睡眠不足影响基因,你今天睡饱了吗?1

Getting too little sleep for several nights in a row disrupts hundreds of genes that are essential for good health, including those linked to stress and fighting disease.

连续几个晚上睡眠过少会扰乱数以百计对身体健康必不可少的基因，包括那些与压力有关以及对抗疾病的基因。

Tests on people who slept less than six hours a night for a week revealed substantial changes in the activity of genes that govern the immune system, metabolism, sleep and wake cycles, and the body's response to stress, suggesting that poor sleep could have a broad impact on long-term wellbeing.

对连续一周每晚睡不到六个小时的人的测试揭示了控制免疫系统、代谢、睡眠和清醒周期以及身体应激反应的那些基因活动的明显变化，这表明睡眠不好对长期健康有广泛影响。

The changes, which affected more than 700 genes, may shed light on the biological mechanisms that raise the risk of a host of ailments, including heart disease, diabetes, obesity, stress and depression, in people who get too little sleep.

这些变化，影响超过700个基因，可能阐明了那些睡眠过少的人会增加一系列包括心脏病、糖尿病、肥胖、压力和抑郁等疾病风险的生物机制。

Previous studies have suggested that people who sleep less than five hours a night have a 15% greater risk of death from all causes than people of the same age who get a good night's sleep. In one survey of workers in Britain more than 5% claimed to sleep no more than five hours a night. Another survey published in the US in 2010 found that nearly 30% of people claimed to sleep no more than six hours a night.
