晚上好好睡一覺對(duì)健康越發(fā)重要。三項(xiàng)新近研究發(fā)現(xiàn)，夜間睡六到八個(gè)小時(shí)對(duì)心臟健康有益，而且可以降低中風(fēng)的風(fēng)險(xiǎn)。

據(jù)美國媒體《今日美國》報(bào)道，上周歐洲心臟病學(xué)會(huì)的一次會(huì)議期間發(fā)布了相關(guān)研究結(jié)果。

其中一項(xiàng)研究發(fā)現(xiàn)，相比睡眠充足的人，睡眠不足者罹患冠心病或者中風(fēng)的風(fēng)險(xiǎn)更高，也更容易因此死亡。另兩項(xiàng)研究發(fā)現(xiàn)，睡眠不足者罹患心血管病和動(dòng)脈硬化風(fēng)險(xiǎn)也更高。研究人員認(rèn)為，睡眠不足引發(fā)的心血管病風(fēng)險(xiǎn)與吸煙或晚年患糖尿病導(dǎo)致的差不多。

研究報(bào)告的執(zhí)筆者伊巴密濃達(dá)·豐塔斯博士在希臘的奧納西斯心臟外科中心工作。他在一份聲明中稱：“尚需更多研究方能解釋清楚原因。但我們確信：睡眠會(huì)影響一些生理過程，如葡萄糖代謝、血壓和炎癥，這些都對(duì)心血管病有影響?！?

去年公布的一項(xiàng)研究中，美國加州伯克利分校的研究人員發(fā)現(xiàn)，睡眠的時(shí)間和人的壽命關(guān)系非常大。實(shí)際上可以斷定，睡眠不足會(huì)折壽。該研究還發(fā)現(xiàn)，45歲及以上年齡段的成年人，若每晚睡眠時(shí)間不足六小時(shí)，患心臟病或中風(fēng)的幾率比起睡七八個(gè)小時(shí)的同齡人高出一倍。

缺少睡眠也可能造成體重增加、上癮復(fù)發(fā)，也更容易患上老年癡呆癥。

美國睡眠醫(yī)學(xué)會(huì)和睡眠研究學(xué)會(huì)建議，每晚至少睡七個(gè)小時(shí)。（財(cái)富中文網(wǎng)）

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.
