉对健康越发重要。三项新近研究发现,夜间睡六到八个小时对心脏健康有益,而且可以降低中风的风险。

据美国媒体《今日美国》报道,上周欧洲心脏病学会的一次会议期间发布了相关研究结果。

其中一项研究发现,相比睡眠充足的人,睡眠不足者罹患冠心病或者中风的风险更高,也更容易因此死亡。另两项研究发现,睡眠不足者罹患心血管病和动脉硬化风险也更高。研究人员认为,睡眠不足引发的心血管病风险与吸烟或晚年患糖尿病导致的差不多。

研究报告的执笔者伊巴密浓达·丰塔斯博士在希腊的奥纳西斯心脏外科中心工作。他在一份声明中称:“尚需更多研究方能解释清楚原因。但我们确信:睡眠会影响一些生理过程,如葡萄糖代谢、血压和炎症,这些都对心血管病有影响。”

去年公布的一项研究中,美国加州伯克利分校的研究人员发现,睡眠的时间和人的寿命关系非常大。实际上可以断定,睡眠不足会折寿。该研究还发现,45岁及以上年龄段的成年人,若每晚睡眠时间不足六小时,患心脏病或中风的几率比起睡七八个小时的同龄人高出一倍。

缺少睡眠也可能造成体重增加、上瘾复发,也更容易患上老年痴呆症。

Getting a good night’s sleep just became more important. Three new studies found that getting between six to eight hours of sleep nightly can do wonders for your heart’s health and can help lower the risk of a stroke.

The research was presented last week during a meeting of the European Society of Cardiology, USA Today reports.

One study found that people who didn’t sleep enough had a greater risk of developing or dying from coronary artery disease or stroke, while the other two found that people who don’t sleep enough face a higher risk of cardiovascular disease and hardened arteries. Researchers compared the cardiovascular risk of not getting enough sleep to the effects of smoking or having diabetes later in life.

“More research is needed to clarify exactly why, but we do know that sleep influences biological processes like glucose metabolism, blood pressure and inflammation – all of which have an impact on cardiovascular disease,” Dr. Epameinondas Fountas, the study’s author who works for the Onassis Cardiac Surgery Centre in Greece, said in a statement.

Last year, a study by researchers at the University of California at Berkeley found a strong correlation between the amount of sleep people get and how long they live, in essence determining that sleeping less leads to a shorter life expectancy. That study found that adults age 45 and older who slept less than six hours nightly were 200% more likely to have a heart attack or stroke during their lifetime than those who slept seven or eight hours.

A lack of sleep has also been associated with weight gain, relapses in addiction, and the development of Alzheimer’s.

The American Academy of Sleep Medicine and the Sleep Research Society suggests that people sleep at least seven hours each night.
