Five hours' sleep is tipping point for bad health 五小時(shí)睡眠是健康身體的最低要求
研究人員表示，每晚至少睡五小時(shí)可能會(huì)降低五十歲以上人群患多種慢性病的幾率。他們說，健康狀況不佳會(huì)影響睡眠，但睡眠不好本身也可能是疾病的預(yù)警或威脅健康的風(fēng)險(xiǎn)。
Experts generally recommend we all get around seven or eight hours' sleep per night for good health. Now new research, based on a study of UK civil servants, suggest five hours' might be the bare minimum you can get away with.
專家通常建議，為了身體健康，我們每晚都要睡七到八小時(shí)左右?，F(xiàn)在，一項(xiàng)以英國公務(wù)員為調(diào)查對(duì)象的研究表明，五小時(shí)可能是避免威脅健康的最低睡眠時(shí)間。
The investigators from University College London and Paris City University tracked the health of 8,000 participants through their 50s, 60s and 70s to see if sleep duration might be linked to their chance of developing multiple chronic conditions such as cancer, diabetes or heart disease.
倫敦大學(xué)學(xué)院和巴黎城市大學(xué)的調(diào)查人員跟蹤調(diào)查了8000名參與者50歲、60歲和70歲期間的健康狀況，以了解他們的睡眠時(shí)間是否與他們患多種慢性病的幾率有關(guān)，如癌癥、糖尿病或心臟病。
The results suggest short sleep may be a risk or a marker for disease, and five hours a night is the tipping point.
研究結(jié)果表明，睡眠時(shí)間短可能是導(dǎo)致患病的風(fēng)險(xiǎn)或標(biāo)志，而每晚睡五小時(shí)則是健康狀況是否受影響的臨界點(diǎn)。
