Have found indeed an increased risk of developing diabetes in short sleepers so it brings me now to the impact of poor sleep quality.
都发现睡眠时间短的人患糖尿病的风险更大下面我想讲一讲睡眠质量低所带来的影响
Independent of sleep duration and gives me pleasure again to showcase the work of my collaborator Dr. Tiscali.
这没有考虑睡眠时间长短的因素我很荣幸给大家展示我的同事塔莎莉博士的研究
She had thought that poor sleep quality as typical of aging and the increase of diabetes risk is typical of aging.
她认为随着年龄的增长人的睡眠质量就会下降患糖尿病的风险也会增加
And could the two be related and so she had the idea of giving the poor sleep quality of 17-year-old.
那么两者之间是否存在风险呢她想到了一个办法也就是将17岁青少年的低质量睡眠
To young healthy people in their 20s and so she did that by installing on each side of the bed amplifiers.
加到20多岁的健康年轻人身上她在床的两边各安装了一个扩音器
And then she was in the control room and each time the volunteer would enter the deep sleep also called slow-wave sleep.
然后她呆在控制室里每当志愿者进入深度睡眠时也就是慢波睡眠阶段时
She would send a sound of pitch and intensity calibrator so that the volunteer would not wake up.
她会发出尖锐的强度较大的声音并对声音进行校正这样志愿者虽然没有醒来
But would immediately revert to shallow sleep and she did that for 3 nights in a row She's normally a very nice person.
但马上又回到了浅睡状态她这样连续干了三个夜晚她其实是个好人
And so...this is a very difficult experiment she was very successful in that she was able to reduce slow-wave sleep from 80 minutes.
这是一个难度很大的试验她成功了因为她把慢波睡眠的时间从80分钟
Which is the normal amount in young healthy subjects to less than 10 minutes 3 nights in a row.
健康年轻人的正常慢波睡眠时间就是80分钟降到了10分钟以下连续三个晚上
Without changing total sleep time so the subjects did not fully aroused and without changing REM sleep time.
但没有改变睡眠的整体时间因此试验参与者并没有完全醒来他们的快速眼动期睡眠时间并没有改变
And then what she observed is a decrease of insulin sensitivity you remember that already.
她观察到试验参与人的胰岛素敏感性降低了你们记得这个内容吧
No change in beta cell function no increased release of insulin no compensation.
而β细胞产生的胰岛素却没有变化也就是没有增加胰岛素的量没有对此进行补充
