And those with normal sleep time in the lab had normal cortisol levels and I think this is really interesting.

而那些在实验室正常睡觉的人他们的皮质醇水平也正常我认为这个现象很有趣

Because sleep duration I think is more important for the corticotrophin access than sleep quality.

因为我认为睡眠时间长短比睡眠质量更能影响促肾上腺皮质的分泌

So when we restrict sleep during the hours that the subjects would normally be sleeping we dimmed the lights.

当我们在试验参与人正常睡眠的时间里对他们的睡眠进行限制时我们会把灯光调暗

But not to extremes because if we go to extremes it would be very hard for them to stay awake.

但不会全关因为如果把灯全部关掉试验参与人就很难保持苏醒状况了

But so there is a gradation in the light intensity in the room where during the normal nocturnal period we reduced light intensity.

所以房间的灯光强度是设定了级别的在正常的夜间时期我们会调低灯光的强度

But your question I think is an important one because there is new data that have emerged from GMY Association studies.

但我觉得你的问题非常重要因为GMY联系研究得出的数据显示

Indicating that the nocturnal elevation of melatonin could play a role in the risk of diabetes beta cell function particularly.

夜间褪黑素水平的升高会增加糖尿病的风险特别是改变β细胞的功能

And so if...even a small amount of light can inhibit melatonin release and could have contributed.

因此 哪怕是一点点灯光也能够抑制褪黑素的分泌从而影响到

To our observation of reduced glucose tolerance so it's a good question .

葡萄糖耐受力的降低所以这个问题提得很好

课程简介和演讲视频

课程简介
本套课程讲解了睡眠对健康的多重影响。睡眠不足会改变身体的内分泌系统，打破激素的平衡，扰乱大脑对食物的选择和摄取从而引发肥胖，严重影响胰岛素的平衡进而引发糖尿病。不同年龄段的人群有不同的睡眠需求，一般而言，年轻人的睡眠需求高于老年人，但所有成年人都应保证每天8小时的睡眠时间。

老年人的睡眠时间减少并不是生理变化的自然结果，而是其他疾病造成的影响，衰老本身并不会降低睡眠需求。常见的睡眠障碍包括失眠、睡眠呼吸障碍、四肢不宁综合症、快速眼动期行为失调，患者需要就具体的睡眠障碍咨询专业的睡眠医生，确诊后有针对性的改善睡眠，进而提高整体的健康状况。

不同的睡眠障碍有不同的治疗方式，但认知行为疗法是所有治疗方法的首选，其次是器械治疗、药物治疗以及外科手术治疗。患者应养成良好的睡眠习惯，培养“睡眠卫生习惯”，改善睡眠质量，尽量避免擅自用药和药物滥用。
