中新網(wǎng)12月25日電 據(jù)香港《文匯報(bào)》報(bào)道，美國(guó)一項(xiàng)研究結(jié)果顯示，每晚睡眠少于5小時(shí)，有近三分一的人出現(xiàn)血管硬化，嚴(yán)重可導(dǎo)致心臟病。


　　科學(xué)家對(duì)495名年齡介乎35至47歲的男女進(jìn)行磁力共振掃描，檢測(cè)血管硬化狀況。首次掃描中各人血管狀況良好，但5年后第2次掃描，卻顯示每晚睡眠少于5小時(shí)的人中有27%患有血管硬化。相反，只要每晚多睡1小時(shí)，機(jī)率就會(huì)降至11%，睡7小時(shí)以上患血管硬化的機(jī)率則最低。研究建議，每晚應(yīng)該保證有6小時(shí)睡眠，對(duì)健康有利。
